1.1 This practice includes the physical condition and compositional criteria for selecting post-consumer gypsum panel products for use in manufacturing new panel products. 1.2 This practice applies to gypsum panel products as defined in standards Specifications C1177/C1177M, C1178/C1178M, C1278/C1278M, C1396/C1396M, and C1658/C1658M. 1.3 This practice does not dictate the minimum amount of recycled content a manufacturer is required to use in producing new panel products. 1.4 This practice does not address recycling of gypsum panel products from demolition projects nor from any source other than newly installed gypsum panel products. 1.5 Units--The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.6 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.
This practice will allow the industry to develop quality products that will meet their criteria while integrating recycled material, a demand of the marketplace.
