Aluminum ASTM Wire Type IQI-02A

2 in Aluminum Wire-Type Image Quality Indicator (IQI) for Industrial Radiographic Testing
SKU: 13.301-A

Overview

The Aluminum ASTM Wire Type IQI-02A is a 2 in wire-type Image Quality Indicator (IQI) designed for verifying radiographic image quality and sensitivity during industrial X-ray and gamma-ray testing of suitable aluminum and related low-density materials.

The IQI uses a series of precision aluminum wires with controlled diameters. When the indicator is included in the radiographic setup, the visibility of the required wire on the completed image provides a reference for determining whether the radiographic technique has achieved the required level of image quality.

Its compact 2 in configuration makes it suitable for welds, castings, aerospace components, aluminum structures, fabricated components, and other applications where an aluminum wire-type IQI is required by the applicable radiographic procedure.

What's Included

Note: Radiographic source equipment, film, digital detector, cassette, lead screens, identification markers, film-processing equipment, and other RT accessories are not included unless specified separately.

Key Specifications

Wire-Type IQI Configuration

The IQI contains multiple precision wires with controlled diameters. Each wire provides a known dimensional reference that can be evaluated on the resulting radiographic image.

Wire-type IQIs allow the inspector to:

• Verify achieved radiographic sensitivity

• Establish an image-quality reference

• Determine the smallest required visible wire

• Confirm that the exposure technique provides sufficient detail

• Compare results with applicable inspection requirements

• Document radiographic technique performance

The exact required wire visibility depends on component thickness, inspection technique, applicable code, and written procedure.

How the IQI Works

During radiographic inspection:

1. Select the correct IQI material and configuration.

2. Position the IQI according to the applicable radiographic procedure.

3. Complete the X-ray or gamma-ray exposure.

4. Process the film or acquire the digital radiographic image.

5. Locate the IQI image.

6. Evaluate individual wire visibility.

7. Determine whether the required image-quality level has been achieved.

The IQI verifies image quality, not the acceptance or rejection of the component itself.

Typical Inspection Workflow

The IQI can be incorporated into a radiographic workflow involving:

• Component preparation

• Radiation source selection

• Detector or film positioning

• IQI selection

• IQI placement

• Exposure calculation

• Radiographic exposure

• Film processing or digital acquisition

• Image-density or digital-image evaluation

• Wire visibility assessment

• Discontinuity interpretation

• Inspection documentation

Placement Considerations

For reliable image-quality verification:

• Select the correct IQI material

• Position the IQI according to the applicable procedure

• Place it as close as practical to the area of interest

• Use source-side positioning when required

• Follow procedural rules when film-side placement is necessary

• Maintain the required wire orientation

• Avoid locations where geometric features could obscure the wires

• Clearly identify the IQI on the radiographic image

Improper IQI placement may invalidate image-quality verification.

Inspection and Interpretation

When reviewing the completed radiograph:

• Confirm that the IQI is clearly represented

• Locate individual wire images

• Determine the smallest wire that can be reliably resolved

• Compare wire visibility with the required sensitivity

• Verify any applicable image-density or digital-image requirements

• Record the IQI identification

• Document the required sensitivity information

• Retain the inspection image according to the applicable quality procedure

Interpretation should be performed by qualified personnel under proper viewing conditions.

Compatibility

Compatible with:

• Industrial X-ray systems

• Appropriate gamma-ray radiography systems

• Computed radiography systems

• Film cassettes

• Digital detector panels

• Radiographic identification systems

• Film viewers

• Digital image-review workstations

• Aluminum-component RT procedures

• Field and laboratory radiographic inspection programs

The selected IQI should match the inspected material group and governing radiographic requirements.

Care and Handling

• Handle the IQI carefully

• Avoid bending the wire assembly

• Do not crush or deform individual wires

• Keep the IQI clean

• Protect wire identification markings

• Do not grind, file, or modify the wires

• Inspect for corrosion or physical damage before use

• Store flat in a protective case

• Keep away from heavy or sharp tools

• Replace the IQI if wires become damaged, distorted, missing, or illegible

Damage to individual wires can affect the validity of the radiographic sensitivity evaluation.

Safety Considerations

The IQI itself does not generate radiation, but it is intended for use during industrial radiographic inspection.

When performing RT:

• Use trained and authorized radiographic personnel

• Establish controlled radiation areas

• Use appropriate radiation survey instrumentation

• Wear required personal dosimetry

• Prevent unauthorized entry during exposure

• Follow source-handling procedures

• Confirm radiation levels are safe before retrieving equipment

• Follow all applicable site and regulatory radiation-safety requirements

About Wire Image Quality Indicators

Wire Image Quality Indicators are precision reference devices used in industrial radiography to demonstrate the image quality achieved during an exposure. By providing multiple known wire diameters, they allow inspectors to verify that an X-ray or gamma-ray image provides sufficient sensitivity for the intended examination.
