- Scope
- This document describes environmental test methods for optical and photonic dust. This document applies to optical and photonic instruments, including dust tests on components from other fields such as mechanical, chemical and electronic equipment. This document does not apply to tests of abrasive resistance to coarse-grained sand and dust.
- Introduction
Interpretation of core test conditions
Parameters 2010 version 2022 new version Significance of changes Covered areas Optical instruments Optical and photonics instruments Applicable to emerging fields such as quantum optics Allowable deviation of sand and dust concentration ±3% ±2% Improve test reproducibility Detailed explanation of key technical indicators
The test sand and dust must meet the requirement of SiO2≥97%, and the sieve used in production is based on ISO565 standard. The key particle size composition is: 71μm (28%), 100μm (15%), 45μm (57% remaining), and the
Equipment selection and optimization plan
Test chamber must be equipped with a three-stage circulation system:- Wind speed adjustment range 0.1~3m/s
- Temperature control accuracy ±1℃
- Photoelectric concentration monitoring ±0.5g/m3
Implementation difficulties and solutions
New energy vehicle lens test case: The cargo transportation environment must simulate the arid climate in the west. The solution adopts a step-by-step exposure method with a mutation frequency of ≤3 times/hour...Comparison table of new and old systems
