Standard: NEMA Standards Publication LD 3.10 – Radiant Heat Resistance

Certification Required: N/A

Scope: Per NEMA LD 3.10: "This test measures the ability of the surface of high-pressure decorative laminate to resist damage when subjected to a radiant heat source."

Applicable Products: High-pressure decorative laminate

Test Procedure: The heater is positioned on the test specimen with the resistance coil at least 1.5 in. from any edge. The timer is started at the same time and the assembly is covered with the enclosure. The test is continued until the specimen fails or a time of 600 sec. is reached. Failure is categorized as blistering, charring, permanent discoloration, or crazing. The procedure is repeated two additional times one on the specimen surface which is at least 4 in. from the other tests.

End Result: This test results in the radiant heat resistance, which is the time to failure for each specimen.
