      Hi guys,
      Does anyone know of a standard that references 'pinch point' dimensions for handrailing?
      I.e The gap must be less than X, or greater than Y, but not between X and Y?
      Preferably Australian Standard?

      Cheers
      Dinga

      In the UK the standard for pedestrian railings (which is what I think you are asking for) - is BS-7818 - and below is a hyperlink to a copy of this standard. It covers the spacing of vertical members and the structural loading the frame work has to take.

      There is also a system called Visirail - which has got the vertical bars positioned in such a way - that it aids drivers see children more readily. In plan view of the railing the vertical bars - are set up - so that they are in a series of "parallel diagonals". The motorist is able to see through these "parallel diagonals" - and therefore see children more easily. From memory this system was patented.

      Hope this helps.
