ASTM F1020-86(2018)

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 standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

3.1 blank—a solid one-piece circular unit inserted into a pipeline to prevent flow.
3.2 line-blind valve—an assembly consisting of a spectacle plate, bolting, and body, the purpose of which is to provide a
convenient means to align a piping system to an open or positively closed configuration. The assembly is designed to provide a
simplified method of changing over the flow control spectacle plate without the necessity of plate removal from the valve body.
3.3 spectacle plate, (also spectacle blind )—a figure-eight-shaped unit with one end open for flow and the other solid to prevent
flow.
