Typical Fire Test Data
High-pressure laminates are subject to Flame Spread and Smoke Developed standards in structures
where codes establish such conditions.
Test data to determine compliance with these codes are obtained by the Steiner Tunnel Test method
of the American Society for Testing Materials (ASTM-E-84, Standard Test Method for Surface Burning
Characteristics of Building Materials). Tests were conducted in accordance with test method and
mounting procedure as described in paragraph X1.7.2 of the test method. This procedure is cataloged
by Underwriters Laboratories, Inc. as UL 723.
Here is typical data for Wilsonart laminates, averaged from two specific tests:
