The Standard for Single Axis Hinges, BS EN 1935:2002, provides details on product types, classification by use, test cycles, door mass, corrosion resistance, as well as definitions, product performance requirements, test apparatus, test methods and marking of products. In addition, the standard also includes details for people with special needs.
The scope of the standard specifies requirements for single-axis hinges, for windows and doors opening only in one direction, whose rotation axis is no more than 30mm away from the sash or door. It also covers for both fixed pin and lift-off hinges.
The European standard classifies single-axis hinges using an 8 digit coding system. This is also in line with standards for most other items of building or architectural hardware.
8 Digit Classification
