Scope

GB/T 38206.1-2019 is the English-translated version of 气动元件可靠性评估方法第1部分：一般程序.

GB/T 38206.1-2019 is the Chinese standard "Methods to assess the reliability of pneumatic components -- Part 1: General procedures". Its scope clause reads: This part of GB/T 38206 specifies the general procedures, general test conditions, calculation methods, and numbers used to evaluate the reliability of pneumatic components.

According to the evaluation method and the preparation requirements of the test report. These procedures and methods are independent of the type of component and the design itself.

Note 1. The service life of components is affected by many variables, so statistical analysis is needed to illustrate the test results. This section applies to the first failure of pneumatic components without maintenance.

Note 2. Refer to Appendix A for the treatment method when the first time the abnormal value occurs. Its clauses include terms and definitions.
