ISO/DIS 14644-3:2016

Test Methods

Published by: 2016-12-16 / 2016-12-16 / 79 pages
This part of ISO 14644 provides test methods in support of the operation for cleanrooms and clean zones to meet air cleanliness classifications and related controlled conditions. Tests for classification of cleanliness are described in ISO 14644-1(classification of air cleanliness by particle concentration and for macroparticles). Other related attribute levels can be determined using ISO 14644-8 (levels of air cleanliness by chemicals), ISO 14644-9 (levels of surface cleanliness by particle concentration) and ISO 14644-10 (levels of surface cleanliness by chemical concentration). Performance tests are specified for two types of cleanrooms and clean zones: those with unidirectional flow and those with non-unidirectional flow, in three possible occupancy states: as-built, at-rest and operational. The test methods, recommend test apparatus and test procedures for determining performance parameters are provided. Where the test method is affected by the type of cleanroom or clean zone, alternative procedures are suggested. For some of the tests, several different methods and apparatus are recommended to accommodate different end- use considerations. Alternative methods not included in this part of ISO 14644 may be used if based on agreement between customer and supplier. Alternative methods do not necessarily provide equivalent measurements.

This part of ISO 14644 is not applicable to the measurement of products or of processes in cleanrooms, clean zones or separative devices.

NOTE: This part of ISO 14644 does not purport to address safety problems associated with its use (for example, when using hazardous materials, operations and equipment). It is the responsibility of the user of this part of ISO 14644 to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.

Specifications for monitoring air cleanliness by nanoscale particle concentration

Published by: 2016-10-27 / 2016-10-27 / 13 pages
This part of ISO 14644 covers the monitoring of air cleanliness by particles in terms of concentration of airborne nanoscale particles.

For monitoring purposes, only populations of particles with a lower size limit of 0.1 microns (100 nm) or less – “nanoscale” – are considered.

The monitoring given in this document is for use mainly in “operational” states.

Note 1 to entry For the purposes of this document, reference will be made to “nanoscale particles”, which here signify all nano-objects having one (nanoplate), two (nanofibre) or three (nanoparticle) dimensions in the nanoscale.

Note 2 to entry It should be noted that the actual behaviour of particles in the cleanroom depends on their sources and physical behaviour.

Note 3 to entry Health and safety considerations are excluded from this document.
