Chapter 10, Chapter 11, Chapter 16, Chapter 17, Chapter 18, Article 21.2, Chapter 23 and Chapter 24 of this part are mandatory, and the rest of the contents are recommended. This part is the fourth standard in the GB16915 "Switches for household and similar fixed electrical installations" series of standards. The structure and name of this series of standards are as follows:

Switches for household and similar fixed electrical installations Part 2: Particular requirements Switches for household and similar fixed electrical installations Part 2: Particular requirements Section 3: Extension IEC60669-2-3:1997 is used in conjunction with IEC60669-1:1993 (2nd edition). Due to the accelerated revision of IEC standards, the national standard GB16915.1-2003 has been revised according to IEC60669-1:2000 (Edition 3.1), so there is a problem of using different versions. In order to make the supporting use of the series of standards more complete and reasonable, this part is based on IEC60669-1:2000 and modified to adopt IEC60669-2-3:1997
This part does not yet include specific requirements for non-reset delay switches (mostly electronic). For the assessment of non-reset delay switches, the requirements of this part and the applicable requirements in GB16915.2 can be temporarily adopted according to the requirements in the notes of Chapter 1 of this part. The main differences between this part and IEC60669-2-3:1997 are as follows: 1. Considering that this part is used in conjunction with GB16915.1-2003, the titles of each chapter are as consistent as possible with the general requirements of switches. Therefore, the title of Chapter 14 "Mechanism" is changed to "Switch Mechanism"; the title of Chapter 15 "Aging resistance, protection against harmful water ingress and moisture resistance" is changed to "Aging resistance, protection provided by switch housing and moisture resistance".
2. After verification, the contents of Articles 3.14 and 3.15 in the IEC original text are incorrect, and should be 3.17 and 3.18. The first paragraph of Article 3.7.1.1 "See Figure 1 of GB16915.1" is changed to "See Figure 8 of GB16915.1". "Table 13" in Article 4.16.2 is changed to "Table 14". "Table 16" in the sixth paragraph of Article 5.19.1 is changed to "Table 17". 6. At present, there are products with delay time less than 1min for time delay switches. This part does not have test methods for such products. Therefore, in order to expand the coverage, the following content is added after 19.103: TDS with delay time less than 1min shall be tested as follows: For TDS with adjustable delay time, the delay time shall be adjusted to the longest delay time, and the time difference between the first start and the second start shall be 2/3 of the delay time.
The total delay time shall be: the delay time declared by the manufacturer, ±5% of the delay time plus the time difference between the two starts. In the second paragraph of Chapter 7.23, "Table 19" is changed to "Table 20". In the first item of the fifth paragraph of Chapter 8.101, "\GB16915.1 Figure 1" is changed to "\GB4208 Figure 1". "GB16915.1 Table 13" is changed to "GB16915.1 Table 14".
This part should be used in conjunction with GB16915.1-2003 "Switches for household and similar fixed electrical installations Part 1: General requirements".
