What is LPS1175 & SR Rating?

LPS1175 Issue 8 Certificate Zaun

What is LPS 1175 and what is an SR Rating? LPS 1175 is the requirements and testing procedures for the LPCB approval. A listing of intruder resistant building components, strong points, security enclosures and also free-standing barriers, fencing and gates.

LPS 1175 covers the broadest scope of physical security products and services of any publicly available standard in the world. LPS 1175 is the result of many years of work by LPCB, UK Government, Insurers and also Police. It has rapidly become a core element of physical security specification across many sectors.

The standard comprises a number of security ratings with test requirements of ascending intensity. These are measured in terms of attack tools and also time available to the attacker. This enables specifiers to select products according to the risks that they and their property face.

LPS 1175 used in a range of applications, from residential right through to critical infrastructure projects.

Products provide resistance to extreme means of attempted forced entry into higher value areas.

What are the ratings?

Under Issue 7 – Security Ratings would be listed as follows

  • SR8 Rated Products – Provide high levels of resistance to professional means of attempted forced entry into higher value storage areas. Using a wide range of tools including mains powered tools.
  • SR6 & 7 Rated Products – Provide high levels of resistance to professional means of attempted forced entry into higher value storage areas. Using a wide range of tools including mains powered tools
  • SR4 & 5 Rated Products – Resist experienced attempts at forced entry using a wide range of tools including battery powered tools lasting up to 10 minutes depending on the security rating sought.
  • SR3 Rated Products – Provide moderate resistance to determined attempts of force entry using a range of techniques including those that involve creation of noise.
  • SR1 & SR2 Rated Products – Provide the minimum levels of recognised resistance to opportunist attempts at forced entry using a range of techniques including those that create noise such as those involving breaking glass.

Under Issue 8 the security ratings have now changed. The table below shows the Security Ratings and explains the resistance levels of ratings 1 to 4

Who Does the Testing?

LPCB (Loss Prevention Certification Board) do all of the testing for an SR Rating. They have been setting standards for loss prevention since the 1800’s. Its standards and approvals for security products are also recognised across the world.

That recognition is testimony to the extremely thorough technical evaluation work and rigorous quality audit processes undertaken by LPCB to ensure the security products it tests and approves also deliver proven levels of protection.

LPCB works closely with government, police, insurers, risk consultants and architects to develop standards and approval schemes which ensure security equipment and services deliver the levels of performance required to protect against criminal and terrorist threats.

Approval to LPCB’s Loss Prevention Standards (LPSs) is specified across multiple sectors, including: education, finance, healthcare, manufacturing, the public sector, residential, retail and also utilities. The standards are also specified for the protection of critical infrastructure where delivery of specified levels of security performance is critical.

All products approved by LPCB, entered into the RED BOOK.

What is the RED BOOK?

Once LPCB is satisfied that a product or service meets the required standard, it is listed in the ‘Red Book’. The Red Book, published in January each year and also available free of charge. A live version of the Red Book can be also be viewed free of charge on www.RedBookLive.com where new entries and amendments are updated constantly.
