Scope

GB/T 36375-2018 is the English-translated version of 轨道交通一系橡胶弹簧通用技术条件.

GB/T 36375-2018 gives the general technical requirements for primary suspension rubber springs used on rail transit vehicles, in particular conical springs and V-shaped springs.

It defines the terms, symbols, classification and coordinate system used to describe these springs, such as static creep, and sets the operating ambient temperature.

Its technical requirements cover size and appearance, materials and product performance, each matched by a test method, from material tests on the rubber to performance tests on the finished spring.

It also lays down factory and type inspection with the decision rules, and the marking, packaging, transport and storage of the springs. It serves their design, manufacture and inspection, and other types of spring may use it as a reference. It was issued on 7 June 2018 and has applied since 1 January 2019.
