ISO14644 Part 13


A new ISO 14644 cleanroom standard has reached the final draft stage. This is:
ISO 14644-13 - Cleanrooms and associated controlled environments -- Part 13: Cleaning of surfaces to achieve defined levels of cleanliness in terms of particle and chemical classifications.

This standard gives guidance on the selection of cleaning methods to achieve specified cleanliness levels. For the selection procedure, the aspects of surface description, cleanliness specifications, types of contamination, cleaning techniques, material compatibility, and assessment methodology are taken into consideration.

The standard provides guidance on the assessment of cleaning methods for achieving the required surface cleanliness by particle concentration (SCP) and surface cleanliness by chemical concentration (SCC) classes and which techniques should be considered to achieve these specified levels.

Copies of the draft are available from national standard organizations.
