All Lockwood product carry a Security Rating and Corrosion Resistance Rating to enable customers to select the padlock and accessory of an identical rating to maximise the performance of the padlock.
When selecting a padlock and accessory, always consider:
AUSTRALIAN STANDARD - AS 4145.4 2002 - Part 4: PADLOCKS
The Australian Standard AS 4145.4 enables the true evaluation of the physical security and corrosion resistance of padlocks and padlock accessories (excluding chains). The standard specifies performance requirements and describes test methods for strength, security, function and corrosion. Requirements that relate to security are classified in ten grades, based on performance tests that simulate attack. The security rating is based on the lowest test result achieved.
Test methods are specified in detail to ensure reproduction and consistency of assessment.
Chains not covered in the standard have been tested using the same test requirements and carry the appropriate Lockwood security rating.
Ten physical security grades are employed for padlocks. These grades are defined in part by the effective differs and key combinations.
For more detailed information please refer to Australian Standards AS4145.1, AS4145.2 and AS4145.4
10 grades of Keying security are available. K5 is only acceptable for grades SP8 - SP10 if the padlock body or other means prevents the drilling of the cylinder.
* For example, K6 keying security can have either key Control Level 2 or key Control Level 3
Note: K5 is only acceptable for grades SP8 - SP10 if the padlock body or other means prevents the drilling of the cylinder.
Three durability grades are employed for padlocks. The 10 physical security grades are also defined in-part by durability performance.
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
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.
