Security and Fire Door Ratings Explained
If you’re looking to invest in fire or security rated doors or grilles for your business premises, it’s important that you’re aware of the relevant industry standards so you may purchase the equipment that best suits your needs. This will ensure you’re not overpaying for an unnecessary level of security, and you will be able to keep your staff safe and assets secure at all times.
To help make sense of the relevant ratings and standards so you can get the ideal security or fire equipment for your needs, we’ve put together this helpful guide. Read on to find out everything you need to know.
Loss Prevention Certification Board Loss Prevention Standard 1175 (LPCB LPS 1175)
If you’re buying security doors, windows, or grilles, you should make sure that they meet the LPCB standard required to guarantee the safety of your staff. LPCB standards indicate the security level of external security equipment. If you store valuable assets or confidential information on your business premises, then investing in LPCB certified security equipment will go a long way to ensuring their safety, as well as that of your employees and any visitors to your site.
The LPCB’s Loss Prevention Standards (LPS) 1175 certification is heralded as the security standard of choice for the protection of government-associated national infrastructure in the UK, as well as being well recognised in the Middle East as a more stringent alternative to European standards. LPS testing has been formulated by the LPCB with input from the UK government, insurers, and police forces. Invest in a security door or window grille that meets these standards and your business premises will receive a guaranteed level of protection.
Intruder-resistant products are categorised under LPS 1175, which has 8 different ratings. The higher the rating, the more protection the piece of security equipment will provide. To get the ideal solution to your business’s security requirements, make sure you consider the threats your business premises is likely to face and choose the equipment that suits your particular needs.
To help you understand the certification and get the right security equipment for your business’s requirements, here’s a breakdown of the LPCB LPS 1175 security ratings (SR).
|Security rating classification||Tool category||Minimum test time||Minimum test duration|
|Tool category||Tools included|
|B||Tool category A plus:
|C||Tool category A and B plus:
* Complete with a spare power pack.
|D||Tool category A, B and C plus:
* Complete with one spare power pack.
|D+||Tool category A, B and C plus:
* Complete with one spare power pack.
|E||Tool category A, B, C and D+ plus:
|F||Tool category A, B, C, D+ and E plus:
*Measured at standard ambient temperature and pressure, purity <99.0%.
|G||Tool category A, B, C, D+, E and F plus:
*Measured at standard ambient temperature and pressure, purity <99.0%.
LPS 1175 SR1 & SR2
SR1 is the lowest level of security recognised by the LPCB. To meet this standard, products must be able to withstand opportunistic attempts at forced entry using minimal tools. The tester can use tools listed under tool category A in the LPS 1175 testing manual — which includes hand-held items such as spanners, knives, and screwdrivers — to attempt to force entry for a total attack time of up to a minute, over a period of 5 minutes.
SR2 testing simulates a more determined opportunistic attack. To reach this standard, a piece of security equipment must withstand a 3-minute attack from an assailant equipped with items from tool category B in the LPS 1175 testing manual — this includes claw hammers, hand drills, and junior hacksaws.
SR1 and SR2 certified security equipment is ideal for any business that stores items totalling a few thousand pounds, and is located in a densely populated area where someone is likely to be alerted to the sound of an opportunistic thief attempting to gain entry to the property. This makes it a great option for office buildings and small shops.
If this level of security sounds ideal for your business, take a look at our M2M1 security doors and CX2 security grilles for SR1 protection. Our M2M2 security doors, Extendor Vulcan grilles and cages, and Spartan2 bar sets are all certified to LPS 1175 SR2.
LPS 1175 SR3
In order to pass the stringent SR3 testing procedures, a door or grille must be able to endure an attack lasting 5 minutes, from an assailant armed with the typical equipment a thief who’s specifically targeted your premises may come equipped with. This includes larger hand tools, such as crowbars, hacksaws, and hammers, as well as items such as cordless drills and gas torches.
If your business is liable to be targeted by thieves, SR3 certified external security features will go a long way to ensuring that any attempts to enter your property are thwarted. If this sounds like the right level of protection for your business, take a look at our M2M3 security doors, SR3 Extendor Eclipse grilles and cages, and Spartan3 bar sets.
