AMS-STD 2154, ASTM E2375 & ASTM E127
AMS stands for Aeronautical Material Specification. AMS-STD 2154 was developed from MIL-STD 2154 a US Department of Defence military standard. It provides a uniform method for the ultrasonic inspection of wrought metals and wrought metal products.
ASTM E2375 is an equivalent standard for the calibration process using a reference block. E127 refers to the standard level of precision in the predrilled faults within the calibration blocks themselves.
The Importance of Calibration
Bar stock must be tested for faults through ultrasonic testing. In order to prove the validity of the data received from the ultrasonic set, we must perform a calibration test. This involves scanning the calibration block in order to find premade faults within a calibration reference block. These faults are drilled to different depths, in accordance to the ASTM E127 standard and upon scanning – should the set find the fault – we can prove that the settings on the ultrasonic set can be used.
Not all bar stock is made from the same material and neither are the calibration blocks! Due to the structure of different metals, ultrasonic waves react differently within different metals. It is therefore key to hold multiple sets of calibration blocks in different metals, the most common being steel, aluminium and titanium. Once the ultrasonic set finds the premade fault in the specific calibration block, testing can be undertaken as normal.
