A de f inite statement of pur -po se o r content sha l l be p la ced onthe beginning b f each chapter andprinc ipal subdivis ion.

3.3.1.5 The content of the technicalmanual shall be divided logically byvolume and part (if required because oflength or complexity), chapter, section,and as many additional levels of sub-ordinate headings (Prime, secondary,th i rd o rder , e t c . ) a s r equ i red . Break -down by section is not mandatory,section heads are used to divide a chap-ter into two or more clearly indepen-dent subchapters.

MIL-M-8l273A(WP)

presentation of material of a technicalmanual .

3 .1 .3 .1 N o m e n c l a t u r e . N om e n c l a -ture is divided into two categories,official and unofficial. The off ic ial

nomenclature (as indicated on assignedLD ’s , nomenc lature assignment sheets ,etc.) shall be used on first encounter.Unoff ic ial nomenc lature consists of ashortened or abbreviated term or thenomenclature usually associated with apiece of equipment. The princ ipal useof unofficial nomenclature in manualsis to conserve space or c lari fy con fus -ing des i gnat ions (see 3 .3 .3 .1 (e ) ) . Thefollowing rules shall govern the use ofnomenclature in a technical manual.

a . O f f ic ial nomenc lature, when used,shall be written as follows:

Torpedo Mk 37 Mod 1Sonar Computer-Indicator GroupAN/ BQA-3

Mine Mk 52 Mods O through 7Mine Mk 52 Mods 1 through 4 and 6Mine Mk 52, All Mods.

b. When re ferring off ic ial ly to two ormore similar items of equipment in thesentence, they shall be written asf o l lows :

Mine Mk 52 Mod 4 and MineMk55 Mod 0 are . . . . .

c . Unoff ic ial ly , the two mines in thepreceding example may be re ferred toco l lect ively as fo l lows :

Mines Mk 52 Mod 4 and 55Mod 0are . . . . .

d. Items not bearing a Mark and Moddesignation shall have, as their officialnomenc lature, the nomenc lature ap -pearing on the associated drawing and

L D . For purposes of further identi f i -cation, the official drawing number maybe used in conjunction with this identi-fication when required (as in assemblymanuals, etc).

e . When the nomenclature appearingon the drawing and LD is not sufficientlydes c r ip t ive , a modifier may be used indescriptive writing. For example, anitem designated officially as housingmay be described as the potentiometerhousing, thus differentiating it fromother housings described concurrently.

f . When unof f ic ia l nanenc lature isused to describe an item, the same

ature designation should benomen c luse consistently throughout the appli -cable portion of the manual.

g . Materiais such as hydraulic fluidsand lubricants shall be identified byname and part number or other Govern-ment Spec i f ication Number. I f anacceptable alternate material exists , i tshould be listed for emergency use.

h. Manu facturer ’s names and brandnames shall not be used (other than asspec i f ied for repair parts l ists ) unlessthey are required to differentiate be-tween two similarly identified itemswhich are not identical. Fo r e xample ,an equipment may accept either one oftwo power supplies. Both may haveidentical inputs and outputs and bemutual ly interchangeable . However, i fthey differ in internal construction,maintenance, calibration, etc . , i t maybe necessary to provide the brand ortrade name to distinguish between them.

i . In instances where material iscommer c i a l l y p rocured , a comple teidenti f ication by manu facturer ’s desig -nation catalog number, etc . , shall besupplied. When l ist ing commerc ial ly

procured material as a requirement forper forming a task, the words or equiv-alent shall be placed in parenthesesafter the name of the material.

3 . 3 .3 .2 A b b r e v i a t i o n s . A b b r e v i a -tions shall conform to the followingstandards :

a. All unusual and nonstandard ab-breviations shall be spelled out uponfirst encounter followed by the abbre-viation in parentheses. The sameabbreviation shall then be used through-out the manual.

b . Re ferences shal l be abbreviatedwhen in parentheses (Fig. ; Para. ; Vo l . ;etc.) and spelled out when not in paren-theses .

c . In tabular presentation, wherespace is at a premium, designations asin paragraph (b) may be abbreviated.

3.3.3 .3 Cap i ta l i za t ion and Pun c tua -t i on . The following standards shallgovern the use of capitals and punctua-t ion marks.

d. Quotat ion marks should be avo ided.items using alphabetical letters for de-scription shall not use quotation marksbut shall use the hyphen (e.g., O-ring;A - f rame ; I -beam ; C - c l amp ; e t c . ) .

e . The words Vo lume, Chapter ,Se c t ion , e t c . , shall appear in initialcapitals when used for reference in thetext.

f . Contro l des i gnat ions , when re f -erenced in procedural text , are nor -mally written in full capitals (see3.3.3.5(j)).

g . Commas should not be used be-tween hyphenated phrases (e.g . , 115 -vo l t 400 -cyc le three -phase power ) .

