NATIONAL FOREWORD

This Indian Standard (Part 1) which is identical with ISO 4384-1:1982 ‘Plain bearings — Hardnesstesting of bearing metals — Part 1: Compound materials’ issued by the International Organization forStandardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of thePlain Bearings Sectional Committee and approval of the Light Mechanical Engineering Division Coun-cil.

This standard is being published in two parts. The other part of the standard is:

IS 14802 (Part 2) :2000 Plain bearings — Hardness testing of bearing metals: Part 2 Solidmaterials

The text of ISO standard has been approved as suitable for publication as Indian Standard withoutdeviations. Certain conventions are, however, not identical to those used in Indian Standards.Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should beread 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 the adopted standard, reference appears to certain International Standards for which IndianStandards also exist. The corresponding Indian Standards which are to be substituted in their place arelisted below along with their degree of equivalence for the editions indicated:

For the purpose of deciding whether a particular requirement of this standard is complied with, the finalvalue, observed or calculated, expressing the result of test or analysis, shall be rounded off in accord-ance with IS 2 :1960 ‘Rules for rounding off numerical values (revised)’. The number of significantplaces retained in the rounded off value should be the same as that of the specified value in thisstandard.

PLAIN BEARINGS — HARDNESS TESTING OFBEARING METALS

PART 1 COMPOUND MATERIALS

1 Scope and field of application

This International Standard specifies parameters for the hard-ness testing of compound materials for plain bearings madefrom steel and bearing metal with bearing metals based onlead, tin, copper, and aluminium, manufactured by casting,sintering, or plating. It represents a supplement to the existingISO publications on hardness testing and therefore includesonly the extensions and restrictions to be observed as com-pared to those publications.

The measuring method applied depends on the bearing metallayer thickness, its hardness and its structure.

Owing to the heterogeneous structural composition of the ma-jority of these bearing metals, a Brinell test is to be preferred.The Vickers measurement should be used in the case of verysmall layer thicknesses.

The surface of the specimen in the test area shall be metallicbright and conditioned in such a way that a satisfactorymeasurement of the test impression is possible. During thepreparation of the specimens, it shall be ensured that thematerial is not heated.

The test surface may be plane or curved. ISO 409/1 includescorrection factors for cylindrical surfaces.
