FAQs - security, durability & weather testing

Frequently asked questions about security, durability and weather testing.

1. What tests are covered by Exova's mechanical testing division?
Exova provides testing to British, European and International standards for Secured by Design, CE marking and individual specifier requirements for doors and windows, including:

Security testing to
  • PAS 24 - Doorsets
  • BS 7950 - Windows
Weather performance testing to
  • BS 6375 Part 1
Operational and strength testing to
  • BS 6375 Part 2 and Part 3
  • PAS 23
  • DD171 and EN1192
  • HTM58 (NHS Estates: Internal Doors)
Client specific test programmes
  • Bespoke or new testing for products that are non-standard or new to market (e.g. the fit for purpose test program CDTM01)
  • European burglary resistance standards (prEN 1627, prEN 1628, prEN1629 and prEN1630)
2. What size and configuration of product is required for the test?
As guidance, the door or window should generally be of the largest size that the manufacturer wishes the test evidence to cover. A rule of thumb is that if all other details are identical a larger door or window will generally be more vulnerable than a smaller one. However this may not always be the case and so it is worth discussing with your certification body the range of products you require to be covered by the program. This will ensure the minimum amount of testing will be required to cover your product range(s).
3. Can I watch my product(s) being testing?
Yes and we encourage you to attend testing as a means of developing your understanding of the test and in the event of any failures or issues relating to the test to allow a fast and effective resolution of these issues.

Due to client confidentiality, we cannot allow witnessing of product tests other than your own without written consent from the testing manufacturer.
4. What is required for CE marking of doors and windows?
This is explained separately in the following CE marking for EN 14351 FAQs.
5. Can I use my supplier's test evidence for CE marking?
With CE marking, the cascade of test evidence is possible within the rules of CE marking. If you are using a profile supplier’s evidence, they must satisfy themselves that you the fabricator is producing fully to their requirements.
6) What is Secured By Design (SBD)?
Secured By Design is an initiative by the Association of Chief Police Officers Crime Prevention Initiatives (ACPO CPI Ltd) intended to reduce crime by ensuring the design and specification of the building is such that opportunist thieves are prevented from successfully breaking into homes. It is currently the biggest driver in the UK for security testing.
7. What is required by SBD?
Details of the full requirements of Secured By Design can be found in the SBD New Homes document on the SBD website.
8. How do I go about getting third party certification?
We can provide certification for enhanced security doors and windows and for enhanced lifetime performance of doors.

The certification process includes audits of the production systems and quality management of your doors and windows with respect to the requirements of Secured by Design.
9. Can I use my supplier’s test evidence for SBD?
For Exova BM TRADA certification it is possible to use a design of door and window that has been tested on behalf of another organisation or under a different company name at an accredited test laboratory assuming the fabricator has the relevant permission to use this test evidence and the product they are producing is using the same components.
10. Can I use European security test evidence for SBD?
No. The European burglary resistance standards prEN1627, prEN1628, prEN1629 and prEN1630 are draft documents awaiting publication and are not currently accepted by SBD. Other European test evidence such as weathertightness may be suitable if conducted to the required level and by a laboratory recognised by the certification body.
11. What are all these standards? What do they involve?
  • PAS 23-1 addresses the weathertightness, operational strength and durability of the doorset to demonstrate that it is generally fit for purpose. PAS 24 is the security test standard for doorsets evaluating the resistance to opportunist attack using both manual attacks using specific toolsets as well as mechanical simulations of a crowbar attack and impact of the leaf with hard and soft impactors.
  • BS 7950 is the security test standard for windows evaluating the resistance to opportunist attack using both manual attacks using specific toolsets as well as mechanical simulations of a crowbar attack.
  • BS 6375: Part 1 (test to EN 1026: 2000, EN 1027: 2000, and EN 12211: 2000), is the UK guidance document for the European test standards for weathertightness (air permeability, watertightness and wind loading) it is possible for these tests to be carried out anywhere in Europe. However a test result that may be acceptable in one country may not meet the requirements of BS 6375 Part 1.
  • BS 6375 Part 1 also includes guidance for the architect in relation to specifying the expected classification requirements for windows and doors in terms of these tests.
  • BS 6375: Part 2 is the UK guidance document for the European test standards for operational strength with reference to the test standards raised in EN 14351-1 product standard for CE marking. These tests are for windows cyclic testing to 10,000 operations, a racking load on the window and a twisting load on the open window.  All of these tests are measured against the forces needed to operate the window.
  • BS 6375: Part 3 addresses the characteristics of EN 14351 that are not included in the Part 1 or 2 documents and will not all be applicable to a product. The only test that is generally used from this is a basic security test called up in the material standards for windows.
