A small insight on door furniture standards. A quick guide on British Standards for Door Furniture - BS EN 1906 Explained!
If you’re thinking of buying door furniture for your home or office, you need to ensure your getting the best quality. Below is a small guide on what standards you need for door furniture, and what effect it will have on your overall outcome. Written for the everyday person who isn't involved in the industry, I have broken down the main points of the BS EN 1906 and what you need to look for.
So what is a British Standard?
A British Standard (BS) is something which is set up to ensure goods, services or products comply with health and safety rules and certain qualities that the goods hold. Everything that is manufactured and sold will need to have some sort of guide that they have to comply with to ensure they are safe to use. So what is the BS EN 1906? It’s simply a standard, for door furniture.
The BS EN 1906 only complies with door furniture such as lever handles and door knobs which have a backplate or a rose. They only correspond if the lever handle or knob operates with a lock or a latch. This BS is broken down into categories such as Fire resistance, Durability and Safety. These are also known as test methods. The BS EN 1906 has a grade scheme of 1 to 8 in each category, and each grade refers to a particular feature or product which is measured against the performance of the standards requirements.
What are the different feature categories for BS EN 1906?
There are 8 categories in all for this standard, also known as ‘Digits’. They are:
1. Category of Use
3. Test Door Mass
4. Fire Resistance
6. Corrosion Resistance
8. Type of operation
Category of Use – 4 Grades Identified
Grade 1: Medium frequency of use with a high incentive to exercise care and a small chance of misuse, e.g. internal residential doors
Grade 2: Medium frequency of use by people with some incentive to exercise care but where there is some chance of misuse, e.g. internal office doors
Grade 3: High frequency of use by public or others with little incentive to exercise care and with a high chance of misuse, e.g. public office doors
Grade 4: High frequency of use on doors which are subject to frequent violent use, e.g. football stadiums, oil rigs, barracks, public toilets, etc.
Durability – 2 Grades Identified
Grade 6: Medium use - 100 000 cycles
Grade 7: High use - 200 000 cycles
The tests undertaken to achieve these grades involve the application of additional forces to the door furniture in order to simulate the conditions of use likely to be experienced in the field.
Test Door Mass
Fire Resistance – 2 Grades Identified
Grade 0: not approved for use on fire/smoke door assemblies.
Grade 1: suitable for use on fire/smoke door assemblies.
Note: A Grade 1 classification means only that the furniture has been designed for use on fire/smoke control doors; the actual fire performance achieved (e.g. fire integrity of 30 minutes on a partially glazed timber door etc.) will be contained in a separate fire test report.
Safety – 2 Grades Identified
Grade 0: Normal use
Grade 1: Safety application - to qualify for this grade, handles must have high strength handle-to-plate and plate-to-door fixing and/or handle-to-spindle fixing, such that they would withstand a person grabbing in order to prevent falling. It is recommended that only Safety Grade 1 furniture is used at the top of cellar steps or other staircases.
Corrosion Resistance – 5 Grades identified
Grade 0: No defined corrosion resistance.
Grade1: Mild resistance - minimum requirement for internal use.
Grade 2: Moderate resistance.
Grade 3: High resistance - minimum requirement for external use.
Grade 4: very high resistance - recommended for use in exposed marine atmospheres or very polluted industrial environments.
Note: Products intended to develop a natural patina (such as bronze or brass) are not required to comply with any requirements.
Security – 4 Grades Identified
Grade 0: Not approved for use on burglary resistant doors.
Grade 1: Mild burglary resistance.
Grade 2: Moderate burglary resistance.
Grade 3: High burglary resistance.
Grade 4: Extra high burglary resistance Note: The main requirements include resistance to drilling, close fitting plates or escutcheons to help protect the lock and support the cylinder. They must be resistant to removal from the outside of the door and make provision to minimise the cylinder projection to a maximum of 3mm. Full details of the requirements can be found in BS EN 1906.
Type of Operation – 3 Operations Identified
Type A: Spring assisted furniture.
Type B: Spring loaded furniture.
Type U: Unsprung furniture.
Here is an example of one of our door handles we have on our site. You cal see the product here, so you can get a feel of what I am explaining: https://www.locksonline.com/buy/FSB-1029-lever-handles-2185.html
The classification for this particular handle is shown in the picture of boxes below.
This handle is good for: High frequency use on doors/ has withstand 200,000 test cycles / Test door mass has no requirements / Is suitable for use on fire doors / is good for a use of safety / has a high resistance to corrosion / has not been approved for burglary resistant doors / is Unsprung. To get these I corresponded the numbers in the bottom boxes of the chart with the correct digit above. This is how you can tell what the specifications are, and whether it is suitable for your purpose.
So as you can see there are many variations for many different types of door handles or knobs. The decision lies on what type of door furniture you need, whether it is for indoor or outdoor use, commercial or domestic use or purely just something fancy. Either way, when looking for door furniture always check the BS to check whether the goods are right for you and your environment. Don’t be afraid to spend a little more for a better quality if you will be using the handles or knobs for more of a commercial use such as office or shop. Make sure you check the BS and way up the pros and cons for whatever door furniture you are buying to ensure you the best quality product suited for you needs.
