Hinges for doors and EN 1935:2002 CE marking

Hinges for doors and EN 1935:2002

Often ignored by the end customer, that when choosing door and window informs on the handle, on the lock, the color, the heat and sound abatement, the duration of the paint over time etc.

Little considered by producer, be it industrial or artisan, who, accustomed to always use the same product, does not inform about news from the market, aided by the fact that “the end customer does not matter which hinge” anyway.

Among all components and particularly in hardware for doors and windows, the hinges have always been the least considered.

The European and international standards today impose different choices, though. Choices that see the hinge at the center of the production process and design of the door and the window. A process that needs to be performed in the long run.

The architecture then, for several years has been changing its approach to construction. Increasingly we see large stained glass windows. More and more doors sized outside the standards. Increasingly subtle yet thick profiles. Triple glazing-room, armored glass. Heavier doors!

So the hinge, fulcrum of rotation and motor of the door, gains importance and should be carefully considered during design and development.

Hinge functions

The hinge is the fastener and port connection to the frame. It allows the doors to open and close and thus makes possible the movement of people inside the rooms. They must be sufficiently sized to allow the safe movement of the door throughout his rotation.

The hinge, positioned on the opposite side to the lock, is an important element for the security of a home. We are used to think that the robbers come into our house, picking up the lock, but nothing is further from the truth. If you install multi-point and anti-burglar locks of last generation, most likely the attacker will focus his attention on the hinges.

The hinge is the pivot of the door. A rotation that should be smooth and without squeaking. A rotation that must be guaranteed in the long term and far beyond the statutory warranty terms. This is especially important in public buildings where the frequency of door openings is very high and the ways people open and close the doors are very different.

The hinge is also a design element inside the door and this contributes to the enhancement of the environment in which the door is installed. The material, finish, the right proportion of size, placement and number of hinges to be used, creating huge differences on the finished product.

Why choose a CE marked product

While it is true that a certified product is a product tested, the reverse is not true! And you should pay special attention to this difference when you go looking for a CE certified product as, what makes the difference is the presence or absence of a certificate from an accredited institution and the presence or absence of CE marking. It seems obvious to say, but it really isn’t.

A test report issued by an accredited institution (such as IFT, ICIM or others) is not a CE certification but only the first step to get it. The legislation provides for a production under control, yearly or half-yearly audits by external entities that encounter the quality standards required by the law, regular internal tests that ensure the maintenance of production standards and much more.

Choosing a CE marked product in short is a guarantee that the same item purchased yesterday, today and tomorrow is subject to shared standards and his performances are always the same regardless of the production lot.

It is therefore important not to be fooled by enticing iconographies and pursue this issue, requesting a copy of the certification of CE marking.

In addition, from July 1, 2013 entered into force the Regulation of construction products CPR 305/2011 that provides for all articles (including hinges) that the manufacturer set up a declaration of performance of its CE marked products.

Will therefore be useful to contact the manufacturer and request together with the certificate of CE marking of the product, even the “Declaration of performance”.



Standard EN 1935:2002

What does the European standard EN 1935:2002 rule? The CE marking is the basis for the free movement of goods within the European Union. This also applies to the hinges for doors and windows. According to the document 101, issued by the European Committee for Standardization (CEN) and with the adoption of standard EN 1935:2002 by the Member States of the European Union, the CE marking is mandatory for the hinges that are used on fire doors, smoke doors and on doors along escape routes.

European standard EN 1935:2002 specifies test procedures and requirements for single axis hinges with plates and with stems for doors and windows, and classifies them with an 8-digit code.

Classification:

head

1. Category of use – grades 1-4

Grade 1

Light use. Hinges on interior doors or windows or other places to stay and in buildings where there is a low frequency of use and attention from you, and low risk of accidents or misuse.

Grade 2

Medium use. Hinges on interior doors or windows or other places to stay and in buildings where there is an average usage frequency and some care on your part, but where there is a risk of accidents or misuse.

Grade 3

Heavy use. Hinged doors in buildings where there is a high frequency of use by the public or others, with little care and a high risk of accidents or misuse.

Grade 4

Very heavy use. Hinges on doors subject to use frequently violent.

2. Endurance Test – Grades 3, 4 and 7

  • Grade 3: 10,000 cycles (one hinges for Windows);
  • Grade 4: 25,000 test cycles (hinges for doors and Windows);
  • Grade 7: 200,000 test cycles (hinges for doors).

3. Test door mass – grades 0–7

  • Grade 0: 10 kg;
  • Grade 1: 20 kg;
  • Grade 2: 40 kg;
  • Grade 3: 60 kg;
  • Grade 4: 80 kg;
  • Grade 5: 100 kg;
  • Grade 6: 120 kg;
  • Grade 7: 160 kg.

4. Fire Resistance – grades 0, 1

  • Grade 0: not suitable for fire/smoke resistant door assemblies;
  • Grade 1: suitable for fire/smoke resistant door assemblies (see EN 1634-1).

5. Safety – Grade 1

Single-axis hinges are required to satisfy the essential requirements of safety in use. Therefore, only grade 1 is identified.

6. Corrosion resistance – grades 0–5

  • Grade 0: no specific resistance to corrosion;
  • Grade 1: minimum resistance;
  • Grade 2: moderate strength;
  • Grade 3: high resistance;
  • Grade 4: very high resistance;
  • Grade 5: very high resistance.

7. Security – Grades 0, 1

  • 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.

8. Hinge Grade – Grades 0–14

Fourteen grades are identified in this European standard. Below is a summary table with all grades.
