ISO 4344

ISO 4344:2004 specifies the minimum requirements for the manufacture and testing of stranded carbon steel wire ropes used for suspension duty on traction drive and roped hydraulic lifts and for compensation and governor duties on passenger and freight lifts, dumbwaiters, personnel hoists and man lifts moving between guides. It gives the minimum breaking forces for the more common sizes, rope grades and rope classes and constructions. It is applicable to ropes made from bright and galvanized wire finish in various constructions from 6 mm to 38 mm diameter supplied as bulk manufacture and manufactured after its publication date. It is not applicable to ropes for builder's hoists and temporary hoists not running between permanent guides -- whether passenger carrying or not -- or to ropes for cableways.
