Introduction

Standard Evolution and Technological Breakthroughs

Technical Elements	2011 Edition	2022 New Edition
Applicable Objects	Traditional Optical Instruments	Optical and Photonic Instruments (including electronic components)
Test Gas Concentration	SO₂25±5℃	SO₂35±2℃+Humidity Stratified Control

Analysis of Core Test Requirements

The test is divided into two categories: Method 41 (SO₂) and Method 42 (H₂S):

Severity level refinement: The sulfur dioxide concentration is set to five levels of 15-30cm³/m³, which is closer to the actual military data

State control: Safety test items are added to the working mode to verify the strong corrosion protection capability
of electronic components

Implementation Guidance and Suggestions

For the actual application of shipborne optoelectronic equipment:

The spray tempering system in Appendix A is preferred to eliminate local condensation
RF devices should be subjected to continuous 48h survivability testing according to Method 42 Level 3
