ASTM D5651-21

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: D5651 − 13 D5651 − 21
Standard Test Method for
Surface Bond Strength of Wood-Base Fiber and Particle
Panel Materials
This standard is issued under the fixed designation D5651; 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.
1. Scope
1.1 This test method is a measure of the cohesive bond strength of the fibers, or particles, on the surface of wood-base fiber and
particle panels (for example, particleboard and medium-density fiberboard) in the direction perpendicular to the plane of the panel.
1.1.1 To determine the internal cohesive bond strength of wood-base fiber and particle panels, use Section 11 of Test Methods
D1037.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 This test method 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 safety, health, and healthenvironmental 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.

Process
3. Significance and Use
3.1 This test method provides a measure of the bond quality of the fibers, or particles, at the surface of wood-base fiber and particle
panel materials including particleboard, medium-density fiberboard (MDF) and oriented strand board (OSB). Surface bond
strength is a measure of the strength and resistance to delamination of the bond between overlay materials and panel surfaces and
is an important consideration when these overlay materials, such as wood veneers, saturated papers, or plastic overlays, are to be
bonded to the panel surface during secondary manufacturing.
This test method is under the jurisdiction of ASTM Committee D07 on Wood and is the direct responsibility of Subcommittee D07.03 on Panel Products.

4. Apparatus
4.1 The apparatus required for this test method is shown in Fig. 1.
4.1.1 The test cylinder shall be 28.7 mm (1.13 in.) 28.7 mm (1.13 in.) in diameter, providing a test surface area of 645.2
mm645.2 mm (1 in.(1 in. ), and the cylinder length shall be approximately 25 mm (1 in.). 25 mm (1 in.). One face of this cylinder
shall be smoothly finished for gluing, while a threaded hole shall be placed in the center of the opposite face and also aligned
perpendicular to the gluing face.
4.1.2 The lower test fixture shall consist of a 6-mm (0.25- in.) steel plate mounted in a plane perpendicular to the direction of test.
The mounting shall be such that this plate is held rigidly and there is at least 60-mm (2.36-in.) clearance beneath it to permit entry
of the test assembly. This plate shall have a hole drilled in the center that is 2 mm (0.08 in.) 2 mm (0.08 in.) larger than the diameter
of the test cylinder.
4.1.3 The upper arm of the test machine shall have a threaded means of engaging the threaded hole in the top of the test cylinder
so as to apply a force that shall move the test cylinder in a direction perpendicular to the lower test fixture and surface of the test
specimen. A self-aligning joint (universal joint) is required in the upper arm of the test fixture.
4.1.3.1 Alternate connecting devices such as a swivel and hook or ball and socket, are allowed for fixing the test cylinder to the
upper arm of the test machine. If alternate connecting devices are used, this shall be noted on the test report.
5. Sampling and Test Specimens
5.1 A minimum of three tests from each panel surface to be considered shall be made to determine the surface bond strength of
a single panel. Panels for testing shall be selected in a manner consistent with the sampling procedures specified in Practice E122.
5.2 The test specimen shall be a minimum of 75 mm (3 in.) 75 mm (3 in.) square. The minimum specimen thickness required for
this test is 13 mm (0.5 in.). 13 mm (0.5 in.). If necessary, laminate two
