LPS 1175 Security Ratings Explained

This is the complete guide to what the LPS 1175 Security Ratings really are, why they are important, and what that means for you.

This is an extensive guide, so here are some quick links to the different sections:

First things first:

What is LPS 1175?

‘LPS’ stands for ‘Loss Prevention Standard’ and LPS 1175 is one of many LPS standards by the LPCB (Loss Prevention Certification Board).

The 1175 standard itself is focused on the physical security of ‘intruder resistant building components’, which includes strong-points, security enclosures, free-standing barriers, and any products that fall within those categories, such as doors and shutters.

This useful diagram from BRE shows the areas of asset protection that the LPS 1175 standard is relevant to, and the standards that cover all other areas of asset protection.

Simply put, physical security concerns four main areas: Deterring intruders, Detecting and Delaying attackers, and Responding to an attack.

how are lps 1175 security ratings measured?

The LPS 1175 Issue 7 standard uses different tool kits and different attack durations to categorise the security rating a product is certified to.

These ratings are split into 8 different security ratings (SR levels), each one intended to represent a different threat scenario.

As each rating goes up, both tool-kit and attack duration change.

The basis for this is that if an attacker is likely to use more serious tools in an attack, then they’ll also be more committed to the attack, so more will spend longer trying to defeat the product before abandoning.

lps 1175 issue 7 table

In the table above, Maximum attack time is how long the attacker can be physically attacking the product.

In the LPS 1175 test, attackers are allowed breaks between attacks, and so the total of the attack time and the breaks is not allowed to exceed the Maximum total attack duration.

E.g. at SR4 level, the attacker could have five sets of two minute attacks, with twenty minutes dispersed between them; giving a total attack duration of thirty minutes.

LPS 1175 Security Ratings Explained

LPS 1175 Security Ratings are the different categories the LPS 1175 standard uses to grade the resistance of a physical security product.

The ratings are from SR2 to SR8, and are designed to imitate different risk scenarios.

Below is an overview of each rating, including the attack time, attack duration and the attack tool specification.

SR1

Based upon low domestic risk and low commercial risk.

Products certified to this rating provide a level of resistance to opportunist attempts at forced entry, using bodily physical force and a limited range of hand tools, including those that create noise.

  • Tool Kit A
  • Maximum attack time: 1 minute
  • Maximum attack duration: 10 minutes.

SR2

Based upon medium domestic risk and lower commercial risk.

Products certified to this security rating provide resistance to opportunist attempts at forced entry, using bodily physical force and a range of hand tools, including those that create noise.

  • Tool Kit B
  • Maximum attack time: 3 minutes
  • Maximum attack duration: 15 minutes.

SR3

Based on a low commercial risk.

Products certified to this level of security provide a moderate resistance to determined attempts of force using a bodily force and a wide range of hand tools with greater mechanical advantage, including those that create noise.

  • Tool Kit C
  • Maximum attack time: 5 minutes
  • Maximum attack duration: 20 minutes.

SR4

Based on a medium commercial risk.

Products certified to this level provide resistance to experienced determined attempts at forced entry using a wide range of hand tools and battery power tools, with a disregard for noise created.

  • Tool Kit D
  • Maximum attack time: 10 minutes
  • Maximum attack duration: 30 minutes.

SR5

Based on a high commercial and mission critical risk.

Products certified to this security rating provide resistance to experienced determined attempts at forced entry for extended periods of time, using a range of powerful battery tools lasting up to 10 minutes.

  • Tool Kit D+
  • Maximum attack time: 10 minutes
  • Maximum attack duration: 30 minutes.

Download the full LPS 1175 SR5 test specification here:

SR6

Professional attempt at forced entry using highly specialist power tools.

  • Tool Kit E
  • Maximum attack time: 10 minutes
  • Maximum attack duration: 30 minutes.

SR7

A professional means of attempting forced entry into higher value storage areas generally after penetrating the facade.

  • Tool Kit F
  • Maximum attack time: 10 minutes
  • Maximum attack duration: 30 minutes.

SR8

Extreme means of attempting forced entry into higher value storage areas before resorting to the use of vehicles, firearms or explosives.

  • Tool Kit G
  • Maximum attack time: 20 minutes
  • Maximum attack duration: 60 minutes.

who writes the lps 1175 standard?

Although the LPS 1175 standard is written and controlled by the LPCB, this is done in close consultation with many other bodies.