3 . 3 . 3 .4 U s e o f N u m e r a l s , S y m b o l s ,and Mathemat i ca l Express ions . Thefollowing standards shall be used in anynumerical or other mathematical ex -press ion :

a. Numbers less than 10 shall bewritten out. Numerals should be usedto express quantities of 10 or greater.

a. The first letter of each word of b. A sentence should not begin with aof f ic ia l nomenc lature shal l be capita - quantity expressed in Arabic numerals .l i z ed . Unoff ic ial nomenc lature, even I f necessary, the sentence should be re -though derived from off ic ial nomenc la - organized so as to place the numeralsture, need not be capitalized. (See elsewhere ; i f not possible , the numeri -3 . 3 . 3 . 1 ( a ) . ) cal quantity should be spelled out in words.

b. The fo l lowing terms shall be c . When used in frequently, Greekcapitalized; no period shall be required: letter . and other short symbo ls should

be spelled out. For example, in de -AC, DC, VAC, CF (constant scriptive text, the term delta tau isf requen cy } , CPS , VD C, R MS, R C. preferable to ; 22 kilohms is prefer-

able to 22 .c . Re ference designations shall be

capitalized; no hyphen or other punc- d. Symbols should be used where thetuation shall be required (e.g. C19; full name designation would prove bulkyR23; Q17; T1). or con fusing.

e. Complex equations and mathe -matical proofs should be avoided in allbut highly spec ial ized manuals . State -ments in English may be substitutedfor equations and proofs in cases wherethe explanation can be simplified by sodo ing.

f. In the presentation of a series off o rmulas , equat ions , e t c . , A rab i c nu -merals may be assigned sequential ly toeach expression to s impli fy re ferenc ingand proofs.

g . When possible , explanations in -vo lv ing mathematics more complexthan trigonometry should be avoided.In all cases, the level of mathematicsshall not exceed the level of trainingand experience of the user, as spec i f iedin the procurement document.

h. I l lustrations should be used tosupplement complex tr igonometricexplanations.

i . In descriptive text , the symbo ls+, - , ±, and • ( for degrees ) may beused. Percent and units of measure -ment (inches , feet , etc . ) shal l alwaysbe written out in text; however, thesymbols may be used in tabularpresentation.

j . Consistency in the use and mean-ing of symbols throughout the manualshall be maintained.

3 . 3 . 3 . 5 Conventions of FormatP r e f e r e n c e s ) . The conventions whichgovern the presentation of textualmaterial in the technical manual are asf o l lows :

a . Figure and table re ferences shouldbe adjacent to the appropriate figure ortab l e where v er pra c t i ca l . Ex cept ionsmay be made in the case of foldout

master schematics, funct ional blockd i a g r a m s , e t c.; these may be placed atthe end of a section or chapter so thatthey may be unfolded and utilized con-tinuously for reference throughout thepreceding material . Where the numberof illustration pages exceeds the num-ber of text pages, it may be desirableto place all illustrations together in aseparate sect ion, chapter, etc .

b . Figures and tables shall besequentially numbered with compoundnumbers within chapters. Fo r e xample ,Figure 5-17 connotes the seventeenthillustration in Chapter 5.

c . Pages within a chapter shall benumbered sequential ly from the f irstpage of a chapter, using compoundn u m b e r s .

d. Appendices shall begin with theletter A , and continue sequentiallythroughout the alphabet. Pages withinthe appendix shall be designated A-1,A -2 , B -1 , B -2 , e t c .

e . Text , tables , and i l lustrationsshall never be referenced by pagenumber except in the index and table ofcontents. Text shall be referenced bythe title of the chapter or heading asappropr ia te . Tables and i l lustrationsshall be referenced by table and figurenum b er .

f . Footnotes shal l be used sparingly.Footnotes for text shall be designatedby one or more asterisks at the appro-priate place in the text. The footnote isplaced at the bottom of that page, typedpage width and separated from the text bya broken line. Footnotes to tables shallbe designated by Arabic numerals begin-ning with 1 on each page. The footnote isplaced at the bottom of the table withinthe closing lines or border of the table.

g . When a small amount of materialis needed for re ference, either fromthe same or from another manual, thisport ion should be extracted, modi f iedin context, and reproduced as needed.Larger amounts of material should bere ferenced fully, inc luding manualdesignation, Vo lume, Part and Chapter .

