This part specifies the pollution test conditions, condition tests and environmental test marks. "Contamination" as used in this section means exposure of corrosive chemicals to optical instruments. This section applies to optical instruments, instruments incorporating optical components and optical components. This section does not apply as a normal production control. The purpose of this test is to investigate the resistance of instruments, especially their surfaces, coatings or synthetic materials, to exposure to reagents for a short period of time. The test is usually only used as a reference when selecting materials or components for instruments that may be contaminated during use.
