Covering the assessment of suitability for use of equipment and materials by airborne chemical concentration
IEST, the Secretariat to ISO Technical Committee 209, Cleanrooms and associated controlled environments, says ISO Draft International Standard (DIS) 14644-15: Assessment of suitability for use of equipment and materials by airborne chemical concentration is now available.
Part 15 of the ISO 14644 Standards Series was spun off from the original equipment standard (ISO/DIS 14644-14) to focus on suitability by airborne chemical concentration.
The new standard includes requirements and guidance for assessing the chemical airborne cleanliness of equipment and materials which are linked to ISO 14644-8. ISO 14644-8 establishes the levels of air chemical cleanliness in terms of airborne concentrations of specific chemical substances (individual, group or category) and provides a protocol to include test methods, analysis, and time-weighted factors within the specification for the level.