h. Drawing numbers such asBUWEPS Dwg 1234567 shall bere ferenced without the word "number"and without the period after the ab-bre v ia t ion D w g . R e feren ce tocontractor-originated drawings shalluse the contractor 's name or identi f i -cat ion (e . g . , Cosmos Co rp . D w g1234567).

i . In order to incorporate additionalhardware changes with a minimum ofupgrading or change to the manual,unnecessary re ference to the Moddesignation or equipment should beavo i ded .

j . When controls, indicators,swi t ches , pane l s , e t c . , a re r e feren cedin procedural portions of the text, theexact , inscribed designation appearingon the equipment shall be used. If theinscribed nomenc lature or designationis not meaningful, an explanation shallappear upon first encounter. B e causemost control markings and paneldesignations are inscribed in capitalletters, capital letters shall be used inthe text. In those rare cases wherepanel markings are in lower casele t t e rs ( cer ta in commer c i a l l y procuredcomponents) the appropriate panelmarking shal l be either underscoredor set in italics as specified by theProcuring Act ivity.

k. Notes may be placed in the bodyof the text as indicated in 3.5. Notesare used to point out procedures or

ccndit ions which otherwise may be mis -interpreted or overlooked. They mayalso be used to clarify apparentlycontradictory or con fusing situations,or to re ference supplementary materialor information of interest to the reader.In the latter instance, a note in the textis preferable to a footnote if the supple-mentary material or re ference ialengthy.

3.3.3 .6 C on v e n t i on s o f F o r m a t(Sa fety ) . Cautions and warnings shouldbe used sparingly because of theirspecial importance to the user of themanual . The following guidelinesgoverning safety precautions shall beused :

a . Cautions shall be used to callattention to a procedure which, if notfo l lowed exact ly , can lead to damage ordestruct ion of equipment. They alwaysprecede the applicable portion of thetext. Format of the caution shall be asindicated in 3.5.

b. Warnings shall be used to callattention to dangerous or hazardouscondit ions inherent in procedural in for -mat ion . They always precede theapplicable portion of the text. F o r m a tshall bc as indicated in 3.5.

c . The criterion to be used in di f -ferentiating between a warning andcaution is one of physical injury to theperson per forming the procedures inthe text. If both damage to equipmentand personal in jury may occur, awarning shall be uoed.

d. Cautions and warnings do notusually appear in descriptive orgeneral ized text ; they are reservedfor procedural portions of the textin which the user wil l be per formingthe crit ical procedures.

8


e . G enera l i zed o r des c r ip t i v e po r -tions of a manual should be so writtenthat a user will not attempt to extractprocedural in formation which may havedangerous or hazardous implications.

f. When both a warning and a cautionprecede a step, the caution shallappear f irst .

g. Warnings shall be written in con-text so that they may be extractedverbatim for the sa fety summary (see3 .5 ) . Cautions shall also be written infull context.

3 .3 .4 Ap p l i ca b l e D o cu m e n t s . T herequirements stated in Section 3.3shall be supplemented by the followingdocuments .

3.3.4.1 GPO Style Manual. TheGPO Style Manual shall be usd as aguideline for all punctuation, abbrevi-ations, capital izations, and generaleditorial requirements where they donot conflict with the requirements inthis spec i f ication.

Minor solenoid: The solenoid associated with each magnetometer. Itsfunction is to produce a field whose polarity and strength balance the externalmagnetic field ar seen at the magnetometer. Magnetometer coils 1 and 2normally connect to the minor solenoid.

Gradient control circuit: A circuit which compensates, by means of avariable current fed to the minor solenoid, for the effects of localized mag-netic gradients present at each magnetometer coil.

For purposes of analysis, the magnetometer control system may be dividedinto five basic sections: the ambient field compensating circuit (the majorsolenoid); the excitation circuits; the measuring circuit; the gradient compen-sation circuit; and the deperm process monitoring circuits. Of these, themeasuring circuit. the major solenoid, and the deperm process monitoringcircuits are common to all magnetometers. The excitation circuits and thegradient compensation circuit are physically and functionary associated withindividual magnetometer coils. These basic circuit areas delineated inthe simplified schematic, Figure 3-4.

AMBIENT FIELD COMP ENSATING CIRCUIT. The ambient field compen-sating circuit consists of ALL (normally 96) major solenoid coils connected inseries and powered by the two regulated power supplies shown in Figure 3-4.The output current from the power supply is adjusted by means of the coarseand fine variable resisbro for all major solenoid coils. Gradient in theambient field as seen at individual magnetometer. are compensated by meansof the gradient compensation circuit described later.

