The FBC™ System Compatible Program
Eliminate the Guesswork
Associated with Chemical Compatibility
To ease the burden associated with researching and selecting accompanying
construction products, Lubrizol developed the FBC™ System Compatible Program.
This resource is made available to manufacturers of ancillary products to
assist in determining their product’s chemical compatibility with Lubrizol’s
FlowGuard®, BlazeMaster®, and Corzan® CPVC piping systems.
for inclusion in the FBC System Compatible Program, the manufacturer of
auxiliary construction products must agree to:
- Submit their
products for testing by a third-party lab.
- Not alter the tested
- Have their manufacturing facility audited annually by the
The FBC System Compatible Program serves the
industry with active use in the U.S., Canada, Mexico, 25 European countries,
the United Arab Emirates, India and China. (Footnote: Users should be aware
that other standards exist or are being developed to serve the industry, such
as FM 1635, Approval Standard for Plastic Pipe and Fittings for Automatic
While consulting directly with the manufacturer of
the ancillary products is always a good practice, the FBC System Compatible
Program assists in the effort to eliminate guesswork associated with
identifying chemical compatibility. Products accepted into the program are
given the right to display this FBC System Compatible mark on their labels.
Once this mark has been applied, it demonstrates the ancillary product
manufacturer’s commitment not to make changes to the formulation of the
product without advance written notice and retesting.
important to note, however, that not all CPVC products are identical.
Different CPVC products may vary in molecular weight, chlorine content and
compound additives. As a consequence of these variables, the FBC System
Compatible Program can only help determine chemical compatibility with the
aforementioned Lubrizol brands.
The FBC™ System Compatible Program is a resource
made available to manufacturers of ancillary products intended to be used with
CPVC to help determine whether a product is chemically compatible with
Lubrizol’s FlowGuard®, BlazeMaster®, and Corzan® CPVC piping systems. Other
manufacturers and/or brands of CPVC piping have not been tested as part of the
FBC™ System Compatible Program. The FBC™ System Compatible program is,
therefore, only applicable to the chemical compatibility of ancillary products
with the Lubrizol brands of FlowGuard, BlazeMaster, and Corzan CPVC piping
systems. This distinction is made because every brand of CPVC piping is made
with unique compounds, some of which may contain resins with different
molecular weights and varying chlorine content. These characteristics directly
impact the performance of the resulting product. Similarly, various CPVC
products contain different performance additives. This too affects the
performance characteristics of the ancillary product. For these reasons,
Lubrizol has no responsibility for any failures occurring as a result of using
products in the FBC System Compatible Program with CPVC products other than
FlowGuard, BlazeMaster, and Corzan.
