Standard Test Methods for Evaluating Properties of Wood-Base Fiber and Particle Panel Materials

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.
