Informal document: INF.14 (ISO) (ISO standard 16418:2006 on acoustic emission testing (AT) for periodic inspection) 57. Some experts did not support the proposed deletion of NOTE 2 under 6.2.1.6.1(d) because they considered that the use of testing methods equivalent to the hydraulic pressure test should remain under the control of the competent ...

For Acoustic Emission Testing, the ASTM committee determined the test load must be more than the unit’s rated capacity but less than what would cause damage to the unit. For the test, the unit is loaded at a uniform rate between 10-20 lbs f/s and then held for a period of time, then the load is removed and the cycle is repeated.
