NATIONAL FOREWORD

This Indian Standard ( Third Revision ) which is identical with ISO 6506-1 : 1999 ‘Metallicmaterials — Brinell hardness test — Part 1 : Test method’ issued by the International Organizationfor Standardization ( ISO ) was adopted by the Bureau of Indian Standards on the recommendations ofthe Mechanical Testing of Metals Sectional Committee and approval o-f the Metallurgical EngineeringDivision Council.

This standard was originally published in 1959 and subsequently revised in 1968 and 1983. This revisionof the standard has been taken up to align it with ISO 6506-1 :1999 by adoption under dual numberingsystem.

In this revision, the use of steel balls have been discontinued in favour of carbide balls, to bring it in linewith the International practice.

In the adopted standard, some terminology and conventions are, however, not identical to those used inIndian Standards. Attention is especially drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be asread as ‘Indian Standard’.

b) Comma ( , ) has been used as a decimal marker while in Indian Standards, the current practiceis to use a point ( . ) as the decimal marker.

In this adopted standard, reference appears to the following International Standard for which IndianStandard also exists. The corresponding Indian Standard which is to be substituted in its place is listedbelow along with its degree of equivalence for the edition indicated:

METHOD FOR BRINELL HARDNESS TEST FORMETALLIC MATERIALS

( Third Revision)

1 Scope

This part of ISO 6506 specifies the method for the Brinell hardness test for metallic materials and is applicable upto the limit of 650 HBW.

For specific materials and/or products, particular International Standards exist (i.e. ISO 4498-l).

2 Normative references

The following normative documents contain provisions which, through reference in this text, constitute provisions of thispart of ISO 6506. For dated references, subsequent amendments to, or revisions of, any of these publications do notapply. However, parties to agreements based on this part of ISO 6506 are encouraged to investigate the possibility ofapplying the most recent editions of the normative documents indicated below. For undated references, the latestedition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently validInternational .Standards.

3 Principles

An indenter (hardmetal ball with diameter D) is forced into the surface of a test piece and the diameter of theindentation d left in the surface after removal of the force F is measured.

The Brinell hardness is proportional to the quotient obtained by dividing the test force by the curved surface area ofthe indentation. The indentation is assumed to be spherical with a radius corresponding to half of the diameter ofthe ball.

4.1 The Brinell hardness is denotedby HBW.

NOTE In former standards, in cases when a steel ball had been used, the Brinellhardnesswas denoted by HB or HBS.

4.2 The letters HBW are preceded by the hardness value and supplemented by an index indicating the testconditions in the order:

a) the diameter of the ball, in millimetres;

b) a figure representing the test-force (see Table 2);

c) the duration of application of test force, in seconds, if different from the specified time (see 7.5).

EXAMPLE 1 350 HBW 5/750 = Brinell hardness of 350 determined with a ball of 5 mm diameter and with a test force of7,355 kN applied for 10s to 15 s.

EXAMPLE 2 600 HBW 1/30/20 = Brinell hardness of 600 determined with a ball of 1 mm diameter and with a test force of294,2 N applied for 20s.

5 Testing machine

5.1 Testing machine, capable of applying a predetermined test force or forces within the range of 9,807 N to29,42 kN in accordance with ISO 6506-2.

5.2 Indenter, a polished hardmetal ball, as specified in tSO 6506-2.

5.3 Measuring device, as specified in ISO 6506-2.

NOTE A suggested procedure for periodic checks by the user is given in annex A.

6 Tes-t piece

6.1 The test shall be carried out on a surface which is smooth and even, free from oxide scale, foreignmatter and,in particular, free from lubricants. The test piece shall have a surface finish that will allow an accurate measurementof the diameter of the indentation.

6.2 Preparation shall be carried out in such a way that any alteration of the surface, for example due to heat- orcold-working, is minimized.

6.3 The “thickness of the test piece shall be at least eight times the depth of indentation. Values for the minimumthickness of thetest piece in relation to the mean diameter of indentation are given in annex B.

Visible deformation at the back of the test piece can indicate that the test piece is too thin.

7 Procedure

7.1 In general, the test is to be cawiid out at ambient temperature within the limits of 10 “C to 35 “C. Tests carriedout under controlled conditions shall be made at a temperature of (23 * 5) ‘C.

