Fire Door Safety Week 2026: A Duty Holder’s Checklist for Industrial Fire Shutters and Lithium-Ion Battery Risks
7 September 2026
LPS 1175 is a Loss Prevention Standard published by LPCB (the Loss Prevention Certification Board), which is part of BRE Global, that specifies the requirements and testing procedures for certifying and listing the intruder resistance of various building components, security enclosures, and free-standing barriers. It aims to define a performance classification system that assesses a product’s ability to resist forced entry using different tool kits and time delays, and provides a framework for evaluating the physical security of such items. HAG Ltd. offers several product ranges tested to LPS 1175, including our Insurance Certified Steel Doors , Insurance Certified Roller Shutters and Insurance Certified Industrial Roller Shutters.
The standard uses a two-element classification system. The first element is a letter (A to H) representing the “Threat Level,” corresponding to the tool kit used and the number of attackers involved in the testing. The second element is a number (1, 3, 5, 10, 15, or 20) indicating the minimum delay (in minutes) a product achieved during a forced entry test. For example, a rating of “D10” means the product withstood a forced entry attempt with tool category “D” tools for at least 10 minutes.
The standard applies to a wide range of physical security products, including but not limited to: access covers, doors, windows, security screens, fencing systems, gates, grilles, shutters, strongpoints, security enclosures, sheds, tool stores, and even temporary buildings. The standard assesses the resistance of these products as complete assemblies, including their hardware (locks, hinges, etc.) and installation methods.
The ‘optimum locked condition’ refers to when all locking mechanisms on the product are engaged, making it as secure as possible. The ‘partial locked condition’ involves a less secure state, such as where only automatic latches or deadbolts are engaged, but not all supplemental locking devices. The standard requires products to meet certain security ratings in both partial and optimum locked conditions to ensure consistent protection. Crucially a product must achieve at least a security rating of A1 in every partial locked condition.
Each tool category represents a different level of intruder attack, ranging from an opportunist attack using easily concealed tools to extreme attempts at forced entry using heavy-duty equipment. Tool category A involves simple tools like screwdrivers, pliers, and tape. As the category progresses from B to H, the complexity and power of the tools increase, encompassing items like bolt cutters, drills, axes, grinders, and even chainsaws and hydraulic rescue tools. Higher threat levels also allow for a greater weight and quantity of tools.
Testing involves a series of manual intervention attack tests using tools from the specified tool category. Operatives attempt to force entry through the product or remove it from its substrate. The working time (time spent actively attempting to breach) and total test time are recorded. The test is considered a failure if a specified test block can pass through the product (or into it) within the allotted time or if the product is removed from its mount. Multiple tests may be conducted. Products are tested in both optimal and partial locked conditions.
Yes, LPS 1175 evaluates the adequacy of the manufacturer’s installation method, assuming the substrate has equivalent or greater resistance. The standard also looks at how fixings and anchorage systems resist attack. The standard does not classify individual components, such as glass or locks. Instead, it tests the product as a complete assembly. While the testing does not classify individual components, there are other LPS standards for testing components. Components such as lock cylinders accessible from the attack side of the product will need to comply with specifications laid out by other standards like BS3621 and LPS1242.
A ‘+’ suffix may be appended to the security rating. If a product has this rating, it means that the cylinders fitted to the product resist the manipulation methods defined within either Annex A of BS 3621:2017 or LPS 1242: Issue 2, meaning it has passed requirements for cylinder manipulation resistance. This indicates an additional level of security against lock picking or similar attacks.
