Indian Standard SPECIFICATION FOR

SULPHUR DUSTING POWDERS

( First Revision)

0. FOREWORD

0.1 This Indian Standard ( First Revision ) was adopted by the Indian Standards Institution on 29 May 1979, after the draft finalized by the Pest Control Sectional Committee had been approved by the Agricultural and Food Products Division Council and the Chemical Division Council.

0.2 Sulphur dusting powders are largely used. as fungicide and miticide.

0.3 This standard was first issued in 1972. With a view tn bringing this standard up-to-date, the Sectional Committee responsible for its for- mulation decided for its revision. Accordingly in this revision, require- ments for the various characteristics have been reviewed and verified in the light of experience gained in the country. Opportunity has been taken to incorporate modified method for estimating sulphur content and also various stipulations as laid by the Registration Committee of Central Insecticide Board as to the packing and tolerances of this product.

0.4 Sulphur dusting powder is generally manufactured to contain 85 percent ( m/m ) ,)f sulphur.

0.5 In the preparation of this standard due consideration has been given to the provisions of the Insecticides Act, 1968 and the Rules framed thereunder. However, this standard is subject to the restrictions imposed under these, wherever applicable.

0.6 For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accor- dance with IS : 2-1960’. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.

*Rules for rounding off numerical values ( revised).

IS : 6444 - 1979

1. SCOPE

1.1 This standard prescribes the requirements and the methods of samp$ng and test for sulphur dusting powders

2. REQUIREMENTS

2.1 Description - The material shall be in the form of a fine free flowing powder, yellow to brownish-yellow in colour, free from extraneous impurities and added modifying agents. It may contain fillers, such as, talc and pyrophyllite. The material, when dusted from, a hand rotary duster shall issue freely without clogging the nozzle or bridging.

2.2 The material shall also comply with the requirements specified in Table 1.

2.2.1.1 The actual value of sulphur content in the formulations shall be calculated to two decimal places and then rounded off to one decimal place before applying the tolerances stipulated in 2.2.1.

3. PACKING AND MARKING

3.1 The material shall be packed according to the requirements given in IS : 8190 ( Part I ) - 1976’.

3.2 Marking -The containers shall bear legibly and indelibly the following information, in addition to the information as is necessary under the Insecticides Act and Rules:

4 b) cl 4 e> f 1 la

Name of the material, Name of the manufacturer, Date of manufacture, Batch number, Net mass of the contents, Sulphur content ( m/m ), and The minimum cautionary notice worded as in the Insecticides Act and Rules.

3.2.1 When packed in bags ( see 3.1 ) the pictorial marking for ‘USE NO HOOKS. DO NOT PUNCTURE’, as specified in IS : 1260 ( Part II ) - 1973t shall be stencilled on the bags.

3.2.2 The containers may also be marked with the ISI Certification Mark.

Nom - The use of the IS1 Certiiication Mark is governed‘ by the provisions of the Indian Standards Institution ( Certification Marks ) Act and the Rules and Regu- lations made thereunder. The IS1 Mark on products covered by an Indian Standard conveys the assurance that they have been produced to comply with the requirements of that standard under a well-defined system of inspection, tenting and quahty control which is devised and supervised by ISI and operated by the producer. ISI marked products are also continuously checked by IS1 for conformity to that standard as a further safeguard. Details of conditions under which a licence for the use of the IS1 Certification Mark may be granted to manufacturers or processors, may be obtained from the Indian Standards Institution.

4. ‘SAMPLING

4.1 Representative samples of the material shall be drawn as prescribed in ‘Indian Standard methods for sampling of pesticides and their for- mulations’ ( under prepararion ).

NOTE -Till such time this standard is published, samples shall be drawn as agreed to between the parties concerned.

5. TESTS

5.1 Tests shall be carried out in accordance with the methods referred to in co1 4 and 5 of Table 1.

5.2 Quality of Reagents - Unless specified otherwise, pure chemicals and distilled water ( see IS : 1070 - 1977*) shall betemplnyed in tests.

NOTE - ‘Pure chemicals’ shall mean chemicals that do not contain impurities which affect the results of analysis.

APPENDIX A [ Table 1, Item ( i ) and clause 2.2.1 ]

DETERMINATION OF SULPHUR CONTENT

A-l. GENERAL

A-l.1 Two methods are prescribed, namely, Method 1 and Method II. For routine work, Method I is sufficiently accurate. For very accurate determination and in case of dispute, Method II shall be adopted.

A-2. METHOD I

A-2.1 Reagent

A-2.1.1 Carbon Disulphidc

A-2.2 Procedure - Weigh accurately about 1 g of the dry sample in the fritted glass extraction thimble and extract in the extraction apparatus for at least 15 minutes with carbon disutphide at the rate of one cycle per minute. Remove the container, dry and weigh. Report the per- centage insoluble r&due as foreign matter ( this includes ash ). Report

the percentage of sulphur as the difference between 100 and the percent- age of foreign matter.

Norm - Organic impurities may dissolve in carbon disulphide causing slight inaccuracy.

A-3. METHOD II

A-3.1 Principle - The sulphur present in the formulation is converted to thiosulphate using sodium sulphite and the thiosulphate content is determined iodimetrically. If thios’ulphate or other sulphur compounds are present a correction shall be made for them since both free and com- bined sulphur are determined.

A-3.2 Reagents

A-3.2.1 Sodium Sulphite - crystals ( Na803.7HzO ).

A-3.2.2 C@id Par&in

A-3.2.3 Dilute Formaldehyde - 40 percent ( v/v ).

A3.2.4 Acetic Acid - 20 percent aqueous solution.

A-3.2.5 Standard Iodine Solution - 0’1 N, freshly prepared.

A-3.2.6 Starch Indicator Solution - 0’5 percent, freshly prepared.

A-3.2.7 Carbon Tetrachloridc

A-3.3 Procedure

A-3.3.1 Weigh accurately sufficient quantity of the sample to contain 0 1 g of s&phur and transfer it to a conical flask, add 30 to 40 ml of water, 2 rf of sodium sulphite and liquid paraffin.

A-3.3.2 Attach the condenser, warm gently until the sulphur has disso- lved, then boil it for 40 minutes (see Note under A-3.4.1), cool and remove

the condenser. Add 10 ml of formaldehyde, 10 ml of acetic acid and 25 ml of carbon tetrachloride to the solution to, remove the paraffin. Titrate immediately with the standard iodine solution using freshly prepared starch indicator solution.

A-3.3.3 Carry out a blank determination of the reagents using the method given in A-3.3.1 and A-3.3.2.

A-3.4 Calculation

A-3.4.1 Sulphur content, percent by rnas = O’Oi2 06 (’ V-v ) N x 100
