2:2Beaver Architectural Ironmongery LtdTechnical NotesBS 1935 : 2002 Building Hardware Single-Axis Hinges This European Standard has replaced the previous product performance standard BS 7352: 1990. It covers single axis hinges and lift off hinges for use on windows and doors, and classifies them with an 8-digit code. The standard requires that hinges manufactured for use on fire-resistant or smoke control doors or locked doors on escape routes should be marked with the manufacturer's name or trademark or other means of identification, the hinge grade and the number of the European Standard (BS EN 1935).1st Digit2nd Digit3rd Digit4th Digit5th Digit6th Digit7th Digit8th DigitCategory of useNumber of test cyclesTest door massSuitable for fire doorsSafetyCorrosionresistanceBurglarresistanceHinge grade (Door mass / no. of operations)1 - Light3 - 10,000(1 - 8)0 - No1 - Required0 - None0 - No1 - 10kg / 10,0002 - Medium4 - 25,0001 - Yes 1 - Mild1 - Yes2 - 20kg / 10,0003 - Heavy7 - 200,0002 - Moderate3 - 20kg / 25,0004 - Severe3 - High4 - 20kg / 200,0004 -Very high5 - 40kg / 10,0006 - 40kg / 25,0007 - 40kg / 200,0008 - 60kg / 10,0009 - 60kg / 25,00010 - 60kg / 200,00011 - 80kg / 200,00012 - 100kg / 200,00013 - 120kg / 200,00014 - 160kg / 200,000Hinge installationNormally three hinges are fitted to each door leaf in accordance with BS 4787 part 1. For doors exceeding 2100mm in height a fourth hinge should be used. Care must be taken to ensure that the hinges are correctly aligned and fixed securely to door and frame. The screw holes should be piloted and screwheads must be flush with the hinge face to ensure that the door closes properly.Hinge positioningIt is usually acceptable to line up the centre hinge with the door handle.Equally spaced hinges will minimise warping which may occur in environments with extremes of temperature or humidity on either side of the door. Positioning the third hinge nearer the top of the door improves load bearing. This is recommended where the hinges are operating near their load bearing maximum or where door closers, particularly backcheck door closers, are in operation and the door has a high frequency of use.Lift-off and Rising/Falling hingesLift-off, rising and falling hinges are handed and must be specified to operate in either a clockwise closing or an anti-clockwise closing direction. The leaf with the pin in the upwards position must be fitted to the frame. Hinge operation is either clockwise closing or anti-clockwise closing and should be specified using the ISO 5 clockwise closing and ISO 6 anti-clockwise closing convention.250200=====250250250250200200250ClockwiseclosingAnticlockwiseclosing
