MIL-STD-1540D
TABLE 1
FACTORS TO CONSIDER WHEN ESTABLISHING TEST REQUIREMENTS
Criticality to mission Sensitivity to environment Severity of environment
Knowledge or uncertainty of environment
Environmental time profile
Similarity to previously qualified articles Ability to analyze vs. design margins Maturity of technology
Maturity of production line
Level of assembly vs. simulation, e.g. tubing and wiring vibration tested at higher levels of assembly
Product complexity
Cost of repair and retest for problems found at higher levels of assembly
Use of qualification articles for flight-alternative strategies
Benefits of dedicated qualification articles
-Fatigue life verification for repeated acceptance test of flight articles
-Available test article to evaluate upgrades/modifications
-Available testbed to evaluate mission anomalies
-Greater ability to prove design robustness
Simulation of mission environments
Prior experience with statistically significant sample of similar products and their performance variability
Training and experience of manufacturing, assembly integration and test personnel
Use of automated vs. operator performed manufacturing operations
Manufacturing process controls proven to produce defect free products of similar designs and complexity
