scope:

This standard encompasses the design and performance requirements for NPS (Nominal Pipe Size) 4 inch through 36 inch nominal size FRC pipe and fittings for use in underground fire service mains, other sizes may be evaluated on a case-by-case basis.

In cases where metric sized FRC pipe and fittings are to be examined for Approval, test criteria comparable to the United States equivalent size shall be used.

FM Approvals will consider FRC pipe and fittings which are designed in accordance to national or international standards, such as the American Water Works Association (AWWA) C-950-13 for Fiberglass Pressure Pipe. Pipe manufactured in accordance with other nationally or internationally recognized standards will be considered on a case-by-case basis. All Approval testing is to be conducted on production samples.

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

This standard is primarily intended for use in Approving fiberglass pipe and fittings. Other Fiber Reinforced Composite materials can be FM Approved under this standard and will be evaluated on a case-by-case basis.

Purpose

This standard states Approval criteria for Fiber Reinforced Composite (FRC) pipe and fittings for underground fire service water mains.

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 surveillance audit program.
