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 FM Approved manufacturer applied internally coated steel pipe (i.e. internally coated by the manufacturer).

Approval 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 FM Approved for unexposed or exposed service in light hazard occupancies.

Products FM Approved 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 fire resistant barrier FM Approved in accordance with Approval 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 FM Approved for exposed use may be used exposed when installed in accordance with the manufacturer's installation instructions and FM Global Loss Prevention Data Sheets.

Plastic pipe and fittings FM Approved to this standard are not permitted in seismically active areas in accordance with FM Global Loss Prevention Data Sheet 2-8.

Purpose

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

Approval criteria may include, but are not limited to, performance requirements, marking requirements, examination of manufacturing facility(ies), audit of quality assurance procedures, and a follow-up program.
