1. The realization of
furniture hinge of standard classification coding system:
[European Standard: EN1935]
This standard includes product type, use level, inspection times, door weight, corrosion resistance, product performance requirements, testing equipment, testing methods and product identification. The annex to this standard includes diagrams and supplementary instructions.
2. area
The standard includes a variety of hinges, including single hinges and lifting hinges used in doors and windows.
The classification rate code of the European standard hairpin chain is represented by an 8-digit code, as shown below:
1. According to the frequency of use and the error rate, it is divided into light, medium, heavy, and overweight 1, level 2, level 3, and level 4.
2. According to the service life, it is divided into three levels, such as 3, 4, and 7. These 7 levels require 200,000 times
3. According to the weight of the door, there are 8 grades from 0-7, while the weight of the 6-level door is 120KG-2.
4. Whether to use anti-smoke and anti-smoke doors, it is divided into 0 and 1; 0 means not applicable.
5. All have safety requirements, and the classification code is 1.
6. All have safety requirements, and the classification code is 1.
7. According to the anti-theft performance, it is divided into 0 and 1, and level 0 means no anti-theft requirements.
8. Divided into 14 levels according to the carrying capacity. Level 13 is a high-intensity use frequency, with a service life of 200,000 times, and the hinge can carry 120KG.
Furniture hinge coding system description
First place: Use level (4 levels in total)
Level 1: Light use. When used in buildings, houses or other residences, the frequency of use is low, and the use will be careless. If used improperly, the risk will be reduced.
Hinge encoding system explained
No.1: Use level (4 levels in total)
Level 1: Light use. Used in buildings, houses or other residences, the frequency of use is low and the use will be less careful, if used improperly, the risk is less.
Level 2: Medium use. Used in buildings, houses or other residences, the frequency of use is medium and the use will be less careful, if used improperly, the risk is small.
Level 3: Heavy use. Used in buildings, the frequency of use is high, the use is negligent, improper use, there will be risks.
Level 4: Super Heavy use. It is installed on a door that is used very frequently and is easily impacted by external forces.
No.2: Durability (three levels in total)
Level 3: 10,000 inspection cycles (only applicable to window hinges)
Level 4: 25,000 inspection cycles (applicable to door/window hinges)
Level 7: 200,000 inspection cycles (only for door hinges)
No.3: Door weight detection (8 levels in total)
Level 0: The detection door weighs 10KG
Level 1: Detection door weighs 20KG
Level 2: Detection door weighs 40KG
Level 3: Detection door weight 60KG
Level 4: Detection door weighs 80KG
Level 5: Detection door weighs 100KG
Level 6: Detection door weight 120KG
Level 7: The inspection door weighs 160KG
No.4: fire resistance (2 levels in total)
Level 0: Not applicable to fire/smoke doors
Level 1: Suitable for fire/smoke doors
No.5: safety-personal safety (1 level in total)
Level 1: All hinges meet the basic requirements for safe use, so there is only level 1.
No.6: Corrosion resistance (5 levels in total)
Level 0: Corrosion resistance is not required
Level 1: mild corrosion resistance
Level 2: Moderate corrosion resistance
Level 3: High corrosion resistance
Level 4: Extremely high corrosion resistance
No.7: Security-anti-theft (2 levels in total)
Level 0: Not applicable to anti-theft doors
Level 1: Suitable for anti-theft doors
No.8: Load-bearing
Level: Divided into level 1, level 2, level 3 to level 14
Door weight: sorted by level: 10, 20, 20, 20, 40, 40, 40, 60, 60, 60, 80, 100, 120, 160 (KG)
Maximum usage times per year: sorted by level: 10.000, 10.000, 25.000, 200.000, 10.000, 25.000, 200.000
10.000, 25.000, 200.000, 200.000, 200.000, 200.000, 200.000 (times)
