Here’s a detailed breakdown of what the standard covers:
When critical electronics, propulsion components, or auxillary systems are exposed to naval-grade shock, they must remain operationally available without time restrictions. Key Shock Grades and Severities in BR 3021
Unlikely. Standards evolve. The 1988 version is almost certainly superseded. Using an outdated standard may lead to incorrect test temperatures or equipment specifications. Always get the latest active version.
