INTRODUCTION
The speciﬁc gravity is the weight of any given volume of a substance divided by the weight of an
equal volume of water. As both the weight and volume of wood vary with the amount of moisture
contained in the wood, speciﬁc gravity as applied to wood is an indeﬁnite quantity unless the
conditions under which it is determined are clearly speciﬁed.The speciﬁc gravity of wood is generally
basedontheweightwhenoven-dry,butthevolumemaybethatintheoven-dry,partiallydry,orgreen
condition. The amount of moisture retained at any equilibrium condition is proportional to the dry
weight of the specimen, and for this reason moisture content is normally expressed as a percent of the
oven-dry weight of the wood.

Standard Test Methods for Conducting Machining Tests of Wood and Wood-Base Panel Materials

SIGNIFICANCE AND USE
4.1 Machining tests are made to determine the working qualities and characteristics of different species of wood and of different wood-based panel materials under a variety of machine operations such as are encountered in commercial manufacturing practice. The tests provide a systematic basis for comparing the behavior of different products with respect to woodworking machine operations and of evaluating their potential suitability for certain uses where these properties are of prime importance.
SCOPE
1.1 These test methods cover procedures for planing, routing/shaping, turning, mortising, boring, and sanding, all of which are common wood-working operations used in the manufacture of wood products. These tests apply, in different degrees, to two general classes of materials:
1.1.1 Wood in the form of lumber, and
1.1.2 Wood-base panel materials such as plywood and wood-base fiber and particle panels.
1.2 Because of the importance of planing, some of the variables that affect the results of this operation are explored with a view to determining optimum conditions. In most of the other tests, however, it is necessary to limit the work to one set of fairly typical commercial conditions in which all the different woods are treated alike.
1.3 Several factors enter into any complete appraisal of the machining properties of a given wood or wood-base panel. Quality of finished surface is recommended as the basis for evaluation of machining properties. Rate of dulling of cutting tools and power consumed in cutting are also important considerations but are beyond the scope of these test methods.
1.4 Although the methods presented include the results of progressive developments in the evaluation of machining properties, further improvements are anticipated. For example, by present procedures, quality of the finished surface is evaluated by visual inspection, but as new mechanical or physical techniques become available that will afford improved precision of evaluation, they should be employed.
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.6 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.
1.7 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.

Standard Test Methods for Density and Specific Gravity (Relative Density) of Wood and Wood-Based Materials

SIGNIFICANCE AND USE
5.1 Density and specific gravity are cornerstone terms that help define many useful properties of wood and wood-based materials. These terms designate concepts that have distinct definitions though they relate to the same characteristic (mass in a unit volume). Generally, in the US and Canada, density of wood is measured in terms of specific gravity, or relative density. In the wood-based composites industry and internationally the term density is often preferred.
5.2 The basic density and basic specific gravity of wood are used in the forestry industry for calculating the oven-dry weight of wood fiber contained in a known wood volume of various wood species. Thus, it serves as an indicator of the amount of wood pulp that could be produced, the workability of the material or its shipping weight. This information is referenced in various resources, including Wood Handbook.5 Note that specific gravity varies within a tree, between trees, and between species. Since the specific gravity of wood cell wall substance is practically constant for all species (approximately 1.53), it is apparent that individual specific gravity value is indicative of the amount of wood cell wall substance present. It affords a rapid and valuable test method for selection of wood for specific uses. In US and Canadian building codes, the oven-dry specific gravity is correlated to various strength characteristics of wood products (for example, compression perpendicular to grain, shear strength and fastener holding capacity).
5.3 It is often desirable to know the density or specific gravity of a living tree, a structural member already in place, a log cross section, a segment of a research element, or the earlywood or latewood layer. Therefore, it is possible that specimens will be large or small, regular or irregular in shape, and at a variety of moisture contents. These test methods give procedures that include all of these variables and provides for calculation of density and specific gr...

Standard Test Method for Hygroscopic Properties of Fire-Retardant Wood and Wood-Based Products

SIGNIFICANCE AND USE
4.1 The hygroscopic properties of wood and wood-based products treated with fire-retardant chemicals are often greater than for untreated products. This is particularly true at the higher relative humidity conditions. This higher hygroscopicity sometimes is the cause for staining, decay, poor paint adhesion, and migration and exuding of chemicals and moisture at the high humidities. Corrosion of metal fasteners sometimes also occurs.
4.2 The results obtained with this standard are important in identifying treatments with low hygroscopic properties.
4.3 Results can be useful in determining exposure limitations in service for specific treated products.
4.4 Building codes and other specifications for fire-retardant-treated wood for interior use include requirements based on this test method.
SCOPE
1.1 This test method prescribes the procedure for determining the hygroscopicity of fire retardant treated wood products by determining the moisture content of fire-retardant-treated wood and wood-based product specimens after exposure to a test condition of 92 ± 2 % relative humidity at 81 ± 4°F [27 ± 2°C].
1.2 The text of this test method references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this test method.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems has the potential to result in non-conformance with the standard.
1.4 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.
1.5 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.

