AMCA International reaffirmed AMCA publication 1011-03, a Certified Ratings Program Product Rating Manual for Acoustical Duct Silencers, and provides a program for certifying a product's sound dynamic insertion loss, airflow generated noise, and pressure drop performance ratings.
Products that can be licensed by AMCA to bear the AMCA 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, a clear distinction must be made between licensed and unlicensed products, as required in Section 11 of AMCA International Publication 11, Certified Ratings Program Operating Manual.
When licensed products are used as component parts of a larger unit, the AMCA International Certified Ratings Seal shall not be applied to the complete unit. The seal can only be applied to the individually licensed components.