7.2 The test forces given in Table 2 shall be used.

7.3 The test force shall be chosen so that the diameter of the indentation d lies between the values 0,24 D and0,6 D.

The force-diameter ratio (0,1 02x F/D2) shall be chosen according to the material and the hardness test as indicatedin Table 3.

IS 1500:2005Is-() 6506-1 :1999

,.,.,

In order to test the largest representative area of the test piece, the diameter of the testing ball shall be chosen to beas large-as possible.

When the thickness of the test piece permits, a 10 mm diameter ball is preferred.

7.4 The test piece shall be placed on a rigid support. The contact surfaces shall be clean and free from foreignmatter (scale, oil, dift, etc). It is impodant that the test piece lie firmly on the support so that displacement cannotoccur during the test.

7.5 Bring the indenter into contact with the test surface and apply the test force in a direction perpendicular to thesurface, without shock, vibration or overrun, until the applied force attains the specified value. The time from theinitial application of force to the time the full test force is reached shall not be less than 2s nor greater than.8s.Maintain the test force for 10s to 15s. For certain materials, where a longer dwell time is required; this time shall beapplied with a tolerance of ~ 2s.

7.6 Throughout the test, the testing machine shall be protected from significant shock or vibration which caninfluence the test result.

7.7 The distance from the edge of the test piece to the centre of each indentation shall be a minimum of two and ahalf times the mean indentation diameter.

The distance between the centres of two adjacent indentations shall be at least three times the mean indentationdiameter.

a For the testing of cast iron the nominal diameter of the ball shall be 2,5 mm,5 mm or 10mm.

7.8 Measure the diameter of each indentation in two directions perpendicular to each other. The arithmetic meanof the two readings shall be taken for the calculation of the Brinell hardness.

NOTE For some testingmachines, the followingshouldbe used:

— the average of a greater number of symmetricallyplaced measurements;

— an assessment of the projectedindentationarea intothe materialsurface.

7.9 Table C.1 (see annex C) contains calculation tables which shall be used to determine the Brineil hardness fortests on flat surfaces.

8 Uncertainty of the results

The uncertainty of results is dependent on various parameters which maybe separated into two categories:

a) parameters dependent on the Brinell hardness testing machine (including the uncertainty of-the verification ofthe testing machine and on the calibration of the reference blocks);

b) parameters dependent on the application of the test method (variation of the operating conditions).

NOTE A comptete evaluation of the uncertainty should be carried out according to the Guide to the Expression of

Uncertainty in A4easurernent[11.Indicative values of the extended uncertainty at a confidence level of 95 ‘X. can be taken to beequal to the maximumpermissibleerror given inTablr+ 2 of ISO 6506-2:1999.

9 Test report

The test report shall include the following information:

a) a refewnce to this International Standard, i.e. ISO 6506-1;

b) all details necessaryfor the complete identification of the test pi&ce;

c) the test temperature if it is not within the limits (23*5) “C;

d) the result obtained;

e) additional requirements outside the scope of this part of ISO 6506;

f) details of any occurrence which may have affected the result.

NOTE 1 There is no general process of accurately converting BrineH hardness into other scales of hardness or into tensilestrength. These conversions should therefore be avoided, unless a reliable basis for the conversion can be obtained bycomparative tests.

NOTE 2 It should be noted that for anisotropic materials, for example those which have been heavily cold-worked, there maybe a difference between the lengths of the two diameters of the indentation. The specification for the product may indicatelimits for such differences.

Annex A(informative)

Procedure for periodic checks of the testing machines by the user

The indirect verification procedure is too time consuming and costly for routine checking. The following procedure isrecommended for this purpose.

Make at least one periodic check of the testing machine each day that it is used.

Before making the check, make at least two preliminary indentations to ensure that the test piece, indenter and anvilare seated correctly. The results of these preliminary indentations should be ignored.

Make at least one hardness indentation on a reference block with approximately the same hardness as the materialbeing tested. If the difference between mean value of the hardness readings of the test material and the hardness ofthe reference block are within the limits given in Table 2 of ISO 6506-2:1999, the machine may be regarded assatisfactory. If not, an indirect verification should be performed.
