Handle the fire test report of building materials and the quality inspection report of fire resistance of materials.
In order to ensure the safety of buildings, many countries and regions require fire protection testing of building materials and issue corresponding fire prevention inspection reports. At the same time, for some specific types of building materials, it is also necessary to carry out a quality inspection report on fire resistance.
1. Handle the fire prevention test report of building materials.
1.Purpose of detection.
The purpose of fire detection of building materials is to evaluate the combustion performance and fire resistance limit of building materials in fire, so as to provide a scientific basis for the design and construction of buildings.
2.Testing criteria.
According to the standards of different countries and regions, different standards and methods are used for fire detection of building materials. In China, commonly used testing standards include GB T 14402-2007 "Classification of Combustion Performance of Building Materials and Products" and GB 8624-2012 "Classification of Combustion Performance of Building Materials and Products".
2. Quality inspection report of material fire resistance.
1.Purpose of detection.
The quality inspection report of the fire resistance of the material is to evaluate the stability and durability of the material at high temperatures, so as to provide a reference for the fire protection design and construction of the building.
2.Detection method.
The quality inspection report of the fire resistance of the material is usually tested by the following methods:
1) Fire resistance limit test: By simulating the fire scene, the material is exposed to high temperature, and its deformation, cracking, falling off and other changes are observed, so as to determine its fire resistance limit.
2) Combustion test: Evaluate the combustion performance of the material by igniting it and observing its combustion behavior, including combustion speed, flame height, flue gas composition, etc.
3) Thermal stability test: By treating the material at high temperature and observing its performance changes, including strength, hardness, color, etc., so as to evaluate its stability at high temperature.
3.Inspection process.
1) Choose the right testing institution: According to the region and specific needs, choose a testing institution with corresponding qualifications and experience.
2) Prepare samples: prepare samples according to the requirements of the testing institution, and ensure the representativeness and consistency of the samples.
3) Testing: Send the sample to the testing institution for fire resistance testing.
4) Issue a report: The testing agency will issue a corresponding fire resistance quality inspection report according to the test results.
