Describes a procedure for the acoustic emission testing of elevating work platforms incorporating fibreglass-insulated reinforced plastic booms, to establish the structural integrity of the boom. It also specifies rejection criteria. Requirements are given for the test equipment, instrument performance tests and instrument calibration.

This Standard describes a procedure for acoustic emission (AE) testing of elevating work platforms (EWPs) incorporating fibreglass-insulated reinforced plastic (FRP) booms. The acoustic emission test method is used to establish the structural integrity of the boom by detecting and locating any acoustic emission source areas. Verification of whether structural defects are the cause of acoustic emission sources may require the use of other non-destructive test (NDT) methods such as radiography, ultrasonics, liquid penetrant and visual inspection.This Standard is based on four minute load hold periods which may not give 100% strain equalization in the fibreglass. Longer holding cycles of up to 35 minutes are employed when the acoustic emission continues at the end of any load hold period.
