ASTM Distance Amplitude Block Set of 19 (Metric Version) ASME SA516 Gr 70
ASTM E428 Distance Amplitude Calibration Blocks Set of nineteen flat-bottom hole blocks used to determine the relationship between metal travel distance (MTD) and signal amplitude. All blocks have the same size flat-bottom hole and varying MTD. Hole diameter must be specified when ordering (1.2mm, 2mm or 3.2mm). In accordance with ASTM E428. Includes our NIST traceable dimensional certification report, ultrasonic inspection report and response plot from Tactic Inc, and the certified material test report. Note that we use a 5.0 MHz quartz transducer for block characterization as required by ASTM E127, Section 11.
Geometry: Set of 19 blocks which contain hole diameters of 1.2mm, 2mm and 3.2mm with metal travel distances of: 1.5mm, 3mm, 6mm, 9mm, 12.5mm, 16mm, 19mm, 22mm, 25mm, 32mm, 44.5mm, 57mm, 70mm, 82.5mm, 95mm, 108mm, 120mm, 133mm and 146mm.
Dimensions: Metal travel distances are: 1.6mm, 3.2mm, 6mm, 9.5mm, 12.5mm, 16mm, 19mm, 22mm, 25mm, 32mm, 44.5mm, 57mm, 70mm, 82.5mm, 95mm, 108mm, 120mm, 133mm and 146mm. Block diameter is 50mm.
