This document provides a test procedure for use with multi-exciter and multi-axis vibration test systems. The vibration test is intended for general application to components, equipment, and other products, hereinafter referred to as “specimens”, that may be subjected to dynamic environments that could arise during an equipment life cycle. Although this document is mainly intended for vibration testing the procedure can also be applied to certain types of shock and transient tests. The test procedure set out in this document is applicable where a specimen is required to demonstrate its adequacy to resist specified vibration, shock and transient conditions, without unacceptable degradation of functional or structural performance. The test procedure has significant similarity to test procedures of other IEC 60068 -2 documents and encompasses the same range of vibration and shock excitation types. This document is applicable to specimens which may be subjected to vibration, shock and transient conditions resulting from transportation and/or operational environments, for example in aircraft, space vehicles and land vehicles. It is primarily intended for unpackaged specimens. It is applicable to specimens in their transportation container when the latter may be considered as part of the specimen itself. The test method and associated techniques addressed within this document are primarily intended for use with multiple electrodynamic or servo-hydraulic vibration generators along with an associated computer-based digital control system to control of the specimen excitations. This document encompasses two testing approaches, commonly referred to as Multi-Exciter Single-Axis (MESA), and Multi-Exciter Multi-Axis (MEMA). These are:
