Hinges and pivots

Product catalog summary

Technical Specifications:
The document provides detailed technical information on hinges and pivots, focusing on their classification based on door opening direction. For right-hand doors, add 'D' to the reference, and for left-hand doors, add 'E'.

Standards and Compliance:
Hinges must comply with European Standard EN1935:2002 under the EU directive on construction products (89/106/EEC). Single-axis hinges require a CE conformity certificate for use in fireproof/smoke doors and emergency exits. JNF conducts internal resistance tests according to this standard.

Load and Usage Considerations:
Hinges are designed to support specific loads, influenced by door weight, dimensions, usage frequency, and installed accessories. It is recommended to use at least three hinges per door for safety, with a potential fourth hinge depending on usage.

Calculation of Hinge Requirements:
Step 1 involves determining the door's weight and necessary weight adjustments based on dimensions and usage. A formula is provided to calculate the percentage increase if the height-to-width ratio is less than 2. Step 2 involves selecting the hinge type based on the theoretical weight, which includes actual weight and increments for additional factors like door closers and usage frequency.

Hinge Classification:
Hinges are classified according to their intended use, ranging from light to severe, considering factors such as frequency of use and potential for misuse, with grades assigned accordingly.

Key Data from Tables:
The document includes tables detailing the relationship between door dimensions and weight increments, as well as hinge classifications based on usage conditions and endurance tests.

Hinge Usage Grades:
1. Grade 1 - Light Use: Suitable for doors and windows in areas with low usage frequency and minimal public access.
2. Grade 2 - Medium Use: For doors and windows in domestic and office settings with average usage and some risk of misuse.
3. Grade 3 - High Use: Designed for public buildings with high usage and a higher likelihood of misuse.
4. Grade 4 - Severe Use: For doors subject to frequent and intentional misuse.

Hinge Application Procedure:
1. Mark hinge positions as per the provided diagrams.
2. Place the first and second hinges 237 mm from the door ends.
3. The third hinge should be 370 mm from the first hinge.

Hinge Maintenance Recommendations:
1. Conduct systematic inspections and maintenance, especially for emergency doors.
2. Lubricate hinges annually or every 25,000 cycles.
3. Ensure screws are secure and replace if necessary.
4. Check for corrosion and ensure proper door alignment.

ECO Series Hinges:
1. Made from stainless steel EN 1.4372, suitable for most environments except coastal areas.
2. Economical due to lower nickel content and ISO 9001 quality control.

Standard Series Hinges:
1. Made from stainless steel EN 1.4301 or EN 1.4401, offering high corrosion resistance.
2. Suitable for environments requiring high durability.

3D Invisible Hinges:
1. Designed for heavy-duty doors, allowing three-dimensional adjustments.
2. Made from stainless steel or aluminum, suitable for frameless architecture.
3. Features include a maximum opening angle of 180 degrees and self-lubricating washers.
