ISO14644-14

ISO 14644-14:2026 Cleanrooms and associated controlled environments - Part 14: Assessment of suitability for use of equipment by airborne particle concentration is available as an International Standard.

Background

This part of ISO 14644 specifies a methodology to assess the suitability of equipment (e. g. machinery, measuring equipment, process equipment, components, tools) for use in cleanrooms and associated controlled environments, with respect to airborne particle cleanliness as specified in ISO 14644-1. Particle sizes range from 0,1 μm to equal to or larger than 5 μm (given in ISO 14644-1).

This second edition cancels and replaces the first edition (ISO 14644-14:2016), of which it constitutes a minor revision. The changes are as follows:

• updated reference document;
• corrected title in Bibliography;
• removed references that are not mentioned in the text from the Bibliography.

Note 1: Where regulatory agencies impose supplementary guidelines or restrictions, appropriate adaptation of the assessment methodology can be required.

Note 2: Items not covered by ISO 14644-14 include: Assessment of suitability with respect to bio-contamination; Testing for suitability of decontamination agents and techniques; Cleanability of equipment and materials; Requirements on design of equipment and selection of materials; Physical properties of materials (e. g. electrostatic, thermal properties); Optimizing performance of equipment for specific process applications; Selection and use of statistical methods for testing; And protocols and requirements for local safety regulations.
