Причина отмены These test methods provided a measure of the moisture resistance of cellulosic-based fiber and particle panels (for example, medium-density fiberboard (MDF), particleboard, and hardboard).

Formerly under the jurisdiction of Committee D07 on Wood, this test method was withdrawn in January 2020 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

Значение и использование

These test methods provide a measure of the moisture resistance of cellulosic-based fiber and particle panels (for example, medium-density fiberboard (MDF), particleboard, and hardboard). This test methodology can be used to assess the thickness swelling and bond integrity characteristics of panels engineered for interior end-use applications involving exposure to cyclic temperatures and intermittent wetting environments.

Область применения

1.1 These test methods provide a measure of the moisture resistance of cellulosic-based fiber and particle panels (for example, medium-density fiberboard (MDF), particleboard, and hardboard). Resistance to moisture changes is measured by dimensional and internal bond changes and does not refer to decay/mold resistance or other performance aspects.

1.2 These test methods do not address structural properties or performance following moisture exposure. Panels are subjected to repeated cycles of water submersion and oven drying. After three cycles, the test specimens are tested for thickness swelling (TS) and internal bond (IB) strength.    

1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

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.
