ASTM International Detention Test Standard

Over time customers requested a more tangible method of determining the suitability of detention locks for specific situations. The ASTM series of tests were developed in the 1980s and today they are the only detention-specific test standards in the world.

Two examples of these standards are:

Within the test standards there are four grade levels that locks can achieve (Grade 1 being the highest), which can further assist in determining the suitability of locks to the security level designation required by a facility.

This leads to some locks having dual designations listed in our catalogues, as the testing of all our locking products are the same regardless of the cylinder type.

All Southern Folger Detention Locking devices have achieved Grade 1, the maximum possible standard.

The designations listed in our catalogues are our evaluation of the ability of the products to withstand the rigours probable in various security levels within a facility. When reviewing lock selection for our clients, we consider the following:
  • key / cylinder type required
  • lock function
  • range of products needed
  • master keying complexity
  • security levels needed
  • level of inmate supervision (direct or indirect)
  • maintenance and durability.

For example, when comparing 10120AM (Medium / Maximum Security Level) with 1051M (Maximum Security Level) and 10300M (Minimum / Medium Security Level) locks, all three locks are tested to the maximum Grade 1 of ASTM F1577. All are functionally the same, so the final selection of lock type required will come down to the facility operator’s preference for key type and complexity of master keying and the anticipated level of abuse.

For more than 25 years, Southern Folger Detention Equipment Co has been providing suggested security levels for its products according to ASTM testing criteria.

When choosing locking products for use in detention environments, Access Hardware recommends that the end user, architect or specifier, insists that any product being submitted for approval has been tested under ASTM criteria as this will ensure that product will be fit for purpose in a detention environment. From this point, the selection can be further refined based on the application and particular requirements of the facility.Contact a representative for more information.
