标准摘要
[中文适用范围]： 本标准规定了道路车辆液压制动系统制动杯和密封件的性能试验；它不包括与橡胶混合物的化学成分、拉伸强度和伸长率相关的要求。 本国际标准不包括盘式制动器密封件。 本国际标准适用于使用耐高温橡胶制成的直径 60 毫米及以下的模制密封件（杯形或双唇式压盖密封件），用于道路车辆非石油基液压制动液的液压驱动缸。 符合 ISO 4925 的要求。 [外文原描述]： ISO 4928:2006 specifies performance tests of brake cups and seals for hydraulic braking systems for road vehicles; it does not include requirements relating to chemical composition, tensile strength and elongation of the rubber compound. Disc brake seals are not covered by this International Standard. ISO 4928:2006 is applicable to moulded seals (cups or double-lipped type gland seals), 60 mm in diameter and smaller, compounded from high temperature-resistant rubber, for use in hydraulic actuating cylinders using road vehicle non-petroleum base hydraulic brake fluid conforming to the requirements of ISO 4925.
英文名称Road vehicles — Elastomeric cups and seals for cylinders for hydraulic braking systems using a non-petroleum base hydraulic brake fluid (Service temperature 120 degrees C max.)
