The establishment and maintenance of the production quality management system of explosion-proof products is very important to ensure the compliance of the explosion-proof products produced. in this regard
In terms of standardization, my country adopted ISO /IEC 80079-34 to formulate GB/T 3836.21-2017 in.2017.
On the basis of GB/T 19001-2008 (ISO 9001.2008), supplementary requirements and suggestions are put forward for the production of explosion-proof products. Then, make
The GB/T 19000 (ISO 9000) and GB/T 19001 (ISO 9001) of the quality system basic standards have been revised, in terms of content and structure
There are relatively large changes. Internationally, IEC released ISO /IEC 80079-34 on the basis of ISO 9001.2016 in.2018.
In.2018, its main technical content can also be applied to the situation in my country, in order to coordinate with the quality system stipulated in GB/T 19000 and GB/T 19001
Consistent with the development of international standards, GB/T 3836.21 needs to be revised.
On the basis of adopting the main content of ISO /IEC 80079-34.2018, this revision has made appropriate modifications to adapt to the specific requirements of our country.
