Use Purpose

These gauges are designed to efficiently classify the images of flaws in radiographic photographs, and are each based on the following three standards:

1. JIS Z 3104-1995 ‘Radiographic Testing Method for Steel Weld Joints’
2. JIS Z 3105-2003 ‘Radiographic Testing Method for Aluminum Weld Joints’
3. JIS G 0581-1999 ‘Radiographic Testing Method for Cast Steel Products’.

Use Purpose

For Magnetic Particle Inspection Standard Test Piece （JIS Z 2320-1）

1. Confirmation of the strength and direction of the magnetic field applied to the test surface.
2. Performance inspection of equipment, magnetic powder, and inspection liquid.
3. Setting the effective range for flaw detection.
4. Confirmation of test operations and conditions.

1. Made-to-order products may take several months to deliver.
2. For the A1 and A2 type standard test pieces, the model number on the left of the slash indicates the depth of the artificial flaw, and on the right, the thickness of the plate (in micrometers).
3. For category 2 of Type A standard test pieces, the strength of the magnetic field in which the magnetic powder pattern appears is higher than in category 1.
4. Type C standard test pieces are used when it is difficult to apply Type A standard test pieces dimensionally, for example, in narrow areas such as the bevel surface of a weld.
5. Regardless of the order quantity, please bear the uniform packaging and shipping costs.

Standard Test Piece （JIS Z 2345-1 ～ JIS Z 2345-4）

Use Purpose of STB Series

1. To measure the position of the reflection source, it’s essential to adjust the time axis.
2. This also involves calibrating the measurement range. For accurate echo height readings from the reflection source, fine-tuning the flaw detection sensitivity becomes crucial.
3. One must also conduct thorough inspections of the flaw detection equipment’s characteristics and performance, ensuring precise measurement of performance traits.

Specifications

Note) The test piece storage case will be changed from aluminum to resin for shipments starting from August 1, 2019.

Use Purpose

（JIS Z 2340）

• This tool is used to calibrate and confirm visual observation conditions.
• It helps select the necessary observation brightness, distance, and speed to identify line pairs required for inspection.
• Furthermore, when creating image records, if the necessary line pairs are separable and identifiable on the image, it can be considered equivalent to visual observation.

Use Purpose of BL 30/100

• The JIS Z 2329 standard outlines performance criteria for foaming liquids.
• Users must apply a test piece to ensure the liquid foils at a pressure differential from atmospheric pressure of 5×10³ Pa or less.
• They attach the test piece to a container or test plate, sealing the 5mm holes with adhesive aluminum foil tape.
• For the pressurization method, they increase the pressure step by step to find the minimum required to generate bubbles through the test piece’s holes.
• For the vacuum method, they cover the test plate and test piece with a vacuum box, then evacuate the air to identify the lowest pressure at which bubbles appear.

Remarks （JIS Z 2329）

1. The material of the foaming liquid test piece is a metal that is difficult to corrode.
2. The display of the foaming liquid test piece is as follows.