Exaltation CIRCUIT. In Magnetometer Mk 6, the excitation circuit con-sicts of six coils and two non-linear thyrite resistive elements forming thebasic magnetometer circuit discussed in the previous sub-section. A total ofsix excitation coils are used in each magnetometer; these coils shown in Fig-ure 3-4 as LIA, B, and C, and LIA, B, and C, correspond functionally withthe two coils L1 and L2 of Figure 3-1. The coils designated B and C (Fig.3-4) serve to saturate their respective cores on each half-cycle. The coilsdesignated “A” provide the differential which drives one half of the circuitfurther tnto saturation tin the other.

To further this effect, the two non-linear thyrite elements, recistors whosevalue varies inversely with the current through them. are placed in serieswith LIA and L2A. These two elements, TH- 1 and TH-2, increase the dispar-ity of current flow through the two halve. of the circuit by presenting a de-creasing resistance to the coil, whose impedance is already decreased due tosaturation. The oppsite effect takes place in the other half of the circuit;the thyrite element in this case presente in increased resistance to the coilthrough which the lesser current flows. The two thyrite elements thus servetm “amplif y“ the current disparity by introducing an additional non-linearfunction in the circuit. The current flow over one complete cycle through oneexcitation coil will. therefore, resemble that down in Figure 3-5. As notedin the theoretical discussion in the previous sub-section, a high degree of

THEORY OF OPERATION. Fuzes inthe M900 series are initiated electricallyfrom either DC or DC/RF from the de-livery aircraft. Additional mechanicalsafety is provided in flight by an armingwire which io secured to the sleeve ofthe Mk 26 Safety Device.

Figures 2-3 and 2-4 are schematic-of fuzea M990C ad D, and Fuse M990E,respectively. Circuit differences in theC and D are indicated by the shadedareas on figure 2-3.

As noted above, -C, -D, and -E fusesare RF-initiated while the numberedmods (-D1, -D2, -E1, and 1E2) areDC-only initiated. (RF operation doesrequire a DC component however.) RFoperation allows pilot selection of arm-ing and functioning delay times as afunction of the RF frequencies fed to thefuze from the oscillators of the AWW-1Fuze Function Control Set.

RF OPERATION. Operation with RFis as follows:

1.

2 .

3.

DC and RF voltages are appliedsimultaneously at the input of thefuze (figure 2-3). The DC comp-nent immediately charges the ca-pacitor associated with squib S8.When charged, the capacitor actu-ates squib S8, thus isolating thefuze from further input. CapacitorsC1 and C3 are also charged.

One or more RF components arecoupled to the tuned LC circuitsacroe o the input transformer; thespecific tuned circuit which is ac-tivated is, a function of the fre-quency of the RF component.

AS shown in figure 2-3, each tunedcircuit is associated with one of thesquibs S1 through S6. When thecircuit is actuated, the associatedsquib is blown and its switch(shown by means of the brokenlines) is thereby operated.

4.

5.

6.

Resistors R1, 2, 3, and 4 controlthe time constant discharge rateof C1 and the associated chargingrate of C2. When C2 is ckrged tothe operating level of Thryraton

V1, the tube fires, causing thearming bellows to operate (figure2-5) (various combinatins of R1,2, 3, and 4 will provide the appro-priate arming delay time as indi -cated in table 2-3).

After the arming bellows have op- operated the rotor, the fuze is fullyarmed and all switches are in po-sition for detonation.

Upon impact, the trembler switchesare subjected to the required Gforces and close, thus completingthe firing circuit to the detonator.Depending on the functioning delayset into the fuze, the dischargetime of C3 is determined by re-sistors R5, 6, 7, 8, 9, and 10 asindicated in table 2-3. When C4has charged sufficiently, Thryra-ton V2 fires. With the firing ofV2, a live circuit to the detonatoris completed and the firing functionit initiated.

DC PRESELECTION. With DC-onlyoperation, the function of the fuse is.slightly less complex. As noted previ-ously, Fuzes D1, D2, E1, and E2 are“preselected. ” That is, the varioussquibs required to produce a succinctarming and functioning delay time arefired at the depot prior to issue. Thus,only the DC component is required toinitiate the fuze. Other than this pre -firing of squibs, operation is identicalto that described above.

Preslection of any fuze is accom-plished by pre-firing those squibs whichwill provide the aarming times shown intable 2-3. This is performed only at thedepot level and is not an authorized fieldmodification.

3. 6.4 Unc lassi f ied manuals requireno statement of such either on thecovers or the pages.

3.7 Interim Dra fts . As noted in 3.1,the specifications set forth in Chapter 3apply t o formal copy publications.Spec i f ications for al l dra ft copies issuedprior to the issuance of the formalcopy are usually specified in the Pro-curing Document. In general , produc-tion standards and art standards shallbe specified by the Procuring Activity.

