4.1 This test method is used for measuring the relative abilities of metal preservatives to prevent the rusting of steel panels under conditions of high humidity. It should not be relied upon to predict the effectiveness of a metal preservative in which high humidity is not the principal factor in the rusting.4.2 Comparisons made by this test method should normally be limited to similar metal preservative combinations designed for similar applications. The test life required for each type of metal preservative and for each intended application should be based on actual experience with that type of preservative in the intended service.4.3 Since the precision of the test method appears to be less than desired, a number of repeat tests may be necessary to establish the test life of a given metal preservative, and repeat tests by this test method in more than one cabinet are sometimes desirable.4.4 The data obtained from this accelerated test is of interest only in eliminating the most unsuitable materials or for indicating a probable relative order of protection against rust under conditions of high humidity. This test method does not prescribe the exposure periods to be used for a specific product, nor the interpretation to be given to the results.1.1 This test method covers the evaluation of the rust-preventive properties of metal preservatives under conditions of high humidity.1.2 The values stated in SI units are to be regarded as the standard except where the test apparatus or consumable parts are only available in other units. In such cases these will be regarded as standard. The values given in parentheses are for information only.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 consult and 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.
