Certified Ratings Program - Acoustical Duct Silencers
Products that can be licensed by AMCA International to bear the AMCA International Certified Ratings Seal are prefabricated acoustical duct silencers. Prefabricated acoustical duct silencers are defined as silencers that are constructed in advance, or manufactured in standard assemblies or sections ready for field installation. The program applies to acoustical duct silencers within the scope of AMCA International for which performance rating catalogs are published and made available to the public. When performance ratings for both licensed and unlicensed products are contained in the same catalog, there must be a clear distinction made between licensed and unlicensed products, as required in Section 11 of AMCA International Publication 11, Certified Ratings Program Operating Manual.
