ISO 6117:2005规定了用于鼓式车轮制动缸端盖的模制橡胶防尘套的性能试验；这些防尘套可防止灰尘和湿气进入，这些灰尘和湿气可能会导致腐蚀，否则会影响车轮制动器的操作。 它适用于普通和加强件插入类型的护套，用于使用符合ISO 4925的流体安装在轮缸中。不包括与橡胶化合物的化学成分、抗拉强度或制动伸长率有关的要求；它不包括插入式橡胶与钢筋的粘合强度。 这些靴子中使用的橡胶材料适合在以下温度范围内使用:- 40°C至+100°C。

ISO 6117:2005 specifies performance tests for moulded rubber boots used at end closures on drum type wheel brake cylinders; these boots prevent the entrance of dirt and moisture which could cause corrosion and otherwise impair wheel brake operation. It is applicable to boots of both plain and reinforcement insert types, for fitting in wheel cylinders using a fluid in accordance with ISO 4925. It does not include requirements relating to chemical composition, tensile strength or elongation at brake of the rubber compound; it dose not cover the strength of adhesion of rubber to the reinforcement in the insert type. The rubber material used in these boots is suitable for operation in a temperature range of -40 °C to +100 °C.
