The false deck panels covered by this document are intended for use as a component of the false deck system that performs numerous functions in Navy shipboard environments. The false deck panels interface with the false deck support system to provide a level walking surface free of trip and slip hazards to ensure safety of personnel. The false deck panels meet Navy fire performance requirements and provide electrical safety in accordance with S9086-VG-STM-010/634, Naval Ships' Technical Manual (NSTM) Chapter 634, Deck Coverings, General and S9086-KC-STM-010/300, NSTM Chapter 300, Electrical Plant, General when utilized in electronics spaces and allow cable penetrations to support power connections to electrical equipment. This specification supersedes any reference to NAVSEA Drawing 803-6397418, Nomex Honeycomb False Deck Panel Requirements. False deck panels can be classified into types, classes, forms, groups and areal weights. The type is related to the level of combustibility of the materials used in the false deck panels. Type I is fabricated from any combustible material, and type II is manufactured using only non-combustible materials in accordance with ISO 1182. The class is related to whether the wear surface on the panel is in accordance with MIL-STD-1623. A class 1 material will meet the fire performance requirements for interior finish material and furnishings whereas class 2 does not. The form of the false deck panels is defined as a finished or unfinished panel. The form 1 is unfinished and can be cut to size with whereas the form 2 is a smaller panel with edges that are fabricated to fit into the flexible infrastructure system. The group of the false deck panel defines whether the panels are to be installed in electrical or nonelectrical spaces. Group 1 provides safety inspection from accidental exposure to electrical potential in electrical spaces whereas group 2 panels are considered general-purposed for installation in non-electrical spaces. The areal weight of the panels comes in three levels from 1 to 3. Areal weight 1 is the lightest deck panels and is where weight is most critical, areal weight 2 is where weight is less critical, and areal weight 3 is where weight is not critical. The areal weight levels are defined by specific areal weight density values.
