ASTM E2377-04

Standard Specification for Shelter, Electrical Equipment, Lightweight

ABSTRACT
This specification covers two types of lightweight electrical equipment shelters designed for transport on both the M1037 and M1097 high mobility multipurpose wheeled vehicle (HMMWV) by rail, air, marine, and highway when mounted or dismounted from their vehicles. The shelters will be of the following types: Type I —shelters without tunnel(17-2-0035-1); and Type III —modified general-purpose shelters with tunnel (17-2-0035-3). Shelters shall undergo rigid verification procedures to inspect their conformance to requirements pertaining to physical performance, environmental performance, transportability performance, identification, toxicity, and flame resistance.
SCOPE
1.1 This specification covers two types of lightweight electrical equipment shelters designed for transport on both the M1037 and M1097 High Mobility Multipurpose Wheeled Vehicle (HMMWV). These shelters are transported by rail, air, marine and highway when mounted or dismounted from their vehicles.
1.2 ClassificationThe shelters will be of the following types, as specified (see ).
1.2.1 Type IShelter, Electrical Equipment, Lightweight (w/o Tunnel, 17-2-0035-1).
1.2.2 Type IIIShelter, Electrical Equipment, Lightweight, Modified, General Purpose (w/Tunnel, 17-2-0035-3).
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parenthesis are for information only.
The following safety hazards caveat pertains only to the test required portion, Section , of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.
