Introduction

Comparison of core revisions of the new standard

Revision dimensions	2010 version	2022 version
Scope of application	Optical instruments	Optical and photonic instruments
Impact test parameters	Excerpted from IEC standards	Fully aligned with GB/T 2423 Series
Test Coordinate System	Gravity Difference Parameter	Uniform Simplified Acceleration Parameter

Classification Analysis of Mechanical Environment Test

Type 30 Impact Test adopts half-sine wave loading mode, and three impacts in each direction of the three axes are strictly evaluated to evaluate the product structural strength. It is recommended to give priority to the key stress parameters of ɡ=500 and duration 5ms.

Test type	Test scenario	Typical application
Free fall (Type 33)	Transport simulation with packaging	Conventional equipment transportation compliance test
Broadband random vibration (Type 37)	Strength verification under complex working conditions	Airworthiness testing of avionics equipment

Recommended implementation procedures

1. Equipment installation strictly follows the fixed standard of GB/T 2423.43 to eliminate fixture resonance interference
2. Composite test specifications need to coordinate temperature/vibration superposition factors, and it is recommended to prioritize FMECA failure mode analysis
3. Industrial equipment periodic inspection according to 1500 high cycle fatigue standard to formulate MRO plan
