BS EN 1527 – The right sliding door hardware for you, is the hardware standards for sliding and folding doors explained for the everyday person.
This British Standard covers most types of sliding and folding door hardware applications, with tests such as durability, fire resistance and corrosion resistance. Read on to find out if your sliding or folding door system has the correct door furniture for your insurance purposes.
When shopping around for your new sliding or folding door system, it is important to ensure you follow the correct procedures when it comes to insurance purposes! The last thing you need to do is to fit a new door system, only for it to fail on security and safety requirements. The BS EN 1527 covers the following door systems:
- Multi panel folding doors
- Bi folding doors
- Top hung straight sliding
- Bottom rolling (panels over 100kg)
The BS EN 1527 however does not cover door systems that are bottom rolling but weigh less than 100kg. There are also limitations to bespoke folding door systems so it is always a must to check that the hardware you are getting is tested for the right reasons.

You’re probably thinking ‘why is it so important to have door furniture tested for safety and security reasons?’ What happens if you have a fire in your home but need the sliding door system to hold off fire as a means of escape? Or, what happens if you have a straight sliding door system for outside use? Any indoor furniture will simply corrode, leaving you having to purchase more door furniture on a regular basis. The BS EN 1527 standard uses a 9 digit coding system, as does most British standards across the Ironmongery industry. You find these for items such as door handles and hinges. Again, once explained, it is very easy to follow! Most places will not show the code bar for items unless you ask for them so do not be afraid to get in touch with your supplier for more information!
Breaking down the classifications.
In each individual classification (the 9 digit code bar) there are numbers known as digits. These digits are each corresponded to a certain level of each feature in the standards performance requirements. It is now said that the DHF (Door and Hardware Federation) has specified using small images or icons in each box to make it easier for people to remember what to look out for. In each box there are 4 elements to look out for. Range/Options – Grade/Type – Symbol – Box. You can see this in the image provided.
For each digit, there are grades. These can range from 0 – 100. Depending on how many different variations are in the classification digits themselves. I am now going to explain the grades in each digit.
Digit 1 - Category of use
No grades identified for these products
Digit 2 - Durability – 6 Grades Identified
Durability is measured by the number is cycles performed under the test conditions. (How many times the door will open and close) No adjustment is allowed to any component during the testing stage. All components must stay serviceable throughout the test. During this test, all fittings must pass the initial friction test (digit 9 below) both before and after the durability test is performed.
Grade 1 – 2500 cycles
Grade 2 – 5000 cycles
Grade 3 – 10,000 cycles
Grade 4 – 25,000 cycles
Grade 5 – 50,000 cycles
Grade 6 – 100,000 cycles
Grade 1 – up to 50kg
Grade 2 – 51kg – 100kg
Grade 3 – 101kg to 330kg
Grade 4 – 330kg and over
Digit 4 – Fire Resistance – 2 Grades Identified
Grade 0 – Not approved to be used on fire doors
Grade 1 – Suitable to be used for smoke and fire resistant door assemblies, providing the door assembly has been assessed and is satisfactory to the EN 1634-1 Standard.
Digit 5 – Safety – No Requirements
Digit 6 – Corrosion Resistance – 5 Grades Identified in accordance with BS EN 1670
Grade 0 – No defined corrosion resistance
Grade 1 – Low resistance
Grade 2 – Moderate resistance
Grade 3 – High resistance
Grade 4 – Very high resistance
Digit 6 – Security – No requirements
Digit 8 – Category of door – 3 Grades Identified
Grade 1 – Straight sliding door
Grade 2 – Sliding / folding door
Grade 3 – Multi panel folding door
Digit 9 – Initial Friction – 3 Grades Identified
This digit measures how much force is applied to the door in order to start moving it. The grade allocated is variable depending on the weight of each door.
Here is an example:
As you can see in the image below, the following hardware is suitable for:
Use for commercial or domestic, doors that have been tested up to 2500 test cycles, suitable for doors up to 50kg, are suitable for fire resistant doors, has no safety requirements, has no defined corrosion resistance (not to be used outside!) has no security requirements, are for use on straight sliding doors, and has an initial friction equal to or less than 50 N.
Please note that hangers manufactured to this BS EN 1527 Standard needs to be marked with the manufactures name an or trade mark and some product identification. The identification should be shown on the product itself if possible, if not it must be shown on the packaging.
