ASTM Distance Amplitude Block Set of 19 (Inch Version) 4340 Steel

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 (3/64”, 5/64” or 8/64”). 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 3/64", 5/64" or 8/64" with metal travel distances of: .06",.12",.25",.37",.50", .62",.75",.87",1.0",1.25", 1.75", 2.25", 2.75", 3.25", 3.75", 4.25", 4.75", 5.25" and 5.75".

Dimensions: Metal travel distances are: .063”, .125”, .250”, .375”, .500”, .625”, .750”, .875”, 1.000”, 1.250”, 1.750”, 2.250”, 2.750”, 3.250”, 3.750”, 4.250”, 4.750”, 5.250” and 5.750”. Block diameter is 2.0".