Standard Test Methods for Direct Moisture Content Measurement of Wood and Wood-Based Materials

SIGNIFICANCE AND USE
4.1 Moisture content is one of the most important variables affecting the properties of wood and wood-based materials. The procedures in these test methods are structured to permit the full range of use from fundamental research to industrial processing. Method A is the reference (primary) standard for determining moisture content of wood and wood-based materials, which is designed for obtaining the most precise values of moisture content consistent with the needs of the user. It provides means of assessing variability contributed by the oven or specimen hygroscopicity, or both. In addition, criteria are described for defining the endpoint in oven-drying. Method B provides relatively simple procedures of measuring moisture content, but generally with a lower precision than Method A. Representativeness of the specimens to the full-size product, including knots, sapwood, and heartwood, needs to be considered. These methods are not recommended for use with treated wood products impregnated with creosote, petroleum, and their solutions where the volatile non-wood chemicals contained in the specimen introduce greater bias than desired in the results.
SCOPE
1.1 These test methods cover the determination of the moisture content (MC) of wood, veneer, and other wood-based materials, including those that contain adhesives and chemical additives. The test procedures appear in the following order:
Sections
Method A—Primary Oven-Drying Method
5
Method B—Secondary Oven-Drying Method
6
1.2 The primary oven-drying method (Method A) is intended as the sole primary method. It is structured for purposes where the highest accuracy or degree of precision is needed (for example, research or calibration).
1.3 The secondary oven-drying method (Method B) is intended for the purposes where the primary procedure (Method A) is not desired or justified. Test results in this method are generally less precise than in Method A.
1.4 For materials that have been chemically treated or impregnated with creosote, petroleum, and their solutions such that the oven-drying procedures introduce greater bias than desired in the results, other methods, such as AWPA A6, are recommended.
1.5 Units—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.
1.6 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.
1.7 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.

Standard Test Methods for Mechanical Properties of Lumber and Wood-Based Structural Materials

SIGNIFICANCE AND USE
4.1 These test methods provide procedures that are applicable under true field conditions, such as in a plant with specimens not at moisture equilibrium.
4.2 The data established by these test methods can be used as follows:
4.2.1 Develop strength and stiffness properties for the population represented by the material being tested (that is, individual grades, grade combinations, species, species groups, or any other defined, identifiable sample).
4.2.2 Confirm the validity of strength and stiffness properties for the population represented by the material being tested.
4.2.3 Investigate the effect of parameters that have the potential to influence the strength and stiffness properties of the material, such as moisture content, temperature, knot size and location, or slope of grain.
4.3 The procedures chosen in accordance with these test methods shall be fully documented in the report to facilitate correlation with test results obtained through the use of traditional procedures, such as those set forth in Test Methods D198.
SCOPE
1.1 These test methods cover the determination of the mechanical properties of stress-graded lumber and other wood-based structural materials.

Standard Test Method for Performance of Wood and Wood-Based Floor and Roof Sheathing Under Concentrated Static and Impact Loads

SIGNIFICANCE AND USE
5.1 The procedures outlined will provide data that can be used to evaluate the structural performance, under concentrated loads, of roof and floor sheathing, separate from the effects of the framing, under simulated conditions representative of those in actual service.
5.2 The procedures are intended to be applied to roof or floor sheathing materials installed directly to framing. They are not intended for the evaluation of the framed assembly as a whole.
SCOPE
1.1 This test method covers procedures for determining the resistance to deflection and damage of floor and roof sheathing used in site-built construction subjected to concentrated static loads as well as impact loads from nonrigid blunt objects. It is applicable to wood and wood-based panels and boards, but is not intended to cover profiled metal decks, nor precast or cast-in-place slabs. Surface indentation is not evaluated separately from deflection.
1.2 Three applications are covered: roof sheathing, subfloors, and single floors. Roof sheathing is tested in both a dry and a wet condition, while subfloors and single floors are both tested in a dry condition, as well as a condition of having dried out after being wet. These moisture conditions are those commonly experienced with site-built construction.
Note 1: Where it is anticipated that sheathing will be subjected only to dry conditions during construction and use, or else to greater moisture exposure than is indicated in 7.3.2, the corresponding exposure conditions may be modified by agreement between the interested parties. For example, shop-built construction may be tested dry only, although the possibility of exposure to high humidity or leaks and flooding during use should be considered.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4 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.
1.5 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.
