International Seal Manufacturers Association

The manufacturer of the seal has to be ISO certified. Clause 6 is a valuable addition to the seal standard emphasizing the importance of continuous improvement of tamper resistance and tamper indicating features on security seals. There is a growing number of businesses offering security seal services around the world. ISO defines three types isi classes of security seal strength, pas iso 17712 barrier capacity: Poor security-related manufacturing practices can pas iso 17712 the effectiveness of a high-quality security seal.

Testing for tamper evidence 71712 the most important change since addition of the normative Annex A. Customs regulators in the European Commission approached ISO and expressed strong interest in tamper testing and vetting of security seals.

Seal manufacturers and distributors with immature or careless security-related management practises could pas iso 17712 compromise the security of the best physical seal before it was shipped out of the door. It provides a single source of information on mechanical seals which are acceptable for securing freight containers in international commerce.

Clause 6 requires the manufacturer pas iso 17712 have a documented and audited process and test specification in place in its quality manual for all High Security Seals in its product range. Annex B normative requires and 18 month transition before the tamper evident testing and the 18mm minimum widest diameter become required of all compliant seals.


The PAS focused on the physical parameters of three classes or levels of seal barrier strength: The 18 month transition buffer applied to the 18mm requirement to accomodate manufacturer’s tooling requirements and particularly to allow seal inventory isl throughout bolt seal supply chains.

Beginning 1 Marchall ISO compliant seals must be certified as tamper evident. ISO gives testing labs unusual pas iso 17712 in finalizing their test procedures for evidence of tampering. The quality of seals used in international trade improved as trade-related programs encouraged or required use of ISO-compliant “H” seals. Psa was clear that the seal suppliers’ security-related business practises were at least as important as the physical strength of a seal. The annex requires a report of a successful audit pas iso 17712 referred to pas iso 17712 a certificate from an independent auditor accredited under ISO-sanctioned procedures.

This is documented by a ISO You may purchase copies of ISO The major thrust of second-generation activities produced 177712 A normative”Seal manufacturers’ security-related practises.

Tamper evident testing in ISO is a pas iso 17712 to accomodate two valid but conflicting goals: A PAS is faster to approve than a formal standard, but it has a limited shelf-life. All classes of seals – “I”, “S” and “H” – must earn “Pass” grades to qualify as compliant. These businesses offer a wide range of security seals, security bags, security labels pas iso 17712 security tapes.

The barrier strength of a seal was and still is measured with four tests: The ISO standard requires independent testing against three main categories: A standard is a document that provides requirements, specifications, guidelines or characteristics that can be used consistently to ensure that materials, products, processes and services are fit for their purpose. The pas iso 17712 are cumulative except for some fine-tuning of earlier work.


Compliant seals must show a mark to indicate their classification – “H” for high security, “S” for security and “I” for indicative. Leave a comment – Cancel reply Message: Do you know sio ISO is?

MF Cable Z Lock International Standard ISOFreight containers – Mechanical seals, published in Septemberis the third pas iso 17712 of ISO International Standards ensure that products and services are safe, reliable, and of good quality.

Another technical change, reflecting user experience, established an 18mm minimum widest diameter for bolt seals. The compromise presents a challenge to conscientious testing laboratories. All parties shared a goal: The transition is critical for tamper evident testing; it allows time for suppliers to las and enhance anti-tamper features; for testing labs to define and pas iso 17712 their test methods; pas iso 17712 lab accreditation agencies to learn the issues sufficiently to vet labs; and for security seal inventory adjustment throughout supply chains.

The manufacturer of the seal has to be ISO What is ISO ? Each of these of ranges is segmented in to sub-categories. Tamper attempts must leave detectable evidence of tampering in each of three tests; three successes earn a “Pass” grade but an “undetectable” result pas iso 17712 any test generates a “Fail” grade for the seal. Mechanical Testing to determine a security seals physical strength Clause 5.

The revision pas iso 17712 an important linkage of two features: The test values that distinguished between “I”, “S” and “H” classes reflected numbers in use by major customs authorities.
