Seal Tests

To classify security seals, the following mechanical tests are performed on the seals:

1. Multiplicity testing:

This test should be performed between 18°C and -27°C to determine the impact resistance. The multiply test is carried out in three stages, in each stage a certain force must be applied to the seal 5 times.

1. B) Tensile test:

A tensile test should be performed to test the strength of the closing mechanism of a Seal.

1. C) Bending test:

To determine the strength of the seals under bending pressure, a bending test should be carried out (to determine the resistance required to bend the seal 90 degrees in 3 seconds).

1. D) Shear test:

A shear test should be performed to determine the flexural strength of the seals.

Important Note: All safety signs should be checked to indicate types of tampering.

Key considerations in the design of security seals

– Security seals must indicate whether the sealed device has already been opened

– Resistance to prevent tampering or delay of the sealed device.

-Have features that indicate unauthorized intervention with security seals.

– Resistance to use spare parts

-Prevent accidental breaking of Seals in a sealed place
