Doc No.: PGD 35(13458) IS XXXX: 2019 ISO 15616-3:2003 Machine Tools, Machine Tool Elements and Holding Devices Sectional Committee, PGD 35 NATIONAL FOREWORD This Indian Standard (Part 3) which is identical with ISO 15616-3:2003 Acceptance tests for CO2-laser beam machines for high quality welding and cutting Part 3: Calibration of instruments for measurement of gas flow and pressure issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Machine Tools, Machine Tool Elements and Holding Devices Sectional Committee, PGD 35 and approval of the Production and General Engineering Division Council. Other parts in this series are: Part 1 Part 2 Part 4 General principles, acceptance conditions Measurement of static and dynamic accuracy Machines with 2-D moving optics 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 EN ISO 15616-1:2003 Acceptance tests for CO2-laser beam machines for high quality welding and cutting Part 1: General principles, acceptance conditions (ISO 15616-1:2003) PGD 35 (13456) Acceptance tests for CO2-laser beam machines for high quality welding and cutting Part 1: General principles, acceptance conditions Identical In reporting the result of a test or analysis made in accordance with this standard, if the final value, observed or calculated, is to be rounded off, it shall be done in accordance with IS 2 : 1960 Rules for rounding off numerical values (revised).
