ICS 01.100.40 PGD 22
Reaffirmed 2022


This Indian Standard which is identical with IS0 9962-2 : 1992 ‘Manually operated draughting machines - Part 2 Characteristics, performance inspection and marking’, issued by International Organization for Standardization (ISO), was adopted by the Bureau of Indian Standards on the recommendation of the Optical and Mathematical instruments Sectional Committee (LM 20) and approval of Light Mechanical Engineering Division Council, The standard is being published in following three pans:

Part 1 Definitions, classification and designation;

Part 2 Characteristics, performance, inspection and marking; and

Part 3 Dimensions of scale rule chuck plates (under preparation).

The requirements of draughting machine were earlier covered in IS 2287 : 1970 ‘Specification for drafting machines (first revision)’ which will be withdrawn after publication of all three parts.

IS 2287 : 1970 was also covering the certification of draughting machines which will now be covered by part 2 of IS/ISO 9962-2 : 1992.

The text of ISO Standard has been approved as suitable for publication as 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 (J has been used as a decimal marker while in Indian Standards the current practice is to use a point (.) as the decimal marker.
