MIL-STD-3020

Abstract

This standard provides the fire resistance test method and acceptance criteria, following shock testing, for approval of N-Class and AN-Class divisions and their penetrations on U.S. Navy surface ships. The fire resistance test method described herein supersedes fire resistance test method requirements of Appendix A in MILPRF- 32161, and American Bureau of Shipping (ABS) Naval Vessel Rules Part 1, Chapter 2, Section 1. This standard is applicable to fire resistant divisions constructed from steel, aluminum, and polymer composite structures. This standard does not address ignitability, surface flame spread, heat release rates, smoke density, fire gas toxicity or other material fire performance limits or basic system/component design requirements which may be imposed by other documents and the Naval Technical Authority (NTA). <b><u>Intended Use:</u></b> This standard provides the fire test procedures and acceptance criteria for qualification of fire resistant divisions and their penetrations on U.S. naval surface ships. It is intended to satisfy the fire resistance requirements for fire resistant divisions and their penetrations in accordance with ABS NVR Part 1, Chapter 2, Section 1. This standard presumes that the detailed division or penetration system development and qualification is accomplished by a ship design activity, such as a commercial shipbuilder, under contract to the government, or material supplier, referred to herein as the "proposer". <br>
