Abstract / scope

Specifies performance tests of brake cups and seals for braking systems. Requirements relating to chemical composition, tensile strength and elongation of the rubber compound are not included. Applies to moulded seals (cups or double-lipped type gland seals), 60 mm in diameter or less, compounded from high temperatur resistant rubber. This second edition cancels and replaces the first edition (1978).
