ASTM F1298-90(1995)e1

Standard Specification for Flexible, Expansion-Type Ball Joints for Marine Applications

SCOPE
1.1 This specification covers the design, manufacture, and testing of ball joints utilized for accommodating thermal expansion and contraction, or mechanical movement of a pipeline carrying fluid. The ball joints are intended for use in systems operating above 0°F (18°C).
1.2 The following precautionary caveat pertains only to the test methods portion, Section 7, of this specification:  This standard does not purport to address the safety problems 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 limitations prior to use.
