ASTM D5664-10

Standard Test Method for Evaluating the Effects of Fire-Retardant Treatments and Elevated Temperatures on Strength Properties of Fire-Retardant Treated Lumber

SIGNIFICANCE AND USE
The mechanical properties evaluated by this test method provide the following:
Data for use in developing modification factors for the allowable design properties of fire-retardant treated lumber when used at or near room temperatures (see 6.3).
Data for use in developing modification factors for allowable design properties of fire-retardant treated lumber when exposed to elevated temperatures and humidity (see 6.4).
Data (optional) for use in modifying these factors for size effects when fire-retardant treated lumber is used at or near room temperature and when exposed to elevated temperatures and humidity (see 6.5).
Data from the first two procedures in this test method of evaluation are indicative only for that species.
Note 1—The results of the three listed species (Southern pine, Douglas fir, and either white spruce or a Spruce/Fir mixture) may be used together to make inference on untested wood species because the three tested species represent the full spectrum of expected treatability.
Data from the optional third part of this three-part method of evaluation are indicative for all species because it is primarily used to assess size effects.
SCOPE
1.1 This test method covers procedures for obtaining data to assess the initial adjustments to allowable design stresses for lumber treated with candidate commercial fire-retardant (FR) formulations and further procedures for obtaining data to assess the effect of extended exposure to elevated temperature of 66 ± 2°C (150 ± 4°F).
1.2 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.

4.1 The general objectives of this test method are to develop data to adjust allowable design stresses of FR-treated lumber for
the initial effects for the tested FR-formulation(s) and to develop data on in-service thermal stability after extended exposure to
environmental conditions up to 66 6 2°C (150 6 4°F) and$50 % relative humidity.
