Product Made in Japan
Manufacturer: Ultrasound

Feature:

These gauges are designed to efficiently classify images of flaws intransparencies.

Specification:

Each of these gauges is designed according to one of the following three standards:

1. JIS Z 3104-1995 “Radiation transmission test methods for steel welded joints
2. JIS Z 3105-2003 “Radiation transmission test methods for aluminum welded joints
3. JIS G 0581-1999 “Radiation transmission test methods for cast steel products

Standard Test Specimen for Magnetic Powder Testing (JIS Z 2320-1)

– In the model numbers of A1 and A2 type standard test pieces, the left side of the shaded line indicates the depth of the artificial defects and the right side of the shaded line indicates the thickness of the plate. (Unit: µm).
The strength of the magnetic field in which the magnetic powder pattern appears is higher for Type A2 standard specimens than for Type A1 standard specimens.
– Type C standard test piece is used when it is difficult to apply Type A standard test piece due to its size. Example: Narrow areas such as weld bevel surfaces.
