If you’re buying new building hardware goods, you need to make sure they comply with the BS EN 1935. Whether you’re looking for hinges for your window, door or furniture, you want to make sure you have a good quality product. I have pulled together some useful information regarding the standards of building hardware and what to look for while shopping for your goods. Don’t be put off with the volume of information regarding the BS EN 1935, once you read the ins and outs you will see how easy it is to navigate. This is the BS EN 1935 Explained!
First you need to distinguish what exactly you need your goods for. For example, I’m going to use hinges throughout this article so you all have something to refer to. Once you have identified what hinges you’re looking for you need to ask yourself, how much wear and tear will these hinges go through? So let’s narrow this down:
If you have a shop and you need new hinges for your door, you need to go for a good quality hinge that can withstand a potential 200 – 300 customers walking through your door. There is no use going for a budget hinge, as, as you can imagine, the door will just fall off.
If you are looking for a hinge for a door in your home such as the bedroom door, chances are you’re only going to use the door apx 6 times that day. Going for a budget hinge here will be fine as it will withstand light duty use.

Now, abit of health and safety for you! If you’re looking to get hinges for a fire door, you can’t just use standard or budget hinges. You need to check out the regulations you need to follow to ensure you’re following the relevant standards. BS EN 1935 states that a hinge fitted to fire – resisting doors should be able to achieve the intended fire rating and that the hinge should be able to allow the door closing device, when fitted to a fire-resisting door assembly, to close the door leaf reliably from any angle to which it has been opened, overcoming the resistance of a latch or any seals when fitted.

I’m going to now get into some detail about the different categories of the BS EN 1935. These categories are, in the industry, known as ‘Digits’. There are 8 digits in all and they are:
1. Category of duty
3. Test door mass
6. Corrosion resistance
8. Hinge grade
Category of Use – 4 Grades Identified
Grade 1: light duty
Grade 2: medium duty
Grade 3: heavy duty
Grade 4: severe duty
Durability - 3 Grades Identified for single-axis hinges manufactured to this European standard
Grade 3: 10 000 test cycles, for light duty hinges on windows only
Grade 4: 25 000 test cycles, for light duty hinges on windows and doors
Grade 7: 200 000 test cycles, for medium - heavy and severe duty hinges on doors only
Test Door Mass - 8 Grades related to single-axis hinges are identified in this European standard as shown in this table:
Suitability for Fire/Smoke Door Use - 2 Grades Identified
Grade 0: not suitable for fire/smoke resistant door assemblies
Grade 1: suitable for fire/smoke resistant door assemblies subject to satisfactory assessment of the contribution of the single-axis hinge to the fire resistance of the specified fire/smoke door assemblies. Such assessment is beyond the scope of this European standard (see EN 1634-1).
Single-axis hinges are required to satisfy the essential requirements of safety in use. Therefore, only grade 1 is identified.
Grade 0: no defined corrosion resistance.
Grade 1: mild resistance
Grade 2: moderate resistance
Grade 3: high resistance
Grade 4: very high resistance
Security – 2 Grades Identified
Grade 0: not suitable for use on burglar-resistant door assemblies
Grade 1: suitable for applications requiring a degree of security. Annex C of this European standard details the hinge grade to use for the level of security required.
Hinge grade - 14 Grades Identified
