TABLE 1 BSEN 1935:2002
Note: These fourteen classes cover the majority of applications. The masses are based on the use of three hinges per leaf. If two hinges are used the masses listed should be reduced by on-third.

Cooke Brothers Phoenix architectural hinges are classified under BSEN 1935:2002, and are being developed to meet future international standards on their publication, see the following page.

These are specifications for the strength and durability of metal hinges for side hung applications and dimensional requirements for template drilling. The EN grade is given according to the maximum mass of the hinged leaf with which they will be used and the maximum annual number of operations.

It is important to remember that the weight of the door hardware and any glass used, can significantly increase the mass of a door and should be taken into account when determining which hinges to specify.

Door closers also increase the loading on hinges; if a door closer is fitted, it is recommended that the effective door mass be assumed to be 20% greater than the actual door mass. Backcheck closers impose even more load and the mass of the door should be assumed to be 75% greater than the actual mass.
