ASTM F994-86(2001)

Standard Specification for Design and Installation of Overboard Discharge Hull Penetration Connections

SCOPE
1.1 This specification covers carbon steel overboard discharge hull penetrations for system piping of NPS 1 through NPS 24 (see Note 1).
Note 1—The dimensionless designator NPS (nominal pipe size) has been substituted in this standard for such TRADITIONAL terms as nominal diameter, size, and nominal size.  
1.2 The minimum pipe schedule and reinforcement dimensions presented in Tables 1-6 are based on specifications in 46 CFR, 56.50-95 and Navy Design Data Sheet 100-1.  
1.3 This specification does not include sea chest penetrations.  
1.4 This specification does not include penetrations in protective plating.