LPS 1175 SR4 & SR5
Items certified to SR4 and SR5 can resist attempts at forced entry from an experienced assailant for a duration of 10 minutes. During the SR4 test, the engineer attempting to breach the equipment has access to tool category D, which represents the kinds of equipment an experienced and prepared thief is likely to use. This includes cordless disc grinders, drills, and jigsaws, alongside manual tools such as sledgehammers and plate sheers. SR5 also includes the tools from tool category D+, which includes items such as a circular and reciprocating saws, and a cordless disc grinder.
To protect your business from all but the most intense of attacks, invest in our M2M4 security doors. These have never been breached, are often used for the protection of critical national infrastructure, government buildings, and other high risk establishments. They offer protection for premises that require all but the most intense physical security options.
LPS 1175 SR6, SR7 & SR8
Products rated SR6, SR7 or SR8 offer the ultimate protection against would-be intruders. The tests include repeated entry attempts made using a range of mains-powered tools in order to replicate professional attempts at entry from highly qualified assailants. These tools include circular saws, disc grinders, and drills.
To pass SR6, the equipment needs to endure 10 minutes of attack from an assailant armed with weapons from tool category E, which includes 1,100W circular saws and disc grinders amongst other mains-powered tools. The SR7 test also includes 10 minutes of assault over a 30-minute test period, but the tester has access to equipment from tool category F. This includes mains-powered saws and grinders exceeding 2,000W and an oxyacetylene “Saffire Portapak” cutting kit.
To pass the highest rating, SR8, a piece of security equipment must withstand twenty minutes of assault from an expert equipped with items from tool category G, which includes concrete chainsaws, hydraulic jacks, pneumatic impact tools, and 2000W drills fitted with diamond-core drill bits.
It should be noted that no manufacturer is yet to develop a product that meets the testing criteria for SR7 or SR8, and these standards exist primarily as something for engineers to aim for. For example, the Ministry of Defence is satisfied with the security offered by SR4, and it’s very rare that manufacturers get a request for anything higher than this.
Warrington Certification Certifire Rating
In order to ensure the safety of your employees, it’s important to invest in fire resistant equipment. This is especially the case if you own a factory or warehouse that houses machinery, as your premises is more likely to suffer a fire. Fire-rated doors are essential for emergency escape doors in industrial environments, commercial premises, offices, and schools.
Certifire is an independent, third-party certification that is recognised as the mark of fire safety across the UK. The government recommends that companies invest in third-party accredited fire safety materials in their Approved Fire Safety Document B for maximum safety, and a product with a Certifire mark guarantees that it will hold its integrity for the noted amount of time in the event of a fire.
In order to earn a Certifire rating, fire doors are subjected to a furnace test in which they have to endure temperatures of up to 1,100°C for the designated time. The test ends when the doors are compromised and smoke begins to leak from them, or after 240 minutes, the maximum Certifire rating.
The Certifire rating of a door is represented by FD and then a number (30, 60, 120, or 240). This number represents the total number of minutes a door maintains its structural integrity in the event of a fire.
To ensure the safety of your staff, invest in fire doors with a Certifire rating. The level your premises requires depends on how likely it is to suffer a substantial fire. If your business operates from a standard office block full of work equipment that does not pose an obvious fire threat, such as computers and standard office equipment, the lowest rated fire door should provide the sufficient level of protection.
However, if you’re investing in the fireproof equipment for a warehouse or factory where industrial machinery and handling equipment is often used, a fire is more likely, and a door with a higher rating will be necessary. This is also true of buildings that contain invaluable items or documents, such as banks and government buildings.
You should keep in mind how long it takes your business premises to be completely evacuated when investing in a fireproof door, as you will require one that will maintain its structural integrity until the building has been emptied. You should be aware of how long this takes from your fire drill records, and you should invest in a door that will stay intact for the length of the evacuation. The larger your business premises, the higher FD rating you’ll require when buying your fireproof doors.
If you’re looking for fire doors for your business, then take a look at our range of fire rated doors, which are Certifire accredited up to FD240. All of Bradbury’s LPS 1175 rated doors are also available with optional Certifire rating, making them the perfect choice if you want to protect your staff from fire hazards as well as external physical threats.
