ISO 17712:2013 is an international standard that sets specific requirements for security seals used to secure cargo containers, trailers, and railcars. It is published by the International Organization for Standardization (ISO) and it provides a framework for the design, testing, and performance of security seals.

The standard includes specifications for materials, construction, and testing of security seals, as well as requirements for tamper-evident features, marking, and traceability of the seals. It also includes guidelines for the selection and use of security seals, and it provides a framework for the evaluation of the performance of security seals.

ISO 17712:2013 is designed to help ensure that security seals used to secure cargo containers, trailers, and railcars are secure and tamper-evident, and it provides a framework for testing and certifying security seals to ensure that they meet specific performance requirements.

It's important to note that, compliance with ISO 17712:2013 is voluntary and it's not mandatory for security seals to meet the standard. However, it's a widely recognized standard and many organizations and countries may require that security seals used to secure cargo containers, trailers, and railcars meet the requirements of ISO 17712:2013 or other standards.
