5.1 This test method is considered satisfactory for acceptance testing of commercial shipments because the method has been used extensively in the trade for acceptance testing.5.1.1 If there are differences of practical significance between reported test results for two laboratories (or more), comparative tests should be performed to determine if their is a statistical bias between them, using competent statistical assistance. As a minimum, the test samples should be used that are as homogeneous as possible, that are drawn from the material from which the disparate test results were obtained, and that are randomly assigned in equal numbers to each laboratory for testing. Other materials with established test values may be used for this purpose. The test results from the two laboratories should be compared using a statistical test for unpaired data, at a probability level chosen prior to the testing series. If a bias is found, either its cause must be found and corrected, or future test results must be adjusted in consideration of the known bias.1.1 This test method covers the determination of the degree of color that may be transferred from the textile tape of zippers of all fibers to other surfaces by rubbing under wet or dry conditions, or both.1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 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.

Preservatives of the metallic series and oil soluble preservatives are not readily apparent in a cross section of wood either due to similar color to the species of wood or lack of color of the preservative itself. Chemical staining of a treated specimen of wood reveals the presence of the preservative. The sapwood and heartwood of Douglas-Fir and the pine species can be differentiated by a chemical stain.1.1 These test methods cover procedures for determining penetration of preservatives in wood in cases where demarcation between the treated and untreated wood is not readily visible. Included are test methods for differentiating the heartwood and the sapwood of wood samples for specific species, and a test method for differentiating the heartwoods between the red oaks and the white oaks. 1.2 The procedures appear in the following order: Procedure Sections Penetration of Arsenic-Containing Preservatives 6 to 8 Penetration of Copper-Containing Preservatives 9 to 11 Penetration of Fluoride-Containing Preservatives 12 to 15 Penetration of Pentachlorophenol Using 4,4[prime]-bis-Dimethylamino-Triphenylmethane (DMTM) 16 to 20 Penetration of Pentachlorophenol Using a Silver-Copper Complex Known as "Penta-Check" 21 to 24 Penetration of Solvent Used With Oil-Soluble Preservatives 25 to 28 Penetration of Zinc-Containing Preservatives 29 to 32 Differentiating between Sapwood and Heartwood in Pine Species (Pinus sp.) 33 to 36 Differentiating between Sapwood and Heartwood in Douglas Fir (Pseudotsuga menziesii) 37 to 40 Differentiating between Sapwood and Heartwood in White Fir (Abies concolor) 41 to 44 Differentiating Between Woods of the Red Oak and the White Oak Species 45 to 48 1.3 This standard does not purport to address all of the safety problems, 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.

5.1 The tests results represent afterflame and afterglow time in seconds for a material of specified shape, under the conditions of this test method.5.2 The effect of material thickness, color additives, and possible loss of volatile components is measurable.5.3 The results, when tabulated, are potentially useful as a reference for comparing the relative performance of materials and as an aid in material selection.5.4 In this procedure, the specimens are subjected to one or more specific sets of laboratory test conditions. Different test conditions will likely result in changes in the fire-test-response characteristics measured. Therefore, the results are valid only for the fire-test-exposure conditions described in this test method.1.1 This fire-test-response standard covers a small-scale laboratory procedure for determining comparative burning characteristics of solid-plastic material, using a 20-mm (50W) premixed flame applied to the base of specimens held in a vertical position.NOTE 1: This test method and the 20 mm (50W) Vertical Burning Test (V-0, V-1, or V-2) of ANSI/UL 94 are equivalent.NOTE 2: This test method and Test Method B of IEC 60695–11–10 are equivalent. IEC 60695–11–10 has replaced ISO 1210.NOTE 3: For additional information on materials that burn up to the holding clamp by this test method, see Test Method D635. For test methods of flexible plastics in the form of thin sheets and film, see Test Method D4804. For additional information on comparative burning characteristics and resistance to burn-through, see Test Method D5048.1.2 This test method was developed for polymeric materials used for parts in devices and appliances. The results are intended to serve as a preliminary indication of their acceptability with respect to flammability for a particular application. The final acceptance of the material is dependent upon its use in complete equipment that conforms with the standards applicable to such equipment.1.3 The classification system described in the appendix is intended for quality assurance and the preselection of component materials for products.1.4 It is possible that this test is applicable to nonmetallic materials other than plastics. Such application is outside the scope of this technical committee.1.5 This test method does not cover plastics when used for building construction, finishing or contents such as wall and floor coverings, furnishings, decorative objects etc. In addition, the fire resistance (in terms of an hourly rating), flame spread, smoke characterization and heat release rate are not evaluated by this test. Other fire tests exist and shall be used to evaluate the flammability of materials in these intended end use product configuration.1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.7 This standard is used to measure and describe the response of materials, products, or assemblies 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 materials, products, or assemblies under actual fire conditions.1.8 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.9 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.
