Foreword
This instructional document has been drafted in accordance with the rules given in GB/T 1.1-2009.
This Guidance Document replaces GB /Z 22203-2008, "Reliability Test Methods for Circuit Breakers Used in Household and Similar Electrical Circuits
Law ", and GB /Z 22203-2008 The main technical changes are as follows.
--- Change the instantaneous instantaneous protection success rate and instantaneous instantaneous reliability test to short circuit protection success rate and short circuit protection reliability test
Test ", modify the success rate level value;
--- Increasing the success rate of overload protection indicators, test methods and verification test procedures;
--- Modify the test environment conditions;
--- Proposed to test the power of the detailed requirements;
--- Increased on the electric and pneumatic operation of the test device operating speed and other requirements;
--- Modify the original instantaneous protection success rate and overload protection success rate of the test sample source requirements, and strict test exit
mechanism;
--- Added Appendix B "on the household and similar places overcurrent protection circuit breaker with electrical load reliability test
Law and Procedure for Determining Reliability Data ".

Overcurrent protection circuit breakers for household and similar applications
Reliability test methods
1 Scope
This Guidance Document stipulates the reliability verification of overcurrent protection circuit breakers (hereinafter referred to as circuit breakers) for household and similar places
General requirements of the test.
This guideline applies to products that meet the requirements of GB 10963.1-2005 and GB 10963.2-2008. This instructional technique
Technical documents for the circuit breaker verification test program and test procedures, but also for product reliability testing. This instructional technical article
Pieces can be used as manufacturing enterprises to develop circuit breaker reliability indicators and test methods guidance document.
2 Normative references

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 10963.1-2005 and
GB 10963.2-2008 defined and the following terms and definitions apply to this document.
3.1.1
Failure rate
The probability of failure occurring within the unit of time after the product has worked until time t.
3.1.2
Success rate
The probability that a product fulfills a prescribed function under specified conditions or the probability of successful experimentation under specified conditions.
3.1.3
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 In this guidance document, the unit of "time" for 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.
