This standard was created by LPCB and offers levels of resistance/protection when referring to intruder resistant building components, strongpoints, security enclosures and free standing barriers.
Previously the LPS 1175 classifications were represented by a single digit. Now however the revision LPS 1175: Issue 8.0 has allowed for the extension of the standard, formed of two elements that classify performance. Performance is measured in terms of;
Threat Level - represented by a Letter, A to H, corresponding with a tool kit used to evaluate the product's intruder resistance. It also notes the number of attackers
Delay - represented by a numeric value. This value corresponds with a minimum delay (in minutes) provided by the product when placed in a locked condition.
Please refer to the table below that outlines differences between LPS 1175 Issue 7 and the revised Issue 8.
Not only are the products themselves tested but any hardware used within the product, i.e. a door leaf will not only be tested but the hinges, the lock and if it has a vision panel, the glass. These elements are tested to their corresponding standards, i.e. the glazing is tested to LPS 1270. As a door is an opening product with a frame the frame will also be tested, tested both as a combination, but it is also subject to a separate evaluation.
When a company wishes to have a product tested they will supply an agreed number of specimens. All test subjects will be complete with any hardware required, supplied and fitted. Additional pieces of hardware are supplied so they can be tested against their corresponding standard. The products are then installed by the manufacturer or their nominated installers. This is so the test is carried out in accurate conditions.
The overall objective is to confirm the security rating of the product and/or system This is achieved by carrying out a series of attack tests. This will then identify the minimum resistance to attack the product can provide.
These tests are carried out using different tool categories, dependant on the level of resistance/protection. For a better understanding, please refer to the Tool Categories page.
The security rating is determined in the minimum and optimum locked conditions using tools selected from the categories. In order for the product to achieve an LPS 1175 rating it must achieve the lowest security rating i.e. the number 1, in both locked conditions.
With each individual attack carried out a new tool kit may be selected. The attack tests continue until either the objective is achieved, the working time exceeds the defined duration, the total test duration exceeds the maximum time or the assessors decide the attack is ineffective for classification.
