Full Description

1.1This fire-test-response standard provides a two-step testing process for determining the effectiveness of surface applied treatments for natural Christmas trees to improve fire test response. In order for a treatment to be considered compliant with this standard, the Conditions of Acceptance of both Methods 1 and 2 are to be met.

1.2The purpose of these test methods is to:

1.2.1Utilize a detached branch test (Method 1) to screen potential surface-applied fire retardant products and to determine their effectiveness in limiting the spread of flame and the continuation of flaming by comparing the burning characteristics of treated and untreated small Christmas tree branches subjected to a small open Bunsen-burner type flame ignition source, and

1.2.2Use whole natural Christmas trees (Method 2) to determine the effectiveness of surface applied fire retardants found to be effective in the detached branch test (Method 1) through comparison of heat release rate contribution of treated trees as compared to untreated trees when subjected to an open flame ignition source.

1.3The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.4This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

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

1.6The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.

1.7This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
