5.1 This test method addresses the suitability of deck materials by assessing their response to fire hazards associated with sources of flame located beneath the deck material.

1.1 This standard prescribes a method to assess the fire-test response characteristics of deck materials when used as the walking surface of a deck. The prescribed fire exposure is intended, under test conditions, to determine the heat release rate and the thermal decomposition modes of decking materials when exposed to a burner flame simulating combustibles burning beneath a deck.²

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems has the potential to result in non-conformance with the standard.

1.3 This standard is used to measure and describe the response of deck materials to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the deck materials under actual fire conditions.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1.5 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.
