Better understand the requirements for design, installation, testing, and maintenance of water spray fixed systems.

Industrial fire protection depends on the proper operation of water spray fixed systems. Keep fire protection systems up to code and ready to respond with NFPA 15, Standard for Water Spray Fixed Systems for Fire Protection. Reflecting the latest technology, test data, and field experience, this standard covers the design, installation, maintenance, and test requirements for fixed water spray systems.

A key change to the 2027 edition is added provisions for weep holes as part of auxiliary drains in fixed spray systems.
