The high temperature fire insulation shall be assessed by the Navy and Marine Corps Public Health Center
31、(NMCPHC) using the administrative Health Hazard Assessment (HHA). A flowchart for this process can be found as enclosure (1) of BUMED INST 6270.8.

The high temperature fire insulation shall be certified for and assigned a usage category of either “
33、Permitted” or “Limited” in accordance with the Material Control Program chapter of NAVSEA S9510-AB-ATM-010 (see 4.6 and 6.6). 3.3 High temperature insulation panel. 3.3.1 Dimensions and tolerances.

Types I, II, and III high temperature insulation panels shall have facing materials as described in 3.4.1. 3.4.1 Facing materials. 3.4.1.1 Type I and Type II. Type I and Type II
38、shall have a facing material which, when separated from the insulation, shall have a breaking strength not less than the values specified in table III. The high temperature fire insulation panel shall be attached to the facing material using an adhesive that meets the fire tests as specified in MIL-
39、A-3316, Class 1, Grade A adhesive. TABLE III. Facing requirements.

Type III, Classes 1 through 4, shall have a facing material conforming to the req
40、uirements of MIL-A-23054, or to the requirements of ASTM C1139, Type III. The high temperature fire insulation panel shall be attached to the facing material using an adhesive that meets the fire tests as specified in MIL-A-3316, Class 1, Grade A adhesive. 3.4.2 Facing alignment. In the event that t
41、he facing material does not cover the entire surface of the high temperature fire insulation panel, the uncovered portion of the panel shall not extend farther than 18 inch from any edge. The facing shall not extend over the edge of the panel more than 18 inch. 3.4.3 Facing material adhesion. The fa
42、cing on Types I, II, and III shall have a peel strength of not less than 1 lb/in2. 3.4.3.1 Test notes and observations. Because of the various types of insulation material and attachment methods used, variations in peel strengths may be observed. Some backing materials may not have sufficient struct
43、ural strength to withstand more than 1 pound of separation force from the cemented facing material. In these instances, it may be observed that the insulation backing material has separated, and a thin layer of matt may be seen attached to the facing. This is not a failure of the adhesive used; it i
44、s structural failure of the backing material. Failure of the backing material should be noted in the test report. 3.5 Performance characteristics. 3.5.1 Thermal conductivity of high temperature insulation panel. The thermal conductivity (k) of the Type I high temperature fire insulation panel shall

The fire-containment assembly, bulkhead assemblies with attached insulation, shall have withstood the fire endurance test without passage of flame for a time period equal to that for which the classification is desired, and b. Transmission of heat through the assembly during the fire end
49、urance test period shall not have raised the average temperature on its unexposed surface more than 250 F (139 C) above its initial temperature, nor the temperature of any one point on the surface, more than 325 F (181 C) above its initial temperature (see 4.4.8.3). 3.5.3.4 Non-combustibility (Type I).
