scope:

This standard encompasses the design and performance requirements for plastic pipe and fittings in light hazard occupancies for use in automatic wet sprinkler fire protection systems. The intent is to determine:

• That specific pipe and fittings are capable of maintaining sprinkler system integrity and performance during a fire.

• If one of the intended uses of the plastic pipe and fittings is in a hybrid sprinkler system using internally coated steel pipe (i.e. plastic pipe connected to internally coated steel pipe), evaluation of the plastic pipe and fittings under this standard shall include chemical compatibility testing with all certified manufacturer applied internally coated steel pipe (i.e. internally coated by the manufacturer).

Certification standards are intended to verify that the product described will meet stated conditions of performance, safety, and quality useful to the ends of property conservation.

Plastic pipe and fittings examined in accordance with this standard may be certified for unexposed (shielded) or exposed service in light hazard occupancies.

Products certified for unexposed use require a permanently installed non-combustible barrier with a minimum 15 minute rating in accordance with ASTM E119. Alternatively, pipe and fittings discussed in this standard may be used with a certified fire resistant barrier evaluated in accordance with Standard 1636, "Fire Resistant Barriers for use with CPVC Pipe and Fittings in Light Hazard Occupancies". Only plastic pipe and fittings tested with a specific fire resistant barrier in accordance with Standard 1636 may be used.

Products certified for exposed use may be used exposed when installed in accordance with the manufacturer's installation instructions and all of the following criteria are met:

• Occupancy must be covered by an HC-1 Hazard Category

• Sprinklers must have quick response thermal sensing elements.

• Sprinkler systems must be wet pipe type

Plastic pipe and fittings certified to this standard have not been evaluated for use in seismically active areas.

Purpose

This standard states certification requirements for plastic pipe and fittings in light hazard occupancies for use in automatic wet sprinkler fire protection systems.

Testing and certification criteria may include, but are not limited to, performance requirements, marking requirements, examination of manufacturing facility(ies), audit of quality assurance procedures, and a surveillance program.
