Four new tests have been developed for determining the strength and abrasion resistance of motorcycle riders’ clothing. These have been validated in ‘dummy-tests’ in a simulated accident, and by performing the tests on crash-damaged clothing. These tests, and others, have been combined in a test schedule for new clothing. The use of these tests and associated limit values and specifications are described. A small number of manufacturers have collaborated to produce designs and garments to provide the highest level of protection predicted to be possible in high speed accidents. These garments have been used to establish practical procedures for the tests and to show that the performance limit values can be achieved without radical changes to established designs and construction methods of motorcyclists’ clothing.
