Seal Classification Overview
Indicative Security Seal
Seal that is designed and manufactured of material that can easily be broken by hand or by using a simple snipping tool or shears.
Security Seal
Seal that is designed and manufactured of material that provides limited resistance to unauthorized access and requires lightweight tool for removal.
High Security Seals
Seal that is designed and manufactured of material such as metal or metal cable with the purpose to delay intrusion. High security seals generally must be removed with heavy bolt cutters or cable cutters.
The physical strength of the seals is determined by a Tensile, Shear, Bending, and Impact Test.
Mechanical tests – for the classification of security seals, the following must be tested:
- a) Impact test:
To determine impact resilience at 18 °C and -27 °C, an impact test must be carried out. The impact test takes place in three phases. In each phase, a defined force must be exerted on the seal five times (15 times in total). - b) Pull test:
To test the strength of the closure mechanism of a seal, a pull test must be carried out. - c) Bend test
To determine the resilience of a seal under a bending load, the bending test must be carried out (to determine the strength required to bend the seal by 90° within 3 seconds). - d) Shear test:
To test the resilience of a seal to slicing with a cutting blade, such as bolt cutters, a shear test must be carried out.
Important: All Security seals must be checked to indicate all sorts of manipulation.
