How to apply for ASTM E108 flame retardant test for photovoltaic panels?

ASTM E 108 It is a fire retardant performance test for building roof coverings , To apply for this test , First, determine the level of execution , Different levels of classification , The sample specification is different from the test method .

ASTM E108 Flame retardant test - Standard full name ：

ASTM E108 Standard Test Methods for Fire Tests of Roof Coverings

ASTM E108 Standard Test Method for fire test of roof coverings

The scope of application of fire test of three levels of classification ：

A The class a test applies to the following roof coverings ： It is expected to effectively resist serious fires , Provide a high degree of fire protection for the roof deck , Will not fall from position , It is not expected to cause flying fire hazard .

B The class a test is applicable to those who are expected to effectively resist moderate fire exposure 、 Provide moderate fire protection to the roof deck 、 Roof coverings that do not slip from position and do not pose a fire hazard .

C The class a test is applicable to the test that can effectively resist mild fire 、 Provide light fire protection for the roof deck 、 Roof coverings that do not slip from position and are not expected to cause a fire hazard .

Because the three level test methods are different from the scope of application , So you need to confirm the level you want to apply for before the test .
