Environmental Acceptance Testing
This Environmental Acceptance Test Specification establishes the minimum test
and documentation requirements to be met by NASA and its contractors in the
environmental acceptance testing of hardware, both Government-furnished and
contractor-furnished, for use in SSP applications.
This document specifies the overall requirements applicable to environmental accep-
tance testing conducted to detect manufacturing flaws and workmanship defects in
flight hardware, flight-type test hardware, and selected ground support equipment that
cannot be readily detected by normal inspection techniques. Section 2.0 specifies the
criteria for the selection of hardware to be tested and the responsibility for hardware
selection. Section 3.0 specifies the manner in which environmental acceptance testing
is to be conducted. Section 4.0 details the extent to which environmental acceptance
testing is applicable to qualification testing; and Section 5.0 specifies the general
requirements, test procedures, and tolerances for acceptance vibration, thermal, and
thermal/vacuum testing of flight hardware, flight-type test hardware and ground support
Environmental acceptance test requirements are applicable to all flight hardware, flight-
type test hardware, and ground support equipment for SSP applications selected in
accordance with the criteria in Section 2.0 of this specification. The environmental
acceptance testing on the selected level of assembly shall be accomplished after
manufacturing and inspection is complete, and prior to the next assembly level or sub-
sequent scheduled usage.
Qualification testing consists of those tests conducted to verify that flight hardware and
associated ground support equipment meet design specification requirements neces-
sary to assure operational suitability at anticipated environments for their use cycles.
For the purpose of this document, acceptance testing consists of those tests conducted
to determine that a component is capable of meeting performance requirements pre-
scribed in the purchase specification or other documents specifying what constitutes
adequate performance capability for the item in question.
