Acoustic Emissions testing is a procedure designed to test the structural condition of fibreglass booms. Fibreglass, unlike steel, can not easily be inspected for fatigue, wear or many other defects. The procedure requires placing a number of sensors along many positions of the boom and applying twice the unit's rated load two times, and in up to two positions. By examining the number of acoustical noises caused by fibres breaking on the pulls it is possible to determine if the fibreglass is in good condition or likely to fail in the near future.

Rocwin is still level 2 certified to perform Acoustic Emissions Testing, but we have decided it is no longer economically feasible to continue due to lack of demand in the industry. We can, however, refer you to someone capable.
