【国外标准】 Standard Test Methods for Evaluating Properties of Wood-Base Fiber and Particle Panel Materials

3.1 These test methods cover small-specimen tests for wood-base fiber and particle panel materials that are made to provide:3.2 Data for comparing the mechanical and physical properties of various materials,3.3 Data for determining the influence on the basic properties of such factors as raw material and processing variables, post-treatments of panels, and environmental influences, and3.4 Data for manufacturing control, product research and development, and specification acceptance.3.5 Not all the tests outlined in these test methods may be necessary to evaluate any particular panel for any specified use. In each instance, therefore, it will be necessary to determine which tests shall be made.1.1 Part A—General Test Methods for Evaluating the Basic Properties of Wood-Base Fiber and Particle Panel Materials—These test methods cover the determination of the properties of wood-base fiber and particle panel materials that are produced as mat-formed panels such as particleboard, medium-density fiberboard, hardboard, and oriented strand board.  Section 3Apparatus 4Test Specimens 5Moisture Content and Conditioning Requirements 6Accelerated Aging 7Size, Physical Properties and Appearance of Panels 8Static Bending 9Tension Parallel to Surface 10Tension Perpendicular to Surface 11Compression Parallel to Surface 12Fastener Holding Tests:   Lateral Nail Resistance 13 Nail Withdrawal 14 Nail-Head Pull-Through 15 Direct Screw Withdrawal 16Hardness 17Hardness Modulus 18Shear in the Plane of the Panel 19Glue-Line Shear (Block Type) 20Falling Ball Impact 21Abrasion Resistance by the U.S. Navy Wear Tester 22Moisture Tests:   Water Absorption and Thickness Swelling 23 Linear Expansion with Change in Moisture Content 24Cupping and Twisting 25Interlaminar Shear 26Edgewise Shear 27Compression-Shear 281.2 Part B—Acceptance and Specification Test Methods for Hardboard—The methods for Part B provide test procedures for measuring the following properties of hardboard:  SectionThickness 32Modulus of Rupture 33Tension Strength Parallel to Surface 34Tension Strength Perpendicular to Surface 35Water Absorption and Thickness Swelling 36Moisture Content and Specific Gravity 371.3 There are accepted basic test procedures for various fundamental properties of materials that may be used without modification for evaluating certain properties of wood-based fiber and particle panel materials. These test methods are included elsewhere in the Annual Book of ASTM Standards. The pertinent ones are listed in Table 1. A few of the test methods referenced are for construction where the wood-base materials often are used.1.4 The values stated in inch-pound units are to be regarded as the standard. The SI equivalents are approximate in many cases. 1 in. = 25.4 mm, 1 lbf = 4.45 N.1.5 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.1.6 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.
