SynC · Topic
These are the standards in the SynC Standards library that cover Dry Pipe Sprinklers. Each one is a complete, plain-language specification: the scope it applies to, the requirements that govern it, and a structured equipment datasheet listing the values a project has to decide — ratings, materials, setpoints, and the standards each is verified against. All of it is free to read without an account and published under CC BY-SA 4.0.
A standard usually carries several topics, so most of the entries below also appear under neighbouring subjects. The topics each one carries are listed on its own page.
Automatic dry-pipe sprinkler systems designed to NFPA 13, in which the piping downstream of a dry-pipe valve is held under supervisory air or nitrogen because the piping is exposed to freezing. Covers the decisions that exist only on a dry system: the dry-pipe valve and its trim, the quick-opening device, the supervisory gas source and its pressures, water delivery time, pitch and low-point drainage, the corrosion consequences of a wet-and-dry pipe interior, the provisions for piping in refrigerated spaces, and the trip test and 24-hour air leakage test that prove the installation.
