LPCB logoThe Loss Prevention Certification Board (LPCB) offers third-party testing of products, confirming that products meet a certain criteria, and providing a certified standard of security.

LPS 1175 evaluates the resistance to unauthorised access offered by various physical security products.

The standard specifies eight grades of Security Rating according to the tools and time likely to be used by a criminal.

SR1 testing replicates an opportunistic attack using physical bodily force and by stealth, using minimal tools. SR2 testing simultates a more determined opportunistic attack using physical bodily force and tools with a higher mechanical advantage. SR3 testing replicates a deliberate forced entry of well-protected premises using physical bodily force and a wide selection of attack options. SR4 testing simulates experienced attempts of forced entry.

Bradbury supplies a wide range of LPCB certified products, including security doors, retractable grilles, cages and bar sets. Our M2M1, M2M2, M2M3, and M2M4 doors are certified to SR1, SR2, SR3, and SR4, respectively. Bradbury CX2 grilles are certified to SR1, and our Extendor Vulcan grilles are certified to SR2. We also manufacture the only grille to achieve SR3 certification, the Extendor Eclipse. Bradbury's Spartan bar sets and Extendor cages are available with SR2 and SR3 certification.

LPS 1214 is the specification for testing and classifying physical protection devices for personal computers and similar equipment. The standard confirms the security category expectation of a protection device by conducting a series of manual intervention tests. LPS 1214 specifies two grades of security; Security Category 1, and Security Category 2.

SC1 certification is awarded if it is not possible to remove the equipment from its secured position, and the protection devide must resist physical attack for a total working time of 3 minutes. SC2 certification is awarded if it is not possible to open the door, deform the door, or penetrate the body to provide an access area, and the requirements of SC1 are met.

The tools used to attack the protection devices during these tests, include a knife, claw-hammer, hand drill, drill bit, junior hacksaw, pipe wrench and screwdrivers.

Subsidiary of the Bradbury Group, Cross-guard, manufactures Ventis Server Safes which are certified to SC2, making them the strongest self ventilating server safe on the market.

certifire logoCERTIFIRE is an independent third party Warrington Certification scheme that assures performance, quality, reliability and traceability of fire protection products. 

Bradbury's M2MFD range of fire rated doors have been CERTIFIRE accredited to FD240 (as defined by EN16341:2008 or BS476:Part 22:1987). To achieve certification, the doors were subjected to a furnace test, withstanding temperatures of up to 1100oC for a period in excess of four hours.

As well as manufacturing standard M2M+FD doors, Bradbury is one of few manufacturers to offer doors with both CERTIFIRE and LPCB certification. Our M2M1FD, M2M2FD, M2M3FD and M2M4FD doors are certified to LPS 1175 SR1, SR2, SR3 and SR4, respectively.

CE markingCE Marking on a product is a manufacturer's declaration that the product complies with the essential requirements of the relevant European legislation, and indicates to governmental officials that the product may be legally placed on the market in their country. 

CE Marking on a product ensures the free movement of the product within the EFTA & European Union (EU) single market (total 28 countries), and permits the withdrawal of the non-conforming products by customs and enforcement/vigilance authorities.

In line with European legislation, all Bradbury Security doors (excluding fire rated doors) carry a CE Marking.