Close dialogue with the Government, Insurers, the Police, Risk Consultants, Architects and other industry experts means that the standard remains as relevant as possible to the physical security market.

security professionals

The team of LPCB security experts draft the standard (and the subsequent revisions) and then it is reviewed and commented on by the other industry experts.

The two main bodies to be aware of here are BRE and LPCB:

BRE

At the top level of security certification is the BRE, or Building Research Establishment.

They’re an independent and impartial, research-based consultancy group, who offer testing and training in aspects of built environments.

Principally, they help the government and businesses make informed decisions on essential, construction-based purchases.

LPCB

So, what is LPCB?

Part of the BRE is the Loss Prevention Certification Board (LPCB).

This is a certification board specifically offering accreditation to security systems and products that meet strict standards and test requirements.

The LPCB are currently the leading centre for fire and security product testing and approvals internationally, with nearly 70 Loss Prevent Standards (LPS) currently in effect.

Each LPS is dedicated to ensuring one element of the property is secure, built up from the very basics of effective security to protecting property and people from terror attacks.

The LPS security standards are based on grading structures, developed over time on proven crime science.

The grading structures recognise the increased investment criminals and/or terrorists will make to reap the greater rewards.

Each Loss Prevention Standard covers an element of the property, as shown below:

How do I tell if a product has LPS 1175 Accreditation?

Every security product certified to LPS 1175 gets entered on to what is known as the RedBook Live.

redbook live

RedBook Live contains a live listing for every product certified by the LPCB to LPS 1175.

LPCB own and control the website, so as a specifier you can be 100% certain that any product listed on there meets the criteria.

In order to retain certification, manufacturers must undergo ongoing auditing to ensure that they have thorough and effective quality control procedures in place in their manufacturing processes.

This is another factor that contributes to LPCB’s popularity with specifiers and architects – not only does the mark guarantee a security resistance, it also guarantees an effective Quality Control process.

LPS 1175 Vs EN 1627

In researching security standards and ratings, you’re likely to have also come across EN 1627.

So what’s the difference between LPS 1175 and EN 1627?

EN 1627 (as the name suggests) is a European standard, and is structured on the same level based categorisation as LPS 1175, Issue 7.

EN 1627 ratings go from RC1 to RC6, and attack times and attack tools increase with the levels, just as they do in LPS 1175, Issue 7.

EN 1627 ratings table

So where do they differ?

The main difference is that EN 1627 is mainly aimed at protecting against criminals using stealth to gain access, rather than the higher levels of security covered by LPS 1175.

An example of this is that EN 1627 assumes that criminals won’t break panes of glass to gain access.

There are also some key differences in the tool kits used in the two standards: EN 1627 doesn’t include some common tools, such as claw hammers, 18V drills and reciprocating saws.

LPS 1175 also includes more powerful equipment such as petrol-driven grinders used by criminal gangs, which EN 1627 does not.

Although any independent standard is better than none, LPS 1175 is generally recognised as the more relevant standard in the security industry today, as it recognises more recent security trends and changes, such as the commonality of power tools.

LPS 1175 Vs PAS 24

PAS 24 is a British standard, and there are two main areas where it differs from the LPS 1175 standard:

PAS 24 is a ‘minimum standard’

What this means is that, unlike LPS 1775 Issue 7 with 9 different levels, a product either has PAS 24, or it doesn’t.

There’s no grading structure, it’s simply a pass or a fail.

The other difference is that (like EN 1627) PAS 24 is based more on a criminality threat in a residential environment.

This means that the attack test doesn’t allow the attacker to break panes of glass, for instance.

So although there are instances where PAS 24 is sufficient, LPS 1175 is generally regarded as the more thorough testing standard.

How do i know which lps 1175 security rating i need?

There are 5 main areas you need to consider when you’re assessing which LPS 1175 security rating is the most appropriate for you:

What are you protecting?

What is it that you’re looking to defend? Securing property requires a different approach to protecting people for example.

What is your area of business?

What sector does your application come under? The LPS 1175 standard applies to all sectors, but different applications will have different operational and aesthetic requirements as well as the need for security.

What threat are you protecting against?

At one level, a very obvious factor when looking at the LPS 1175 standard, but being clear as to the threat you are protecting against is not always as simple as it may at first appear.

Where is the property located?

Both geographical (what country / county is the property in) and locational (what is around the property) affect the security rating needed.

What is the likely attack frequency and severity?

How common is the threat you’re protecting against, and will it be opportunist, or professional?
