ASTM C240-08

Standard Test Methods of Testing Cellular Glass Insulation Block

SIGNIFICANCE AND USE
From a general standpoint, these test methods outline the particular points which have to be taken into account when applying ASTM standard test methods to the case of cellular glass insulating block.
SCOPE
1.1 These test methods cover the testing of cellular glass insulation block for density, water absorption, compressive strength, flexural strength at ambient temperature; preparation for chemical analysis; and thermal conductivity measurements.
1.2 The values stated in SI are generally to be regarded as the standard. The SI dimensions are to be used for material supplied in metric sizes. The inch dimensions are to be used for material supplied in inch sizes.
1.3 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.
