Suitability for purity of operating materials and HVAC components

The revised VDI 2083 Sheet 9.1 provides guidance on the cleanliness suitability of operating equipment and room air technology components – from planning to verification. Thus, it helps achieve a specified product quality. The guideline offers a standardized approach for qualifying operating equipment and HVAC components for cleanliness-critical areas.

Operating equipment and room air technology components in cleanrooms must meet special requirements. It must be ensured that they do not introduce or generate unacceptable contaminants into the room – neither during commissioning nor throughout their remaining service life in the cleanroom.

It is advisable to consider the cleanliness suitability of components already during the design of the clean areas, as later replacement often involves considerable effort, costs, and disruptions to the workflow. The assessment of cleanliness suitability is a holistic and partly product-specific testing process. It is necessary to define the objectives of the testing, i.e., the operational parameters of the test object in conjunction with the specific work steps where emissions and contaminants may occur. Furthermore, environmental conditions must be observed for a valid test result, and not least, the available measurement technology itself. VDI 2083 Sheet 9.1 outlines the fundamentals, steps, and parameters of cleanliness suitability, particulate surface cleanliness, and their control.

The publisher of VDI 2083 Sheet 9.1 "Cleanroom Technology - Cleanliness Suitability and Surface Cleanliness" is the VDI Society Building and Building Services (GBG). The guideline was published in January 2021 as a white paper and replaces the December 2006 edition. It can be ordered from Beuth Verlag at a price starting from EUR 123,- (Tel.: +49 30 2601-2260).
