ASTM F991M-04(2008)

Standard Specification for Docking/Drain Plug and Boss Assemblies [Metric]

ABSTRACT
This specification provides design, construction, and purchasing criteria for docking/drain plug and boss assemblies. Assemblies are intended for installation in shell, rudder, and tank bottom plate. Assemblies shall be installed at the lowest point of a tank or rudder for draining during dry docking. Docking plugs and bosses shall be classified as follows: type I - docking plug and bosses for plating from 8 to 15 mm, and type II - docking plug and bosses for plating greater than 15 to 38 mm. The procedure for installing docking/drain plug and boss assemblies are presented.
SCOPE
1.1 This specification provides design, construction, and purchasing criteria for docking/drain plug and boss assemblies.  
1.2 Assemblies are intended for installation in shell, rudder, and tank bottom plate from 8 through 38 mm.  
1.3 Assemblies shall be installed at the lowest point of a tank or rudder for draining during dry docking.  
1.4 The values stated in SI units are to be regarded as the standard.
