IS 19184 : Part 2 : 2025/ISO 10071-2 : 2005 Tools for Pressing - Ball-Lock Punches - Part 2 Ball-Lock Punches for Heavy Duty
NATIONAL FOREWORD
This Indian Standard (Part 2) which is identical to ISO 10071-2 : 2005 'Tools for pressing - Ball-lock punches - Part 2: Ball-lock punches for heavy duty' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Metal Forming Machines Sectional Committee and approval of the Production and General Engineering Division Council.
This part of standard specifies interchangeable dimensions and tolerances, in millimetres, for ball-lock punches for heavy duty. It is applicable to ball-lock punches with shank diameter sizes from 10 mm up to including 40 mm, in round, square, rectangular and oblong shapes, for punching holes in steel sheets or other materials the thickness of which is less than 8 mm.
This Indian Standard is published in two parts. The other part in this series is:
Part 1 Light duty
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.
