Specifies minimum access openings for hand, head, body, arm reach and two-handed reach. Provides information so that access openings in equipment and machinery are made large enough for the intended function. Larger openings are given for access with arctic clothing in cold environments. The recommended openings are the smallest that will accommodate 95 percent of the worldwide operator population.

This International Standard specifies the minimum access openings on earth-moving machinery for1) the hand, 2) the head, 3) the body, 4) arm reach, 5) two-handed reach. It provides engineers and designers with information in order that access openings provided in equipment and machinery for purposes of inspection, adjustment and maintenance are made large enough for the intended function by the man in the field or shop.The larger openings for access with arctic clothing are for construction equipment intended for use in cold environments. Based on available anthropometric data, the recommended openings are the smallest that will accommodate 95% of the worldwide operator population.In most cases openings larger than the recommended minimum will be more useful and allow greater efficiency.
