CQM10-C2301-2024 Detailed rules for implementation of compulsory product certification - Explosion-proof electrical products English, Anglais, Englisch, Inglés, えいご
1. Application scope
The Detailed Rules is applicable to Classes I, II and III explosion-proof electrical products, including the following categories: explosion-proof motors; explosion-proof electric pumps; explosion-proof power distribution equipment; explosion-proof switches, and control and protection products; explosion-proof starters; explosion-proof transformers; explosion-proof electric actuators and solenoid valves; explosion-proof plug devices; explosion-proof monitoring products; explosion-proof communication and signaling devices; explosion-proof air conditioning and ventilation equipment; explosion-proof electric heating products; explosion-proof accessories and Ex components; explosion-proof instruments; explosion-proof sensors; safety barrier products; explosion-proof instrument boxes; and explosion-proof lamps and control devices.
Any adjustment to the application scope caused by any change(s) in laws and regulations, related product standards, technologies, industrial polices and other factors shall be subject to the announcement issued by the CNCA and relevant TC resolutions.
2. Applicable standards for certification
Explosion-proof electrical products (see Table 1) shall be certified according to the standards applicable to their types of protection. The types of explosion protection of products may be one of or a combination of the following.
.....
.....
In principle, the current valid versions of the above standards issued by the national standardization administrative department shall apply. In case of any revision to the above standards, the requirements of the documents on them issued by the CNCA shall prevail.
3. Certification mode
Certification mode is a combination of a series of links and elements to certify the products to be certified. The mode for compulsory certification of explosion-proof electrical products is as follows:
Type test + initial factory inspection + post-certification supervision
The aforesaid post-certification supervision refers to one or combination of two methods: the post-certification follow-up inspection and sample testing and/or inspection on production site.
For a small quantity of explosion-proof electrical products delivered/imported in a single batch, the following alternative certification mode is also available:
Type test + 100% inspection
A small quantity of explosion-proof electrical products delivered/imported in a single batch refers to those with a quantity of no more than 5 units (sets) in the same batch, for which a sales contract has been signed specifying the sales destination, customer, and product model, and which are manufactured using the same raw materials and under identical production conditions.
4. Certification unit division
In principle, the application units shall be divided according to the equipment classification, types of explosion protection, product categories, explosion-proof structure, safety
