An updated standard

Abstract
If you specify, supply or install mop-applied asphalt roofing materials, NRCA encourages you to use asphalt that complies with ASTM D312-15. Furthermore, NRCA now recommends consideration be given to specifying and using asphalt suppliers’ proprietary “low-fuming” asphalt formulations. Asphalts’ low-fuming additives are not currently addressed (or excluded) within ASTM D312-15 and, therefore, need to be specifically requested in addition to specifying ASTM D312-15.
