Historical Standard: ASTM C272-91(1996) Standard Test Method for Water Absorption of Core Materials for Structural Sandwich Constructions
SUPERSEDED (see Active link, below)
1.1 This test method covers the determination of the relative amount of water absorption by various types of structural core materials when immersed or in a high relative humidity environment. This test method is intended to apply to only structural core materials; honeycomb, foam, and balsa wood.
1.2 The values stated in SI units are to be regarded as the standard. The inch-pound units given may be approximate.
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.
