Hinges are an important product in door hardware, it affects the door’s usage. Different countries have different standards for hinges. Understanding these standards helps us understand industries’ and brands’ production thresholds and quality control standards. This article mainly discusses the US standard, EU standard, and Chinese standard for hinges.
American Standard Hinges
Features of American Standard Hinges:
- Material: usually steel or stainless steel, with high load-bearing capacity.
- Size specification: large size, 4 inches or more, thickness of 3.5 mm or more.
- Installation method: use large-size screws for installation, stable and safe.
- Applicable scenarios: suitable for heavy doors and windows, etc.
- Standard formulation: The standards for American standard hinges are usually formulated by the American Standards Association (ANSI) or the Building Hardware Manufacturers Association (BHMA), including the performance and durability of hinges.
Introduction to American Standards
ANSI/BHMA A156.1 Mainly for the evaluation requirements of butt hinges, including durability test, vertical and horizontal wear test, overload test, friction test, and salt spray test. If it is a certified product, there must be a test report that meets the standard requirements, and its product model must be included in the ANSI/BHMA CPD-certified product list in the past three years.
ANSI/BHMA A156.4 For pivot hinges, it also includes the above tests. Including technical requirements and test methods for door closers, including pivot hinges.
ANSI/BHMA A156.17 The test of spring hinges, including cycle test, etc.
ANSI/BHMA A156.20 For the evaluation requirements of strap and tee Hinges, various tests including durability test are carried out to ensure the performance and quality of these types of hinges.
ANSI/BHMA A156.26 requires various tests including durability test of continuous hinges.
EN Standard of Hinges
Features of the European Standard Hinge:
1. High standard certification: reliable product quality.
2. Super load-bearing capacity can meet various load-bearing needs.
3. stainless steel ball-bearing design: hinge use smooth, silent.
4. Durability: through 240 hours of salt spray test, good corrosion resistance effect.
5. Good anti-corrosion performance.
Introduction to the EU Standard for Hinges
European standard designation group is the European Committee for Standardization (CEN) member states, founded in Paris, France in 1961.
EN 1935: 2002 for single-axis hinge test requirements, including durability test and deformation test, etc. It is one of the most used standards in the construction industry. A certified product must have a test report that meets the standard’s requirements. And it has to obtain CE marking.
Chinese Standard of Hinges
Features of the CNS Hinges:
- Material and size: applied SUS 304 stainless steel. The thickness is usually 3 mm. High strength and corrosion resistance.
- Surface treatment: uniform and delicate color. A small deviation of hole position and hole distance.
- Functionality: smooth use, mute. Currently there are products such as oil-free hinges.
- Durability: good quality materials, production process upstream, hinge service life.
Introduction of the Standards
1. QB4595.1-2013 -ordinary type hinge. It has three grades, grade 1 is the highest. Including requirements for size and deviation, axial and radial clearance, service life, load bearing, and corrosion resistance. Applicable to general fine residential or office buildings and other common public and commercial construction scenarios such as wooden doors or fire doors.
2. JG/T 125-2017 -hinge .It has three grades, including door and window hinge requirements: Ⅰ and Ⅱ for doors, and Ⅲ for windows. Standard reference to the European standard. Increased hinge life test after the door deformation requirements, impact requirements, etc., applicable to schools, hospitals, and other doors.
3. QB/T4063-2010 -ball bearing hinge. divided into three grades, grade 1 is the highest grade. It has the highest requirements for hinges among these CNS standards. It is formulated according to the American standard and has high requirements for hinge thickness, life test, load-bearing test, and friction. It is suitable for heavy-load doors or doors with large traffic.
