New standard for matrix array ultrasonic testing

New standard for matrix array ultrasonic testing

ASTM International has responded to the rising demand for matrix array ultrasonic testing (MAUT) standards by publishing a new standard practice for matrix array ultrasonic testing. This new standard, known as ASTM E3370-22, is designed for use with non-phased matrix array transducers, such as the Dolphicam2 platform. Unlike other transducers, these operate with an isotropic matrix array of elements with a small pitch and high count, making them capable of live C-scan generation.

Previously, MAUT had been underrepresented by international standards as it sat between conventional straight beam ultrasonic testing and phased array UT. The new standard aims to fill this gap by providing a starting point for building inspection procedures and detailing all aspects that need to be considered. It covers two modes of operation: test procedure A (pulse echo) and test procedure B (through transmission). Additionally, general considerations such as quality assurance provisions, test apparatus, physical reference standards, and reporting requirements are discussed in detail.

Jason Smith, Defense CEO at Dolphitech, expressed his delight at the publication of this standard and believes it will pave the way for further matrix array UT standards, with ASME and ISO standards already in the pipeline. Jack Lambert, Technical Sales Manager at Dolphitech, also praised the new standard, stating that it is essential to keep up-to-date with emerging technologies to ensure that international standardization efforts remain relevant to industry practices. Overall, this new standard is expected to be a useful guide for both new and existing users of MAUT.
