It addresses the requirement for easy egress from all new build dwellings instigated by the National House Building Council by ensuring all doorsets are suitable for use with thumb turn cylinders and other easy egress hardware

Ball screws - Static and dynamic axial load ratings and operational life not-for-sale Typical applications are corrosion fatigue1 Scope This part of ISO 3408 specifies the calculation schemes for static and dynamic load ratings, and operational life, in order to obtain comparable values for the design and use of ball screws. NOTE The calculations have been based primarily on publications by Prof. G. Lundberg and A. Palmgren Acta Politechnica, mech. Eng. series Vol. I, No. 3, Stockholm, Sweden. Part 7, 1947. This part of ISO 3408 is applicable under the following preconditions:
