At the beginning of 2014, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China, the Ministry of Public Security, and the National Certification and Accreditation Administration jointly issued the 'Announcement on Implementing Compulsory Product Certification for Some Fire Protection Products', which decided to implement mandatory product certification for some fire protection products and listed a mandatory product certification catalog. Starting from September 1, 2015, all fire protection products listed in the catalog did not obtain mandatory product certification certificates or were not labeled with mandatory product certification marks, It shall not be manufactured, sold, imported, or used in other business activities. Our company's seven major categories of gas fire extinguishing products, including heptafluoropropane fire extinguishing equipment, IG541 gas fire extinguishing equipment, high-pressure carbon dioxide fire extinguishing equipment, and cabinet type heptafluoropropane gas fire extinguishing devices, are all included in this catalog, involving a total of 11 type inspection reports.

Gas fire extinguishing equipment is one of our company's main products, and obtaining a certificate before September 1, 2015 will directly affect the production and sales of our gas products. Therefore, since the beginning of 2015, the company has made thorough arrangements for the CCC certification of gas fire extinguishing equipment and established a CCC certification working group led by the general manager. The working group immediately formulated a detailed and meticulous work plan, which is mainly divided into three stages: report confirmation, preparation before factory inspection, and factory inspection. The content includes a series of tasks such as drawing and sample preparation, filling out the characteristic document table, main classification table, and model comparison table, submitting non-conforming items for inspection, confirming the original report and issuing a new one, applying for certification, organizing and uploading documents, and improving the process documents and equipment configuration in accordance with the certification rules.

After months of joint efforts from various departments of the company, the working group overcame numerous obstacles and difficulties that were difficult to predict during the certification preparation process. Finally, on August 28th, a 16 person inspection working group consisting of the Fire Product Qualification Evaluation Center of the Ministry of Public Security and the National Fixed Fire Extinguishing System and Refractory Component Quality Supervision and Inspection Center was welcomed, Our company has also been recommended by the National Center for Quality Supervision and Inspection of Fixed Fire Extinguishing Systems and Refractory Components as a pilot enterprise for 3C certification factory inspection of gas fire extinguishing equipment. After two days of careful, meticulous, and rigorous inspection by the inspection team of our company's quality system documents, design and development documents, drawings, processes, procurement control, process control, routine inspection confirmation inspection procedures, records, equipment configuration and operation, witness testing, product consistency inspection, and other aspects, it was ultimately decided that we unanimously recommend our company to pass the CCC certification inspection of gas fire extinguishing equipment, The evaluation center has approved our company's CCC certification certificate for gas fire extinguishing equipment on August 31st. Through the review of our company, the inspection team has established a new positioning for the CCC certification inspection standards for gas fire extinguishing equipment, and has also provided a new basis for the inspection of other related enterprises.

Project Overview:

Xiamen Rail Transit Line 1 generally runs in a north-south direction, connecting important clusters such as Siming District, Huli District, and Jimei District. It is a backbone line radiating northward from this island to form a cross sea fast connection channel. Metro Line 1 is a north-south skeleton line, constructing a fast cross sea connection channel between the island and the Jimei area, and serving train stations inside and outside the island.

As the backbone line of Xiamen's rail transit network, Metro Line 1 is constructed along the important north-south development axis of the city, starting from Zhenhai Road and passing through Wenyuan Road, Hubin Middle Road, Hubin South Road, and Jiahe Road to exit the island; At the Gaoji seawall and Jixing seawall, they protrude above the ground and cross the sea in an elevated and aboveground manner; After crossing the sea, it 'drilled' into the underground again, along Xingjin Road, Chengyi Street, and the planned Hengshan Road, and finally reached the North Square of Xiamen North Station. The total length of Metro Line 1 is 30.3 kilometers. According to the design, Xiamen Metro Line 1 uses standard B-type air-conditioned vehicles in a six car formation, capable of carrying approximately 1400 passengers, with a total travel time of approximately 50 minutes.

There are a total of 24 stations set up on Metro Line 1, except for elevated stations in the cross sea section, all of which are underground stations. The average distance between stations is 1.3km. Among them, 14 stations are set up on the island, with an average distance between stations of 1.0km; One station is set up in the cross sea section, with an average distance between stations of 3.3km; There are 9 stations set up outside the island, with an average distance between stations of 1.4km. There are a total of 7 transfer stations in all stations. The line is set up with a Takasaki parking lot in the northern part of the island, and a Qigou comprehensive maintenance base is set up north of Jimei New City. Two main substations and one control center are set up along the entire line.

Xiamen Metro Line 1 is expected to be completed and put into trial operation in 2018.

The gas fire extinguishing room provided by Nanxiao Group for testing is currently the largest protected area among the physical fire extinguishing test rooms in China, with a size of 18X8X5.9 meters. The test room is built in the large space test site of the Fire Test Center of Nanxiao Group, using a brick concrete structure that is completely built according to the size and structure of the protected area in the subway project. Its fire prevention and pressure resistance requirements can fully meet the requirements of the open fire test of the project.

The fire extinguishing test was conducted on the morning of May 7, 2015, with the joint participation and witness of the owner, design, consulting, supervision, and testing center. The fire extinguishing test was monitored and recorded in real-time according to the test outline.

The experiment was conducted according to two plans.

Option 1: Verified whether a fire under the floor can trigger a detector alarm, and recorded data. The experimental results indicate that setting detectors under the floor can also ensure that the alarm control system can alarm and interlock normally.

Option 2: Conduct a total flooding fire extinguishing system test on the protected area. A total of 10 ignition points were set in the test, and ignition oil tanks were installed in the upper four corners of the protected area and the lower four corners of the protected area. An ignition oil pan was set below the floor, and an ignition oil pan was set above the floor. The system control mode is fully automatic control, which is automatically controlled and linked by the alarm control system after ignition. One minute after ignition, the fire extinguishing system starts, and within a short period of 50 seconds, the fire extinguishing system completely extinguishes 10 ignition points.

The smooth progress of test plans 1 and 2 has been unanimously recognized by all parties. Experts say that the design is reasonable, the fire extinguishing test plan is complete, the test implementation is feasible, and the fire extinguishing effect is perfect. This IG541 gas fire extinguishing physical test has played a very good guiding role in the fire extinguishing application of domestic gas fire extinguishing systems in subway and other fire engineering projects.
