C | Corrosion Resistance

 

All Lockwood padlocks and padlock accessories are exposed to an accelerated corrosion test to evaluate their resistance to corrosion. Exposure is to a neutral salt spray in accordance with related Australian standards. Padlocks and padlock accessories are classified in five grades as listed below

CATEGORY EXPOSURE ENVIRONMENT
C1- Very Low Not applicable.
C2 - Low Environments that are normally dry, including the majority of interiors
C3 - Moderate Environments that are sometimes damp in the majority of rural and suburban localites, including interiors where condensation may occur
C4 - High Environments that are often wet and/or subject to slight pollution by sulpher dioxide, acid, alkali or salt, including some particularly damp interiors and the majority of exterior environments.
C5 - Very High Environments in very corrosive localities such as those subject to effect (or combination) of industrial and coastal conditions.

The padlocks and padlock accessories are exposed to the neutral salt spray for up to 240 hours (Grade 5). After the test it must be possible to operate the padlock with its key in the normal manner.

For more detailed information please refer to Australian Standards AS4145.1, AS4145.2 and AS4145.4
