Scope

This Part specifies five dimensions required for openings (minimum opening
dimensions, please refer to Bibliography [2]) for whole-body access into machinery
(please refer to 3.1 in GB/T 15706.1-1995), and eleven formulas for the calculation of
opening dimension which combine anthropometric data (human body dimension) and
additional space (allowances).
Please refer to Table 1 in GB/T 18717.3-2002 for anthropometric data. Please refer to
Appendix A in this Part for the numerical value of additional space.
Dimensions for passages are based on the values for either the 95th or the 99th
percentiles of the expected user population (please refer to 3.1 in Bibliography [2]).
Values for the 99th percentile apply to emergency egress routes.
The anthropometric data given in GB/T 18717.3-2002 originates from static
measurements of nude persons, and do not take into account body movements,
clothing, equipment, machinery-operating conditions or environmental conditions.
This Part is applicable to non-mobile machinery. In terms of mobile machinery, there
may be additional specific requirements.
Situations where people are to be prevented from reaching a hazard are elaborated in
GB 12265.1.
