scope:

This standard encompasses the design and performance requirements for pipe rehabilitation systems for use in underground fire service water mains. Rehabilitation may be considered for all pipe sizes within the size ranges addressed in the FM Approval Standards outlined in Section 1.2.2. Rehabilitation of pipe outside the allowed size ranges is outside the scope of this standard. In cases where metric sized are to be examined for Approval, test criteria comparable to the United States equivalent size shall be used.

Requirements for the pipe rehabilitation systems addressed in this standard are for use in the rehabilitation of existing underground piping systems for fire protection service.

Approval is limited to rehabilitation systems / sizes which have a rated working pressure of at least 150 psi (1035 kPa).

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

Non-Structural pipe-lining systems are not addressed in this standard.

Purpose

This standard states Approval criteria for pipe rehabilitation systems for use in underground fire service water mains. Rehabilitation of already installed underground pipe lengths / sections is a means to extend the useful life of existing 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 follow-up program.
