National Foreword

This Indian Standard (Part 2) which is identical with ISO 15534-2 : 2000 ‘Ergonomic design for the safety of machinery - Part 2: Principles for determining the dimensions required for access openings’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Ergonomics Sectional Committee and approval of the Production and General Engineering Division Council.

The other parts in this series are as follows:

Part 1 Principles for determining the dimensions required for openings for whole-body access into machinery

Part 3 Anthropometric data

This standard specifies the dimension of openings for whole-body access into machinery as defined in ISO/TR 12100-1. This standard has been prepared primarily for non-mobile machinery; there may be additional specific requirements for mobile machinery.

Dimensions for access openings are based on the values for the 95th percentile, whereas reach distances are based on the values for the 5th percentile, in each case the least favorable body dimension of the expected user population being used as a basis. The same considerations apply to the location of access openings.

The anthropometric data given in Part 3 of this standard originate from static measurements of nude persons and do not take into account body movements, clothing, equipment, machinery-operating conditions or environmental conditions.

This standard shows how to combine the anthropometric data with suitable allowances to take these factors into account. It provides the dimensions to which values given in Part 3 of this standard are applicable. Value for additional space requirements are given in Annex A.

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.
