Standard Test Methods for
Wood-Based Structural Panels in Compression1

This standard is issued under the fixed designation D 3501; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

This standard has been approved for use by agencies of the Department of Defense.

1. Scope

1.1 These test methods cover the determination of the
compression properties of wood-based structural panels.
Wood-based structural panels in use include plywood, wafer board, oriented strand board, and composites of veneer and of
wood-based layers.

1.2 Method A, Compression Test for Small Specimens—This
the method is applicable to small specimens that are uniform with
respect to elastic and strength properties. Two types of compression tests are employed: one to evaluate both elastic and
compressive strength properties, and the second to evaluate
maximum compressive strength only.

1.3 Method B, Compression Test for Large Specimens—
This method employs large specimens and responds well to
manufacturing variables and growth characteristics that influence compression properties of structural panels.

1.3.1 This method is intended for the following:

1.3.1.1 Comparative tests of structural panels,

1.3.1.2 Evaluating the effects of moisture content on
strength properties of structural panels,

1.3.1.3 Determining the strength properties of structural
panels, and

1.3.1.4 Evaluating the effects of raw material and manufacturing variables on compression properties of structural panels.

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 and health practices and determine the applicability of regulatory limitations prior to use.