3. 7 .1 Unless otherwise directed,the supplier shall provide the ProcuringActivity with the following drafts priorto the submission of the end product,e ither Prel iminary or Formal .

OutlineWr i t e r ’s Dra f tReview Dra ftPre l iminary Cop y

3. 7.2 The definitions of these draftsas given in Section 6 shall apply to therequirements of this spec i f ication.

3. 7 .3 Reduced -Coverage Dra ft

C o p i e s . When authorized by the Pro-curing Act ivity, r e d u c e d - c o v e r a g ewriter ’s dra fts and review manuals maybe submitted. This option is generallyinvoked for equipment and systemmanuals for which the hardware is in adevelopmental stage or when unexploredareas of knowledge or applications arebeing investigated. In pro jects of thisnature, there is a wide -spread timescale involved in the phases of develop-ment such as to render obsolete much ofthe material general generated in theearl ier phases of the program.

3. 7.3.1 Depth of Coverage. Thereduced -coverage option al lows less thancomplete technical description in all

areas of the manual. Organization,how e v er , should parallel the final prod-uct insofar as this is possible at thetime the dra ft copies are prepared. Ina redu ced - c ov erag e manua l , p rocedura linformation is presented in skeletalf o r m . The intent of the procedure isgiven in sufficient detail to allow cogni-zant engineering and technical personnelto evaluate the l ccuracy and adequacy ofthe procedure. Funct ional descriptionsare l imited to “black -box” coveragewith no requirement to present specificvalues of components, to lerances,w a v e f o r m s , e t c . In all areas wherespec i f ic in formation is unavailable, acomplete statement of proposed coverageshall be made.

3 . 7 . 3 . 3 R edu ced -Cov erag e ;Di f fe rence between Writer ’s and Review

D r a f t s . When separate writer ’s dra ftand review draft copies are requiredfor equipment and maintenance manuals(or in any other publication where ex-tensive procedural in formation isrequired ) , two levels of reduced -coverage are authorized. Fo r wr i t e r ’sdraft, the procedural steps only need tobe summarized ; no information on howto perform the steps is required and noexplanatory or transitional material isprov ided . In the writer ’s draft, theprocedures gene rally are written in amore passive -vo ice style . In the reviewdra ft , procedural in formation may alsoinclude transitional material which isexplanatory and tends to break up theprocedural in formation into b locks orspec i f ic tasks. This contrasts to sub -sequent drafts which contain not onlythe l teps involved, and the specifictransitional and explanatory data, but

51


MIL-M-81273A(WP)

also details the manner and techniquesinvolved in performing the steps.

3 .7 .3 .4 As mo re spe c i f i c da tabecomes avai lable , i t shal l be incor -porated into the review manual . Thisapplies not only to procedural informa-tion as detailed in 3. 7.3.3 above, butto funct ional descriptions, theory ofopera t ion , e t c .

4 . QUALITY ASSURANCEPROVISIONS

4 . 1 R espons ib i l i t y o f Supp l i e r .

4 .2 .2 W r i t e r ’s Dra f t and Rev iewDraft. Writer’s draft and review draftsshall be checked for conformity withthe outl ine, general editorial style ,content of illustrations and technicalaccuracy with respect to the subjectmatte r. The draft shall be clearlymarked to indicate its status as reviewmaterial only, thus restrict ing itspossible use by the Fleet as an opera-tional document.

4 . 2 . 3 P r e l i m i n a r y C op y . D e p e n d i n gupon the specific requirements of theProcuring Document, the Prel iminaryCopy may be (1) of a standard equal tothat of the formal manual, or (2) lessthan complete with respect to format,layout, quality of l rt, etc. It may alsobe less than complete technically if allhardware is not available. Thetechnical cove rage of the manual shallre f lect the design characteristic of al lavailable hardware at the specifiedengineering cut -of f date for Prel iminaryD ra f t s . If the standard is that of theformal manual , the requirements inparagraph 4.2.4 shall apply. I f lessstringent standards are spec i f ied, i tshall be checked editorially and typo-graphically l s described in paragraphs4.3.la, b, d, and e. An on-site review,according to 4 .3 .2 , shal l be conductedi f required.

4 . 2 . 4 F o r m a l M a n u a l . T h e f o r m a lmanual shal l con form to a l l spec i f ica -tions set forth in Section 3. Deskreviews (4.3.1 ) and on -site reviews( i f required by sub ject matter ) (4.3.2 )shal l be employed to ensure compliance.
