NATIONAL FOREWORD
This Indian Standard (Part 1) (First Revision) which is identical to ISO 4384-1 : 2019 'Plain bearings - Hardness testing of bearing metals - Part 1: Multilayer bearings materials' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Bearings Sectional Committee and approval of the Production and General Engineering Division Council.
This standard was first published in 2000 which was identical to ISO 4384-1 : 1982. This revision has been brought out to align the standard to ISO 4384-1 : 2019.
The major changes in this revision are as follows:
a) Normative references 2 have been updated;
b) Test specimen preparation requirements have been modified;
c) Layer thickness and test conditions have been updated; and
d) Test report format has been added.
This standard is published in two parts. The other part in this series is:
Part 2 Solid materials
The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. 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 be read as 'Indian Standard'; and
b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
