LPS 1175 ISSUE 8 Security Ratings Explained

Teckentrup Lps1175 Issue8 Standard Explained Header

LPS 1175 ISSUE 8... what does it mean in terms of security?

Steel security rated doors are designed to withstand physical attack for varying periods of time, with a variety of attack tools. The longer the attack time, and the more aggressive the tools used, the higher the doors’ performance rating.

Without certified test evidence of performance, any claims for a doors’ security are unproven.

Teckentrup 62 doors have been tested to all the widely recognised standards including the new LPS 1175 issue 8. The bracketed rating, e.g. (SR1) provides the equivalent under Issue 7 where applicable.

The commonly required security levels, along with the typical applications are shown below. The standard has more extended times and tool kits, however as, apart from highly specialised applications, LPS 1175 D10 (SR4) is generally the highest requirement and we’ve limited the listing up to this level.


Under the new LPS1175 Issue 8 standard, Teckentrup 62 provides the following range:

  • Teckentrup 62 Secure 1 LPS 1175 A1 (SR1)
    Tool type A, 1 minute attack, max test duration 10 minutes
    Opportunist attack using small, easily concealed tools, typically used for domestic and low commercial risks.
  • Teckentrup 62 Secure 2 LPS 1175 B3 (SR2) 
    Tool type B, 3 minute attack, max test duration 15 minutes
    More determined opportunist attack using tools of greater mechanical advantage, typically used for domestic and low commercial risks such as office buildings, schools and small shops.
  • Teckentrup 62 Secure 3 LPS 1175 C5 (SR3) 
    Tool type C, 5 minute attack, max test duration 20 minutes
    Deliberate forced entry using a wide selection of commonly available tools, typically used for higher commercial risks and infrastructure. 
  • Teckentrup 62 Secure 3+ LPS 1175 D5 
    Tool type D, 5 minute attack, max test duration 20 minutes
    Experienced attempts at forced entry, typically used for higher commercial risks and infrastructure.
  • Teckentrup 62 Secure 4 LPS 1175 D10 (SR4)
    Tool type D, 10 minute attack, max test duration 30 minutes
    Experienced attempts at forced entry, typically used for high commercial risks and critical infrastructure. 

What about stealth?

  • LPS 2081 “stealth”
    The test categorises opportunist attack using stealth and small, easily concealed tools (Type A) or tools with greater mechanical advantage, fairly easy to conceal about the person (Type B). Typically used for domestic and low commercial risks.
    Teckentrup 62 Secure A LPS 2081 A 
    Tool type A, 1 minute attack, max test duration 10 minutes 
    Teckentrup 62 Secure B LPS 2081 B
    Tool type B, 3 minute attack, max test duration 15 minutes

What about ballistics?

  • BS EN 1522 FB4
    Armed attackers are also thwarted with Teckentrup 62 tested to FB4 resistance.
