Stone Adhesion, Impact Drop, Heat Test, Pull Test

AnchorCert Analytical is able to carry out a wide range of durability tests. These include:

STONE ADHESION
To assess whether stones in stone set articles are adequately set or glued to the setting by using a tape adhesion method and/or ultrasonic stone adhesion procedure.

HEAT TEST
Determines the reaction of articles to severe temperature changes. Articles are exposed to drastic fluctuations in temperature, then the surface is examined for signs of blistering or detachment under 10 x magnification.

IMPACT DROP TEST
Establishes the resistance to adhesive failure during impact on stones (includes glass, plastic and metal posts and inserts) glued in the settings.

PULL  TEST
Establishes the strength at which a bracelet/necklace will break apart. A child's item should not break away at below a certain Newton strength as otherwise it could lead to strangulation.

These tests can be carried out within 5 working days.

To enquire about any other durability tests not listed above then please contact testing@theassayoffice.co.uk or call 0871 871 6020.
