IS 8165 : 2010/ISO 5734 : 1986 ACCEPTANCE CONDITIONS OF MECHANICAL DIVIDING HEADS FOR MACHINE TOOLS — TESTING OF ACCURACY
Reaffirmed 2023
NATIONAL FOREWORD
This Indian Standard (First Revision) which is identical with ISO 5734 : 1986 ‘Acceptance conditions of mechanical dividing heads for machine tools — Testing of accuracy’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Machine Tools Sectional Committee and approval of the Production and General Engineering Division Council.
This standard was first published in 1976. The first revision has been taken up to align with the latest ISO Standard.
The text of the 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.
c) Some dimensions appears in ‘inches’ in the International Standard besides in metric systems, while in Indian Standards, the current practice is to give metric values only.
