This specification covers engineering and design criteria for rigid wall relocatable structures (RWRSs) which shall be used for designing expandable and nonexpendable RWRSs. RWRSs shall be manufactured from recovered materials, wherein intimate contact of dissimilar materials shall not be allowed (to prevent galvanic corrosion), all components shall be adequately protected from corrosion, and the materials used shall not cause any skin irritation or injury to the person handling the material during transportation, operation, or maintenance of the equipment. Tests for compatibility, air transportability, ground mobility, rail transportability, forklift handling, erecting and striking, air tightness, blackout, humidity resistance, marine atmosphere, temperature, solar load, temperature shock, heat transfer, blowing sand, sunshine (ultraviolet effects), flame resistance, fungus resistance, squareness, panel flatness, roof loads, floor loads, door loads, panel attachment points, leveling devices, lifting and towing provision strength, tow and dragging simulator, flat and rotational drop (with or without skids), drop shock, impact resistance, electromagnetic interference provisions, water tightness, and lift shall be performed and shall conform to the requirements specified.
1.1 This specification covers engineering and design criteria required for the development of rigid wall relocatable structures (RWRS) and shall be applied to the design of expandable and nonexpandable RWRSs. This specification applies to present engineering and design requirements for effective RWRSs that are operable in a variety of environments without degradation and are capable of all specified transport modes. This specification shall be applied to the design of expandable and nonexpandable RWRSs. This specification is a conversion of a military standard that was approved by all departments and agencies of the Department of Defense.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 The following safety hazards caveat pertains only to the test required portion, Section 10, of this specification. This specification 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 specification to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
