Building Materials Flame Retardant Tester Large Plate Method GB12441-2018 Standard

Building materials flame retardant coating testing machine (large plate method)

Introduction:

The flame retardant coating testing machine (large plate method) is used to place the fire retardant coating coated on the surface of the combustible substrate in the flame under specified conditions in accordance with the technical indicators and requirements specified in the national standard GB 12441-2018 to test its flame retardant time and flame retardant performance, so as to judge the fire retardant effect of the coating and determine whether it meets the relevant standards.

Main usage:

       Evaluating the performance of fire retardant coatings:

The large panel method can be used to evaluate the flame retardant properties of fire retardant coating, so as to determine whether they are suitable for fire protection of specific buildings.

       Product quality control:
In the production and sales process of fire retardant coatings, the large panel method can be used as a quality control method to ensure product quality.

      Scientific research and development:

The large panel method can also be used for scientific research and development of fire retardant coatings, such as exploring new materials and new processes, and evaluating their performance.
