Is there any specification on the zinc plating of the saving time latches?

The zinc plating process is the electrochemical depositon of zinc.

There are 2 types: natural white zinc or zinc bichromated by finishing with a chromation.

Saving time latches can be held in normal non-tropical environments, so the temperate countries.

However the latches don't resist acids or chlorids, such as seaside environments.

There are several testing and manufacturing controls:

- BS: resistance to salt pray 72h to red rust

- White rust: decompostion of sacrifical zinc

- Red rust: Attack of the base material of the piece

- Traction tests: control of forces by traction bench

- Hardness testing: Control by a durometer

- Dimensional checks: Controls by a profile projector, digital callipers, digital trusquins, pins, thickness wedges

- Surface protection thickness control: Digital induction devices
