All you need to know about the standards for Controlled door closing devices. British Standards for door closers - BS EN 1154 Explained - A Locks Online review!
Controlled door closers can be used anywhere, not just on fire doors. Depending on where you want to put them, they are mainly used commercially for fire doors, ensuring safety and security are met and to prevent unauthorized use of the door. When shopping round for controlled door closers, you need to ensure they comply with the BS EN 1154: 1997 and that the standards are met. As with most British Standards, don’t be put off with higher prices, for good quality products.
During this article, I will be referring to one of our products as an example. I will be looking at the Geze TS-2000 Overhead Door Closer with CF252 Fire Approval, which you can see here: https://www.locksonline.com/buy/TS-1500-overhead-door-closer-7098.html . In this case I will also refer to a fire door. Firstly, you need to distinguish what you need your product for and if it is for fire door purposes, will there be any chance of a high panic situation. You will also need to ask yourself, will this just be used once in a while, or will it be fixed on a door that is frequently used via customers etc.
So let’s narrow this down into 2 examples. If you are looking to place a door closing device on a shop door, which is located on a busy high street, you will need to think about how many times that door is going to open and close, on a daily basis. You will need to make sure the category of use is high, and that the corrosion resistance if the shop door is going to be close to outside weather.
If you’re looking to fix a controlled door closer to a fire door, you will need to ensure you have a high fire grade and ensure that the door mass it can withstand is more than 60kg. This is in case you have a mass panic situation and pressure is applied to the door itself.
So now I’m going to explain to you what the different categories are according to the BS EN 1154 – 1997. These specifications must be followed while fitting a new controlled door release. The categories are in the industry, known as ‘digits’. There are 6 digits in all. They are:
2. Number of Test Cycles
3. Test Door Mass
4. Fire Behavior
6. Corrosion Resistance
Category of Use - For all internal and external doors for use by the public, and others, with little incentive to take care, i.e. where there is some chance of misuse of the door
Grade 3: For closing doors from at least 105° open –
Grade 4: For closing doors from 180° open
- Note 1: Grade 4 classification assumes standard installation according to the manufacturer’s instructions.
- Note 2: For applications subject to extremes of abuse, or for particular limitations of opening angle, door closers incorporating a back check function or provision of a separate door stop should be considered.
Number of Test - cycles Only one test duration is identified for door closers manufactured to this standard:
Grade 8: 500 000 test cycles
Test door mass/size - 7 Grades Identified. Where a door closer provides a range of power sizes both the minimum and the maximum sizes shall be identified.
Fire behaviour- 2 Grades Identified
Grade 0: Not suitable for use on fire/smoke door assemblies –
Grade 1: Suitable for use on fire/smoke door assemblies, subject to satisfactory assessment of the contribution of the door closer to the fire resistance of specified fire/smoke assemblies. Such assessment is outside the scope of this European Standard.
Safety - All door closers are required to satisfy the Essential Requirement of safety in use. Therefore only grade 1 is identified.
Corrosion Resistance - 5 Grades Identified.
Grade 0: No defined corrosion resistance
Grade 1: Mild resistance
Grade 2: Moderate resistance
Grade 3: High resistance
Grade 4: Very high resistance
Here is an example of a controlled door we have on our website. Have a quick look at the link so you can see what I am explaining: https://www.locksonline.com/buy/TS-1500-overhead-door-closer-7098.html
As you can see by the table of boxes and numbers, this particular controlled door closer is good for: Closing doors from 180 degrees open / Has withstand 500,000 test cycles / can hold 60 to 80 kg / is suitable for use on fire doors / meets the required safety specifications / has a very high resistance to corrosion. I have worked this out from using the numbers in the boxes (the bold numbers under the symbols) and corresponding them with the correct category.
So as described above you will see how important it is to check out the classifications for the BS EN 1154 – 1997 Standard. Make sure when you’re looking for a new door closer, you read the specifications carefully as to suit your door. Whether you’re using one commercially or for domestic use, be careful how you choose your door closer.
