New "elevator floor door fire resistance test method" standard release

       National Standardization Management Committee approved on December 30, 2011 release GB/T27903-2011 the elevator door refractory testing complete, thermal insulating and heat flux measurement method ", the standard for the recommended national standards, on April 1, 2012 implementation. Since the date of the implementation of the standard, GA109-1995 "elevator floor door fire resistance test method" industry standards abolished.

New

       Elevator floor door is the door of the elevator, the fire resistance of the elevator door is very important to prevent the floor from fire through the elevator shaft. In developed countries, the structure design of the elevator floor is very attention, and it is required to have a high performance index. Our 1995 released public safety industry standard GA109 the elevator fire-proof door test method ", after 10 years of implementation, has accumulated a rich test data and practical experience, with the rose to national standards.

       GB/T27903-2011 the elevator door refractory testing complete, thermal insulating and heat flux determination method of "provisions of the terms and definitions of elevator door fire test, fire performance code and classification, test device, conditions, test piece preparation, test procedure, test results and effectiveness and test report etc.. On the basis of reference to foreign advanced standards, combined with the actual conditions of our country to determine and supplement the standard technical content, can be a comprehensive assessment of the fire resistance of various types of elevator doors.

       GB/T27903-2011 "elevator floor door fire resistance test integrity, heat insulation and heat flux measurement method" and GA109-1995 "elevator floor door fire resistance test method" compared, mainly has the following five aspects of change:

       1) increase the terms and definitions;

       2) increase the fire resistance performance code and classification;

       3) increase the test content of the performance of the elevator door, and fill up the domestic blank;

       4) the measurement of the thermal radiation from the back surface of the original test piece, and the heat flux is modified by the heat flux meter;

       5) increase the test results and the effectiveness of such content.

       The national standards by the Ministry of public security, Tianjin fire research is responsible for drafting and National Fire Standards Technical Committee building fire-resistant properties sub Technical Committee (SAC/TC113/SC8) centralized. The promulgation and implementation of this standard provides the basis for the design and production of the elevator floor. It will play an important role in improving the quality of the elevator floor, protecting the life and safety of fire fighters and people in danger.
