Standard Test Methods for Determining the Effectiveness of Fire Retardant Treatments for Natural Christmas Trees

Importancia y uso:

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 [Abies fraseri (Pursh) Poi.] trees are tested. Although this is one of the most commonly used Christmas trees in the United States, it is possible that results for other tree species will differ from the results for this species.

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.
