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.

Meanwhile, after two days of intense and rigorous evaluation work, the evaluation team fully evaluated and affirmed the management system and testing capability of the Fire Experiment Center, and the evaluation conclusions are as follows:

After China National Accreditation Service for Conformity Assessment (CNAS) on-site review of the Fire Experiment Center of Nanjing Fire Equipment Co., Ltd, it is believed that: the quality management system of the Fire Experiment Center meets the requirements of CNAS-CL01 'Guidelines for the Accreditation of Testing and Calibration Laboratory Competence' (ISO/IEC 17025:2005), and the scope of testing capacity meets: GB25972-2010 'Gas Extinguishing Systems and Components', GB16669-2010 'Carbon Dioxide Extinguishing Systems and Components General Technical Conditions', GB5135.1-2003 'Automatic Sprinkler Systems Part 1: Sprinkler Heads', MSC/ Circ.1165-2005 'Guidelines for the approval of equivalent water-based fire extinguishing systems applied to machine premises and cargo pump compartments', MSC.1/Circ.1387 'Guidelines for the approval of stationary localized water-based fire extinguishing systems applied to class A machine premises' on-site approval of the testing capability requirements. Recommended for accreditation when the non-conformities have been rectified and confirmed on schedule.

As the certificate of the Experimental Center will expire on March 21, 2015, during which coincides with the Spring Festival, the rectification information must be submitted to China National Accreditation Service for Conformity Assessment (CNAS) before January 20, 2015 in order to ensure that a new certificate can be obtained before the expiration of the certificate and to maintain the continuity of the certificate. After the on-site evaluation, all the staff of the Experiment Center worked overtime and actively carried out rectification according to the content of non-conformities in the on-site evaluation, and submitted the rectification information to the head of the evaluation team for confirmation on January 13, 2015, and made the second modification after communicating with the head of the evaluation team and sent the rectification information to China National Accreditation Service for Conformity Assessment (CNCA) on January 15, 2015. After the submission of the information, actively maintain communication with the China National Accreditation Service for Conformity Assessment, and finally confirmed that the rectification information was passed on February 4, 2015 and archived, and on March 18, 2015 has received a new certificate of accreditation.

The successful passing of the re-accreditation and renewal of the certificate of the experiment center is of great significance to maintain the company's competitiveness and popularity, and is also of great help to the company's development of the market.
