The PAUT IIW Block, made in accordance with ISO 19675 was designed by an international committee of NDT experts with the express purpose of creating a globally accepted, standardized block for Phased Array Ultrasonic calibrations. Before the development of this spec, there were no international standards describing a specific block for calibrating PAUT systems.

Dimensions: 25mm wide 100mm x 300mm ( W x H x L), with 100mm and 50mm radius.

ISO19675:2017 specifies the requirements for the dimensions, material and manufactures of a steel block for calibrating ultrasonic test equipment used in ultrasonic testing with phased array technology.

Material: carbon steel 1018, stainless steel 304/316, duplex stainless steel 2205,aluminum 6063/7075,nodular cast iron and other materials.

The process starts with high-quality, fine-grained steel, produced in a special size by our preferred mill. Material selection is followed by heat treatment, flaw detection, material attenuation check, material velocity checks (longitudinal and transverse wave,) machining and surface finish preparation, block identification, in-house nickel-plating, and preparation of a comprehensive documentation package.
