Plenum Ratings for Cable Ties
In the United States & Canada, cable ties installed in areas used for the exchange of environmental air (air-handling spaces or “plenums”) are required to be classified as AH-1 or AH-2. UL 62275 includes a Smoke and Heat Release Test which results in a specific minimum index of characteristics. This index is in line with the national mechanical installation codes.
