Feature:

It is used for calibration and confirmation of visual observation conditions.
It is used to select the brightness, distance, and speed at which the required line pair can be identified.
When creating an image record, if the required line pairs can be identified on the image, they can be regarded as the equivalent of a visual image record.

Specification:

Pair of colored lines used in the survey.

Feature:

The foaming liquid used is tested under the default foaming pressure (differential pressure from atmospheric pressure, 5×103 Pa) or less.
The test specimen is attached to a container with small holes (5 mm dia.) or a test plate using adhesive aluminum foil tape to cover the small holes.
In the case of the pressurization method, the minimum foaming pressure at which foaming occurs through the holes in the specimen is checked by sequentially applying pressure.
For the vacuum method, the test plate to which the specimen is attached is covered with a vacuum box and evacuated, and the minimum foaming pressure at which foaming occurs through the holes in the specimen is checked.

Specification:

Name: BL 30/100

BL: Indicates a foam leakage test.
30: Indicates a pore size of 30µm.
100: Thick plate 100µm is shown.

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.
