If you are confused about security door standards such as STS202 BR1, BR2, BR3 and BR4 then read on, we’ll try to explain!
STS202 explained
The technical specification STS202 (also known as STS202 Issue 3: 2011) involves a series of stringent tests. These tests are graded into separate classes of resistance. Each one of these classes equates to an increasingly prolonged attack and an additional set of available tools for the ‘attacker’. The testing is timed, and the goal is to see if the intruder can create an opening (large enough to gain access) within a certain period of time, which for a BR2 Product is 15 minutes of actual attack time. The BR standard focus’ highly on real life parameters.
What are STS202 BR1 and BR2?
These are separate attack levels that a door has to withstand to be able to be credited this standard. While it is associated with opportunist break-ins, it is still surprising how many doors currently sold in the UK fail this test. Typical attacks in this category are likely to avoid unnecessary risk and noise such as heavy banging or power tool usage. The tools used are commonly hand tools, levers and physical force.
What are STS202 BR3 and BR4?
These are more stringent attack levels that you would definitely associate with more experienced burglars who are aware of their likely reward. These criminals plan their attacks well and are prepared to make noise to get through the door. The attack tools used range include:
- spanners
- lock picking tools
- screwdrivers
- pliers
- wedges
- mole grips
- large hammers
- battery powered drills
- cold chisels
- bolt cutters
- axes
- large crowbars
- forceful kicks and blows
Where would you find BR3 and BR4 doors?
These are often found on more commercial properties as can they withstand attacks for a longer duration.
What is RC2 (Resistance Class 2)
RC2 comes from the European standard EN 1627. It’s used across Europe to test security products like doors, windows, shutters, and grilles. RC2 is also focused on protection from casual thieves. The test assumes the attacker is using simple tools like a screwdriver, small hammer, and pliers. However, RC2 is more standardized across Europe and includes detailed requirements for how the testing must be carried out. The test also assumes the intruder has some knowledge of the product and spends up to 3 minutes actively trying to break in. RC2 focuses less on real life situations and more on a standard of testing.
What is LPS 1175 SR2 (Security Rating 2)
LPS 1175 is a standard from the Loss Prevention Certification Board (LPCB) in the UK. SR2 is often used in places like utility sites, government buildings, or data centres. These are places where break-ins could be extremely serious. For most homes and small businesses, it’s more than you need.
SR2 products are generally more suited towards commercial sites rather than discreet security for residential homes.
