Designation: D1037 - 12 Standard Test Methods for Evaluating Properties of Wood-Base Fiber and Particle Panel Materials 1 This standard is issued under the fixed designation D1037; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (´) indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense. INTRODUCTION The test methods presented herein have been developed and are presented to serve two distinct purposes. They are divided into two parts. Part A. General Test Methods for Evaluating the Basic Properties of Wood-Base Fiber and Particle Panel Materials—Part A is for use in obtaining basic properties suitable for comparison studies with other materials of construction. These refined test methods are applicable for this purpose to all materials covered by Definitions D1554. Part B. Acceptance and Specification Test Methods for Hardboard—Part B is for specific use in specifications for procurement and acceptance testing of hardboard. These test methods are generally employed for those purposes in the industry. By confining their intended use as indicated, it has been possible to achieve adequate precision of results combined with economy and speed in testing, which are desirable for specification use. The choice between a particular test method and its alternative should be made with a full understanding of the intended purpose of each, because values obtained from tests may, in some cases, differ. Of the test methods presented in both parts, some have been in generally accepted use for many years, some are modifications and refinements of previously developed test methods, and some are more recent developments. Where test methods are suitable for more than one of the purposes, they are delineated in Part A, but not repeated in Part B. It is the intent that reference to the appropriate section of the test method shall suffice in specifications developed for the different materials. 1. Scope 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 Significance and Use 3 Apparatus 4 Test Specimens 5 Moisture Content and Conditioning Requirements 6 Accelerated Aging 7 Size, Physical Properties and Appearance of Panels 8 Static Bending 9 Tension Parallel to Surface 10 Tension Perpendicular to Surface 11 Compression Parallel to Surface 12 Fastener Holding Tests: Lateral Nail Resistance 13 Nail Withdrawal 14 Nail-Head Pull-Through 15 Direct Screw Withdrawal 16 Hardness 17 Hardness Modulus 18 1 These test methods are under the jurisdiction of ASTM Committee D07 on Wood and are the direct responsibility of Subcommittee D07.03 on Panel Products. Current edition approved May 1, 2012. Published June 2012. Originally approved in 1949. Last previous edition approved in 2006 as D1037 – 06a. DOI: 10.1520/D1037-12.

United States 1 Section Shear in the Plane of the Panel 19 Glue-Line Shear (Block Type) 20 Falling Ball Impact 21 Abrasion Resistance by the U.S. Navy Wear Tester 22 Moisture Tests: Water Absorption and Thickness Swelling 23 Linear Expansion with Change in Moisture Content 24 Cupping and Twisting 25 Interlaminar Shear 26 Edgewise Shear 27 Compression-Shear 28 1.2 Part B—Acceptance and Specification Test Methods for Hardboard. The methods for Part B provide test procedures for measuring the following properties of hardboard: Section Thickness 32 Modulus of Rupture 33 Tension Strength Parallel to Surface 34 Tension Strength Perpendicular to Surface 35 Water Absorption and Thickness Swelling 36 Moisture Content and Specific Gravity 37 1.3 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 appro- priate safety and health practices and determine the applica- bility of regulatory limitations prior to use. 2.

Significance and Use 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 prop- erties of various materials, 3.3 Data for determining the influence on the basic proper- ties of such factors as raw material and processing variables, post-treatments of panels, and environmental influences, and 3.4 Data for manufacturing control, product research and development, and specification acceptance. 2 For referenced ASTM standards, visit the ASTM website, www.astm.org, or contact ASTM Customer Service at [email protected].
