Z259.1-1976

Scope 1.1 This Standard defines fall arresting safety belts of the tongue buckle type and lanyards. It may be applied to an assembly consisting of a belt with an attached lanyard, or to a belt alone, or to a lanyard alone. Note: Requirements for quick-release and friction buckle types of belts are under study. 1.2 The equipment specified in this Standard is intended primarily for use by workers in the construction and mining industries, but can also be used in certain other industries where there is a danger of a fall from a height. 1.3 This Standard does not apply to special belts of harnesses, such as linemen's belts, or those used by window washers, or by workers in hazardous confined spaces. 1.4 This Standard does not cover specific designs for safety belts, except insofar as design limitations are necessary to ensure safe and durable service. 1.5 The drop test described in this Standard can be used to evaluate special accessories which may be employed in conjunction with a safety belt, but the Standard does not cover belt plus accessories as the accessories can readily be changed from one belt to another. Such accessories include safety rope grabs, connector toggles, and safety rope. 1.6 Products having materials, or forms of construction differing from those contemplated or covered by this Standard shall be considered as complying with the Standard, providing they are substantially equivalent, and meet the specified tests.
