''Helmet test specifications were originally developed from considerations of the maximum forces that the human body could survive. The primary tests were those related to stonefall protection rather than swinging falls. This does not preclude the manufacturer designing a helmet primarily designed for rock climbing, but it will not be tested for this, and it will still have to pass the standard helmet tests. In due course we may see the development of two standards, one for mountaineering helmets and another for cragging helmets.''
