1. Scope

1.1 This guide establishes procedures for evaluating lining system test specimens under simulated operating conditions.

1.2 Lining systems to be tested in accordance with this guide are intended for use in both new construction and for refurbishing existing systems or components.

1.3 The lining systems evaluated in accordance with this guide are expected to be applied to metal substrates comprising water-wetted (that is, continuous or intermittent immersion) surfaces in systems that may include:

1.3.1 Service water piping upstream of safety-related components,

1.3.2 Service water pump internals (draft tube, volutes, and diffusers),

1.3.3 Service water heat exchanger channels, pass partitions, tubesheets, end bells, and covers,

1.3.4 Service water strainers, and

1.3.5 Refueling water storage tanks and refuel cavity water storage tanks.

1.4 This guide anticipates that the lining systems to be tested include liquid-grade and paste-grade polymeric materials. Sheet type lining materials, such as rubber, are excluded from the scope of this guide.

1.5 Because of the specialized nature of these tests and the desire in many cases to simulate to some degree the expected service environment, the creation of a standard practice is not practical. This standard gives guidance in setting up tests and specifies test procedures and reporting requirements that can be followed even with differing materials, specimen preparation methods, and test facilities.

1.6 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
