ASTM F1020-86(2011)

Standard Specification for Line-Blind Valves for Marine Applications

ABSTRACT
This specification provides the minimum requirements for design fabrication, pressure rating, and testing for line-blind valves. The materials for spectacle plates, bolting and body shall be determined. Each valve body shall be subjected to a hydrostatic test.
SCOPE
1.1 This specification provides the minimum requirements for design fabrication, pressure rating, and testing for line-blind valves.  
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.  
1.3 The following safety hazards caveat pertains only to the test methods portion, Section 5, 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 limitations prior to use.
