3 These products have been determined to be incompatible based on compositional information found in the manufacturer’s labeling or published literature.

Products qualify for the program by undergoing testing that demonstrates the product is compatible with FlowGuard Gold Pipe & Fittings, BlazeMaster Fire Sprinkler Systems and Corzan Industrial Systems. 
Manufacturers of the program's products are committed to maintaining necessary product quality and agree not to change the chemical composition of the product without advance written notice. If there is a change in the chemical composition, manufacturers must re-submit their products in order to be included in the FBC System Compatible Program. Manufacturers must also submit their products to periodic testing to ensure the products remain chemically compatible. Because CPVC products are made with base resins having different molecular weights and varying chlorine contents and compound additives, the FBC System Compatible Program can verify chemical compatibility of products made with Lubrizol's FlowGuard, BlazeMaster and Corzan compounds with the ancillary products tested and added to the Lubrizol FBC™ System Compatible Program.
Products in the program display the FBC System Compatible mark on their labels. This mark quickly notifies installers that the product is chemically compatible with FlowGuard, BlazeMaster and Corzan CPVC products. The FBC System Compatible Program is in active use in the United States, Canada, Mexico, 25 European countries, the United Arab Emirates, India and China.
