Solder Alloys Solidus Temperature Table 5.2.1 Chlorinated polyvinyl chloride pipe for fire protection

Correct Answer:

Chlorinated polyvinyl chloride pipe for fire protection

Explanation:

CPVC stands for chlorinated polyvinyl chloride, which is a plastic piping material specifically manufactured for fire-protection use. In NFPA 13R, CPVC pipe is recognized as an acceptable material for sprinkler systems where listed and approved, offering a plastic alternative to metal piping in suitable residential applications. The other options aren’t material types used for pipe: solder alloys are used to join metal pipes, solidus temperature is a metallurgical term, and a table reference isn’t describing a material.
