Doc No.:13(13353) IS XXXX: 2019 ISO 15243 : 2017 Bearing Sectional Committee, PGD 13 NATIONAL FOREWORD This Indian Standard which is identical with ISO 15243 Rolling bearings Damage and failures Terms, characteristics and causes issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Bearing Sectional Committee, PGD 13 and approval of the Production and General Engineering Division Council. 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. 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. In this adopted standard, reference appears to the following International Standard for which Indian Standard also exists. The corresponding Indian Standard which is to be substituted in its place is listed below along with its degree of equivalence for the edition indicated. International Standard Corresponding Indian Standard Degree of Equivalence ISO 5593 Rolling bearings Vocabulary PGD 13 (13309) Rolling bearings Vocabulary Identical to ISO 5593: 1997 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 accordance with IS 2:1960 Rules for rounding off numerical values (revised). The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.
