The physical integrity of fabric items is a critical aspect of contamination control.
ESD garment test
Fabric wear is influenced by many factors including the type of manufacturing operation in which it is used, the number of decontamination processes received and any sterilisation cycles.
This variability means that as well as a visual inspection it is often necessary to validate an acceptable garment life for a particular process and to remove the item at the pre-determined maximum number of wear and process cycles regardless of its physical appearance.
If an item fails to achieve the minimum standard set by the various conformance procedures it must be removed from cleanroom use and either repaired or replaced.
