Introduction

Analysis of core changes in the new version of the standard

Comparison dimensions	2022 version	2010 version
Scope of application	Optoelectronic integrated devices	Traditional optical instruments
Condensation test requirements	Relative humidity control in stages	Single humidity limit
Acceptance criteria	MTBF comprehensive evaluation system	Single state verification

Test engineering implementation specifications

High-precision microscopic imaging module requires adaptability improvements when working in the harsh level 04 state:

The lens group should be treated with anti-condensation coating
The temperature compensation circuit needs to be activated when performing the temperature gradient test
The temperature tolerance of the critical control point in the high temperature stage is ±2℃

Typical disposal suggestions

Preferably use conditional test method 15 to verify the sudden change adaptability of waterproof optical instruments
Loose particle analysis (PIND) detection is required before implementation of high-complexity equipment
The circulating water classification can be relaxed for structural components with Damping coefficient＞0.85
