Some national standards bodies or libraries may provide free or low-cost access to ISO standards, including ISO 18593. However, be aware that these may be limited to viewing only, and you may not be able to download a copy.

ISO 18593 is an international standard for "Cleanrooms and associated controlled environments - Part 1: Vocabulary" and also provides guidance on the measurement of airborne particle concentration in cleanrooms and clean zones.

Hope this helps!

You can purchase and download ISO 18593 from the official International Organization for Standardization (ISO) website or through authorized distributors.
