Portable Test Enclosure Specification

General This specification outlines the requirements for the construction of a portable test enclosure (PTE) for land‐ based and at‐sea use. The PTE will be lifted on and off the deck of a vessel by a crane or a forklift, and properly secured to the vessel’s deck. The PTE will be a stand‐alone container connected to land‐based or ship’s electrical service and provides a weather‐tight climate controlled environment. The requirements provided below dictate the minimum acceptable performance specifications necessary for the PTE.

Applicable Documentation The following standards and documentation shall be used to determine the acceptable design and construction of the PTE. The U.S. Government, to be further referred to as the customer, will be the sole inspection authority for the validation of these standards.
