Abstract:

This specification describes requirements and test methods for the qualification of Polyamide 11 (PA 11) bodied mechanical fittings for use with outside diameter controlled PA 11 pipe, and nominal 2 pipe size (IPS) and smaller. In addition, it specifies general requirements of the material from which these fittings are made. Performance requirements shall include tests to determine elevated temperature sustained pressure, tensile strength, in-line fitting, mechanical saddle fittings, temperature cycling, and joint constant tensile load.

Scope:

1.1 This specification describes requirements and test methods for the qualification of Polyamide 11 (PA 11) and Polyamide 12 (PA12) bodied mechanical fittings for use with outside diameter controlled Polyamide 11 (PA 11) and Polyamide 12 (PA12) pipe, nominal 2 pipe size (IPS), and smaller complying with Specification D 2513. In addition, it specifies general requirements of the material from which these fittings are made.

1.2 The test methods described in this specification are not intended to be used as routine quality tests.

1.3 This specification covers the types of mechanical fittings covered in 3.2.1.

1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

1.5 The following safety hazards caveat pertains only to the test methods portion, Section 7, of this specification. 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 determine the applicability of regulatory requirements prior to use.

1.6 The text of this specification references notes and footnotes, which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this specification.
