Description of "3C" for external storage pressure (backup pressure type) HFC-227ea fire extinguishing system

In the pipe network gas fire extinguishing, it is difficult to distinguish the integral number of external storage pressure (standby pressure type) HFC-227ea fire extinguishing system and internal storage pressure (ordinary) HFC-227ea system. Today, we will clarify it for you.

1. Up to now, there is no national standard for HFC-227ea fire extinguishing system of external storage pressure, only enterprise standard, and the standard implemented is GB25972-2010< Gas Fire Extinguishing System and Components "; Q/RXF 1-2014 "External Pressure HFC-227ea Fire Extinguishing System", evaluation basis: "Technical Evaluation Work Specification for Fire Products", so now the certificate of HFC-227ea fire extinguishing system with external pressure is: Technical evaluation certificate and inspection report of fire products, so there is only one 3C label for the system, and we have the one affixed on the cylinder. (Information about the certificate can be found on www.cccf.com.cn)

2. The certification process of HFC-227EA external pressure storage fire extinguishing system: ① the manufacturer sends samples to the "National Quality Supervision and Inspection Center for Fixed Fire Extinguishing System and Fire-resistant Construction" →② Obtain the "type test report" →③ Apply for technical appraisal to the "Fire Products Qualification Assessment Center of the Ministry of Public Security" →④ factory review →⑤ obtain the "Technical Appraisal Certificate". The above process is strictly in accordance with the relevant national laws and regulations!

"Technical Appraisal Certificate" and "Type Test Report" are issued as "system", not as "component". The external pressure storage system produced by our company is composed of several components. The "Certificate of conformity" issued to the system already includes a commitment to the quality of its components. It is no longer necessary to issue separate duplicate certificates of conformity for "components". In addition, there is no documented requirement that the "components" of external storage pressure HFC-227ea fire extinguishing system be certified.

3. The internal storage pressure (ordinary) HFC-2propane system has national standards, so the certificate issued is 3C certificate.
