Question one
A group of friends asked: Now that the fuse link is turned into a self-declaration, do we need to make changes to the whole machine for filing?
Qunyou answered: No change is required, just update when the subsequent report changes.
Expert reply:
Sooner or later, it is necessary to change the CCC report of the whole machine, such as the following annual supervision and inspection to check product consistency, purchase inspection and periodic confirmation of key parts.
For an inappropriate example, there are 5 people on the account book, and one of them has his ID card changed his name. Sooner or later, the account book must be changed accordingly. Not only the account book, but also the relevant bank account, mobile phone real-name registration information, 12306 The website, etc. may have to be changed accordingly.
Question two
Group friends ask: Hello everyone, are the sterilized cutting boards and chopstick cages CCC products? I did not find it in the CCC catalog.
Qunyou answer: No, you can do voluntary certification.
Expert reply:
According to the “Announcement of the State Administration for Market Regulation on Optimizing Compulsory Product Certification Catalogue” and the annex “Description and Definition Table of Compulsory Product Certification Catalogue (Revised in 2020)” No. 18 of 2020 (see “Government Information” on the official website of CNCA for details) -"Announcement" column), sterilized cutting boards and chopstick cages are not included in the CCC product catalog.
The government is deepening reforms, and the CCC catalog is dynamically adjusted. Whether or not disinfection cutting boards and chopstick cages will be included in the CCC catalog in the future will depend on changes in the future. It is currently not in the catalog.
Question three
Qunyou asked: Is there a thermal protector between the neutral wire and the live wire of the electric heating product?
Expert reply:
Chen Zhangyu said that asking the right question is the first step in finding the answer. First, think about who is the subject of the problem, then describe your appeal clearly, and finally understand the obstacles between you and this appeal, that is, the constraints, and the problem will become clear. In fact, if you think about the question according to these three elements, the answer is likely to emerge on your own.
"Is there a thermal protector between the neutral wire and the live wire of electric heating products" is not a "good question". There is no distinction between the temperature controller for normal temperature control and the thermal circuit breaker and thermal protection for overheating protection during abnormal conditions. See the small article on "World Certification Map" "Case 19.2 A case study of whether the thermostat is also a thermostat or a thermal circuit breaker in an abnormal test action".
If the question is changed to: Should the normal temperature control device and the abnormal protection thermal circuit breaker of a product with a plug and a grounded metal sheath electric heating tube be divided into the two poles of the heating element, not on one pole? Then the answer is : High probability needs to be divided into two poles, unless if the temperature control and overheat protection device are removed, the heating element "heating ~ heat dissipation" balance will not melt.
Please refer to the 19.5 clause of GB 4706.1-2005 standard. There are small articles on the "World Certification Map" for reference: "Case 19.11.3 Relay drive transistor short circuit repeated 19.5 unqualified", "Case GB 4706.11 19.419.5 electric heating faucet can be made with Do you plug the power cord?
