Which term describes evaluating materials for safe interaction?

• A. Gauge Pressure
• B. Nonmetallic Pipe
• C. Compatibility Testing
• D. ASME B16.4

Answer: (C)

Compatibility testing is the process of evaluating materials to ensure they interact safely within a sprinkler system. In low-rise residential systems, this means checking that pipes, fittings, gaskets, elastomers, sealants, and any additives or antifreeze won’t react with the water, with each other, or with system chemicals. The goal is to prevent issues like corrosion, swelling or degradation of seals, or deposits that could affect sprinkler performance or water quality over time. Gauge pressure is simply measuring pressure, not how materials interact. Nonmetallic pipe refers to a material option, not the evaluation process. ASME B16.4 is a standard for flanged fittings, not a method for testing material compatibility.
