1.1 Specification D3924 defines a standard environment of 23 ± 2°C and 50 ± 5 % relative humidity and free from drafts for normal conditioning and testing of paint, varnish, lacquer, and related materials. This practice describes a test chamber that allows for control of relative humidity above the ambient relative humidity and minimization of air flow for conditioning of test panels at elevated relative humidity and room temperatures.
1.2 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.
1.3 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.
