ISO Mechanical Seal Standard 17712:2013 Becomes Effective May15th, 2014

The Department of Homeland Security (DHS), USA, has advised that the International Standards Organisation (ISO) published a new version of ISO 17712 on 15 May 2013. The new version is a further evolution of ISO’s standard for Mechanical Seals, first issued as a Publicly Available Specification (PAS) in 2003.

A new ISO seal standard (ISO 17712:2013) goes into effect  as of May 15, 2014. The new standard states that seals compliant with the previous standard (ISO 17712:2010) will no longer be compliant with the new standard unless those seals are backed by an accredited third party certificate or letter regarding the revised tamper evidence and certification provisions.

The new edition addresses tampering via third party process inspections as part of the manufacturers’ ISO 9001 quality operational procedures.

ISO 17712 no longer requires third party laboratory testing against specific tamper-related criteria.  Instead, the requirement for tamper-related quality procedures include internally-generated and internally-managed tests of tamper evidence as part of a manufacturers’ documented quality program like ISO 9001.

A manufacturer may choose to conduct the tamper evident testing in-house or employ a third party laboratory. In any case the testing would be against the manufacturers’ test protocol and specification. Since Clause 6 has neither tamper-evident test procedures nor a requirement for accredited testing, an outside lab cannot certify conformance with ISO 17712 Clause 6. A third party lab in such a situation simply provides a lab report to its customer.

Manufacturers that wish to offer 17712-compliant seals in the future must establish tamper-mitigation procedures for the design and manufacturing processes. Auditable processes must assure explicit attention is given to tamper issues in design and manufacturing.

Effective May 15, 2014 compliance with the tamper-evident aspects of the new standard requires documentation such as a certifying report or letter from auditors accredited in accordance with ISO 17020.  ISO 17020 applies to accreditation for ISO 9001 quality inspections.
