Standard Environmental Testing Practices 
A manual on procedural requirements for per-
forming certain environmental tests on space flight 
equipment has been issued by the Jet Propulsion 
Laboratory. Although the manual is intended for use 
by subcontractors and laboratory personnel, it pro-
vides useful information for designers of test equip-
ment; it is of particular interest to quality-control 
and production engineers as well as manufacturers of 
components and systems for particular environments. 
The first section of the manual indicates the ap-
plicability of a group of standard testing procedures 
and lists typical tests and test environments; refer-
ence to other pertinent specifications and publications 
are included in this section. 
The second section systematically discusses re-
quirements for test laboratory facilities, measurement 
and control, types and methods of testing, test fix-
tures, detailed test procedures, test consistency, and 
test abort decisions. Included in this section are de-
tailed the procedural requirements for the following 
tests: 1) forced vibration; 2) acoustic reverberant; 
3) shock; 4) static acceleration; 5) thermal-vacuum; 
6) humidity; 7) package drop; 8) explosive atmos-
phere; 9) temperature. Each test is systematically 
described under typical headings such as: 1) test 
system requirements; 2) test levels and criteria; 
8) test article mounting; 4) test article protection 
methods; 5) test tolerances; 6) tolerance of test 
conditions.
The third section gives details relating to test docu-
mentation; guidelines are listed for adequacy of 
reporting and describing test procedures, with special 
emphasis on the systematic presentation of all infor-
mation relating to a test. For example, a list of 26 
requirements is indicated as appropriate for descrip-
tion of a test procedure. 
The final section lists procedural requirements for 
performance of the test within a given organization. 
Emphasis is placed on the recognition of hazards 
and the necessity for personnel safety as well as 
protection of the item under test; methods for control 
of the cleanliness of the test facility and test equip-
men are listed. An effective program for calibration 
of test equipment is mandatory.
