ASTM E162: Radiant Heat Surface Flammability Testing Services
ASTM E162 standard is used to determine and give details of the response of materials, products, or assemblies to heat and flame under controlled conditions. But under actual fire conditions, it does not incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies by itself.

What Is ASTM E162 Radiant Heat Surface Flammability?
ASTM E162 provides a test method for evaluating the surface flammability of materials when exposed to a radiant heat energy source. The test measures how easily a material ignites and how flame spreads across its surface under controlled conditions.
This standard is widely used in building, transportation, and materials industries to assess fire performance and ensure safety compliance.
Applications and Benefits of ASTM E162 Radiant Heat Surface Flammability Testing
Scope
ASTM E162 focuses on determining the flammability characteristics of materials by measuring flame spread and heat release when exposed to radiant heat. It provides a comparative evaluation of fire performance.
The test evaluates:

ASTM E162 Radiant Heat Surface Flammability FAQs
ASTM E162 is a standard test method used to evaluate surface flammability of materials using a radiant heat energy source, measuring flame spread and heat release characteristics.
ASTM E162 is important because it helps determine how materials behave under fire exposure, supporting safety compliance in building, transportation, and industrial applications where fire risk is critical.
ASTM E162 exposes a material to radiant heat and ignition source, then measures flame spread rate and heat release to evaluate flammability characteristics.
ASTM E162 requires a radiant panel apparatus, ignition source, specimen holder, and measurement instruments to record flame spread and heat release parameters.
Results are reported as flame spread index and heat release parameters, indicating material flammability and helping determine compliance with fire safety standards.
