Foreword
This instructional document has been drafted in accordance with the rules given in GB/T 1.1-2009.
The guidance of technical documents instead of GB /Z 22204-2008 "overload relay reliability test methods" and GB /Z 22204-2008
The main technical changes are as follows.
--- Modify the success rate level value;
--- Modify the test conditions (see 5.1.1);
--- Proposed test power supply detailed requirements (see 5.1.3);
--- Added Appendix C "on the overload relay auxiliary contact reliability test methods with electrical load conditions and to determine the reliability
Data steps. "
This guidance document is proposed by China Electrical Equipment Industry Association.

3 Terms and definitions, symbols
3.1 Terms and definitions
GB/T 2900.13-2008, GB/T 2900.18-2008, GB/T 5080 (all parts), GB 14048.1-2012,
GB 14048.4-2010 and GB 14048.6-2008 as defined by the following terms and definitions apply to this document.
3.1.1
Success rate
The probability that a product fulfills a prescribed function under specified conditions or the probability of successful experimentation under specified conditions.
3.1.2
Timing or censoring protocols timeorfailcurtailedtestplan
During the test, the test sample is monitored continuously or at short intervals. If the cumulative test-related time reaches the predetermined test cut-off
, And the number of related failures does not reach the predetermined number of truncated failures, the decision is received; if the cumulative correlation test time does not reach the predetermined test censorship
Time, and the number of related failures reaches a predetermined number of truncated failures, the sentence is rejected.
NOTE The "units of time" in this guidance document related to the magnitude of reliability may be replaced by the "number of times", for example, the number of relevant tests accumulated, the number of relevant tests
Number, number of censored, the number of deadlines and the number of tests.
3.1.3
Relevant failure (Relevant failure)
Failure must be accounted for in interpreting the results of a test or work or in calculating the magnitude of reliability.
