AMCA 550:2015

Changes included in this revision to BSR/AMCA 550:1. In order to be able to test a louver to the AMCA 550 standard and then check test it under AMCA 500-L Wind Driven Rain, the louver size was changed from a 48'x48' to a 1000mm x 1000mm (39.37 in. x 39.37 in.) core area louver which is the standard size for the AMCA 500-L test. 2. The AMCA 550 test standard was developed to replicate the Dade County Test Standard, TAS-100a. Most louvers that were originally tested for this Dade County Test Standard required a damper behind the louver in the closed position. Changes have been made to this standard in order to address and call out when these dampers are use
