This test method is useful in determining the relative efficacy between various treatments and naturally occurring wood-destroying agents. It is an initial means of estimating the tolerance limits of the biologically destructive agents or the threshold values of the chemical preservative, or both.This test method is not intended to provide quantifiable reproducible values. It is a qualitative method designed to provide a reproducible means of establishing relative efficacy between experimental contract levels.1.1 This test method covers the relative effectiveness of wood preservatives in small wood specimens exposed to a natural marine environment. It is not within the scope of this test method to determine the retention or duration of protection for commercial size piles and timbers.1.2 The requirements for preparing the material for testing and the test procedures appear in the following order: SectionSummary of Test Method Test Specimens Pretreatment Handling Treatment Procedure Post-Treatment Handling Assembly of Test Specimens Exposure Inspection Evaluation of Results Reports 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 and health practices and determine the applicability of regulatory limitations prior to use.

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.

This test method covers accelerated procedures for determining the relative permanence and effectiveness of wood preservatives in stakes exposed in field plots. The sapwood of southern pine shall be the preferred wood for comparative tests. The pretreatment selections and treatment procedure of test stakes are presented in details. The after treatment handling of test stakes, and installation of stakes are presented in details. The periodic calculation of the index of condition, short-cut method, percent of index condition, and termination of test shall be evaluated to meet the requirements prescribed.1.1 This test method covers accelerated procedures for determining the relative permanence and effectiveness of wood preservatives in stakes exposed in field plots.1.2 The requirements for preparation of the material for testing and the test procedures appear in the following order:1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.

1.1 These test methods cover sampling of creosote, creosote-coal tar solutions, creosote-petroleum solutions, and oilborne and waterborne preservatives. Note 1-See Specification D390, for Coal-Tar Creosote for the Preservative Treatment of Piles, Poles, and Timbers for Marine, Land, and Fresh Water Use, Specification D391 for Creosote-Coal Tar Solution, and Specification D1858, for Creosote-Petroleum Solution. 1.1.1 Creosote and creosote solutions are homogeneous liquids, except for their moisture content. At atmospheric temperatures, however, part of the creosote is usually in crystalline form, and shall be heated to a temperature at which it is entirely liquid before sampling. 1.1.1.1 When sampling creosote and creosote solutions, the object is to obtain a sample that will be representative of the water content, and the methods of sampling described are intended to accomplish that purpose. 1.1.2 Recommended test methods are given for sampling a preservative in a liquid or solid state and in the several types of containers in which they are likely to be encountered. Creosote, creosote-coal tar, and creosote-petroleum solutions may be in the form of a liquid or semiliquid. Oilborne and waterborne preservatives may be in the solid state, in concentrated solutions, or in ready-to-use solutions. 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.

This test method is useful in the development of new wood preservatives and preservative systems by evaluating the minimum preservative retention to prevent decay under laboratory conditions. The results are used to facilitate target retentions in subsequent tests for effectiveness against termites (see Test Method D 3345) and in field stakes (see Test Method D 1758). The sections on Treatment and Preservative Permanence are referenced by other ASTM standards. The test method assumes that the test blocks exposed to certain conditions after treatment will achieve equilibrium, and will return to the same equilibrium after exposure to fungi. This assumption may lead to weight loss that is not due to decay. The test uses live cultures of fungal organisms that require careful colonization, storage, and feeding to remain viable strains.1.1 This test method covers determination of the minimum amount of preservative that prevents decay of selected species of wood by selected fungi under optimum laboratory conditions. 1.2 The requirements for preparation of the material for testing and the test procedure appear in the following order: Section TitleSection Summary of Test Method3 4 Apparatus5 Reagents6 Wood and Test Blocks7 Test Fungi8 Culture Media9 Preparation of Test Cultures10 Preparation and Impregnation of Test Blocks11 Conditioning Treated Blocks12 Preservative Permanence13 Stabilization of Treated Test Blocks and Placement in Culture Bottles14 Incubation and Duration of Test15 Handling Test Blocks After Exposure to Test Fungi16 Calculation of Weight Losses17 Evaluation of Test Results18 Refining the Threshold19 Report20 Precision and Bias21 Keywords22 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 and health practices and determine the applicability of regulatory limitations prior to use.
