Most customer-specific cleanliness standards adhere to or are modeled after ISO 16232, the familiar industry standard for technical cleanliness. Developed primarily by the OEMs and Tier-One suppliers, customer-specific specifications are written to control the cleanliness of a system and are cascaded down to lower tier suppliers.

However, many customer-specific standards go too far by prescribing inspection procedures that are component specific or one-size-fits-all instead of allowing an effective procedure to be established. The industry standards for technical cleanliness are generic by design. When manufacturers fill in the details that industry standards leave unspecified, suppliers may be forced to violate key requirements, leading to negative results.
