Doc No.: PGD 35(13448) IS XXXX: 2019 ISO 11090-2:2014 Machine Tools, Machine Tool Elements and Holding Devices Sectional Committee, PGD 35 NATIONAL FOREWORD This Indian Standard (Part 2) which is identical with ISO 11090-2:2014 Test conditions for die sinking electro-discharge machine (die sinking EDM) Testing of the accuracy Part 2: Double-column machines (slide-head type) 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 Single-column machines (cross-slide table type and fixed table type) 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 certain International Standards for which Indian Standards also exist. The corresponding Indian Standards, which are to be substituted in their respective places, are listed below along with their degree of equivalence for the editions indicated International Standard Corresponding Indian Standard Degree of Equivalence ISO 230-1 : 2012 Test code for machine tools Part 1: Geometric accuracy of machines operating under no-load or quasi-static conditions ISO 230-2 : 2014 Test code for machine tools Part 2: Determination of accuracy and repeatability of positioning of numerically controlled axes IS 2063 (Part 1) : 2016 Test Code for Machine Tools Part 1 Geometric Accuracy of Machines Operating Under No-load or Quasi-Static Conditions ( Third Revision ) IS 2063 (Part 2) : 2016 Test Code for Machine Tools Part 2 Determination of Accuracy and Repeatability of Positioning of Numerically Controlled Axes ( First Revision ) Identical Identical
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.
