Hydraulic component reliability assessment method
1 Scope
This standard specifies the reliability assessment method applicable to hydraulic components as defined in GB/T 17446.
a) laboratory test analysis of failure or suspension;
b) on-site data analysis;
c) Empirical test analysis.
This standard applies to the first failure of hydraulic components without maintenance.

The following terms and definitions as defined in GB/T 2900.13, GB/T 3358.1, GB/T 17446 apply to this document. For convenience
Use, some of the terms and definitions are repeated below.
3.1
Component
A separate unit that implements a hydraulic drive system function consisting of one or more parts other than piping.
Note. refers to hydraulic components such as cylinders, pumps, motors, valves, filters, etc.
3.2
Reliability
The ability of a product to perform the required function under given conditions and within a given time interval.
[GB/T 2900.13-2008, definition 191-02-06]
Note. This ability is expressed as probability, which is called reliability.
3.3
Failure failure
The ability of the component to complete the required function is interrupted.
