The RST Contour Plus Level 2 back protector is tested to the higher standard set out under European standard EN 1621-2:2003. Alongside protecting the spine there is now considerable anecdotal evidence that wearing a certified back protector can significantly reduce trauma in a major accident as they reduce the effect of impacts on the ribs and lessen the blows to internal organs too. A CE Level 2 back protector transmits less than half of the force of an impact compared to a CE Level 1 back protector.
The RST Contour Plus Level 2 Back Protector can be fitted into any RST jacket and is now standard in all equipment in all 2016 pro series jacket.
European standard EN 1621-2:2003 defines two levels of performance for CE approved back protectors. The test apparatus and procedure is similar to that of EN 1621-1:1997 but with a different impactor and anvil configuration. The impactor is a rounded triangular faced prism, of length of 160mm, base 50mm, heigh 30.8mm and radius 12.5mm. The anvil is a radiused cylinder, with its axis orientated to the direction of impact, of height 190mm, diameter 100mm and rounded end radius 150mm.
Level 2back protectors: the average peak force recorded below the anvil in the tests shall be below 9kN and no single value shall exceed 12kN
