ASTM E108 Roof Coverings - Product Scope:

Applicable to various types of roof coverings, such as photovoltaic panels, carport roof covers, asphalt shingles, built-up roofing, fire-retardant treated wood shingles and shakes, and other common roofing materials, including components installed on roofs like photovoltaic panels.

ASTM E108 Standard Test Methods for Fire Tests of Roof Coverings

ASTM E108 Standard Test Methods for Fire Tests of Roof Coverings

Depending on the product's use and flame resistance requirements, the corresponding class can be selected for application:

Class A tests apply to the following roof coverings: expected to effectively resist severe fire exposure, afford a high degree of fire protection to the roof deck, do not slip from position, and are not expected to produce a flying brand hazard.

Class B tests apply to the following roof coverings: expected to effectively resist moderate fire exposure, afford a moderate degree of fire protection to the roof deck, do not slip from position, and are not expected to produce a flying brand hazard.

Class C tests apply to the following roof coverings: expected to effectively resist light fire exposure, afford a light degree of fire protection to the roof deck, do not slip from position, and are not expected to produce a flying brand hazard.

Note: Class A is the highest, followed by Class B and Class C; generally, applying for Class C is sufficient for conventional products.

Process for Applying for ASTM E108 Flame Spread Test:

1.Identify the product - photovoltaic panels, and fill out the application form.

2.Determine the test method to be performed, such as the flame spread test.

3.Prepare samples according to standard requirements, e.g., Class C samples require 2.4x 2 pieces.

4.Submit samples for testing.

5.After testing is completed, issue the test report.
