ASTM E3082-17e1

4.1 In past research experiments, some surface applied fire retardant chemicals improved the fire performance characteristics of natural Christmas trees, whereas other retardants were not effective, or adversely affected tree quality or burning characteristics. These methods are intended to provide a two-step process to determine the effectiveness of surface applied treatments to natural Christmas trees.

4.2 The fire performance of natural trees is highly variable and varies from species to species. Test results from these methods do not intend to provide data for judgment on the absolute fire performance of any natural or treated natural tree, but rather provide a means for comparing the fire performance of treated versus untreated trees.

4.3 These test methods do not take into account the influence of decorations that are added to the tree.

4.4 For Test Method 1, only Fraser fir [4.5 For Test Method 2, Large Scale Fire Test, it is important that the treated and untreated tree specimens be evaluated consistently and as simultaneously as possible for adequate comparative results.

4.6 The performance of the treatment will vary depending on the uniformity of the application of the treatment. This quality of application is not determined by these test methods.

1.1 This 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.

1.2 The purpose of these test methods is to:

1.3 The 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.

1.4 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.

1.6 The 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.

1.7 This 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.
