ISO 15708 and Industrial CT Scanning's NDT Capabilities
Applied Technical Services performs computed tomography (CT) testing to ISO 15708. CT scanning is one of the most versatile nondestructive testing (NDT) methods commercially available. Under the steady hand of our technicians, this method can produce high-resolution 3D models composed of several thousand radiographic images showing cross-sections of the subject from every conceivable angle, elevation, and orientation.
ATS’ advanced equipment allows us to capture detail at the microscopic level, allowing our technicians to detect flaws in their earliest stages. The 3D aspect of the model — when combined with the precision and fidelity of scans produced by our sensitive instruments — brings a new dimension to our nondestructive capabilities, as it allows our technicians to measure defects volumetrically. Furthermore, the X-ray component of a CT scan displays any internal flaws with the same level of detail as surface discontinuities. Finally, rendering internal features with such precision enables technicians to measure material thickness to microscopic precision. Our computed tomography labs can achieve this list of nondestructive applications by completing a single scan, making CT the most comprehensive NDT method for components that clients can ship and can fit inside our chamber.
We maintain the following two CT chambers — one in Greenville, SC, and one in our Marietta headquarters:
- Northstar Imaging X5000
- Minifocus 450kV X-ray emitter
- 0.016” Focal spot at 3mA
- Dual-energy capability with 225kV Microfocus emitter (focal size as small as 0.0002” based on voltage)
- Multi-Axis manipulator arm (z, x, rotation, tilt), supports 250 lbs
- Fine manipulator angle control (0.001 of one degree) allows for
- CT system scans with spiral acquisition pattern to capture elongated objects that cannot otherwise fit within a single exposure
- Zeiss Metrotom 1500
- 225kV micro-focus emitter
- Chamber supports samples up to 23.6 in (600mm) high x 11.75 in (300mm) diameter
- Weight limit of 110 lb (50kg)
- Annual calibration by the A2LA
- Certified to accuracy within 4.5 micrometers
The ISO 15708 standard sets out general guidelines for axial CT scanning, including recognized applications and best practices. We perform CT scanning to ISO 15708-3 for nondestructive examination, but conduct this method of testing for dimensional inspection, metallurgical, and forensic investigation applications as well. Our computed tomography specialists scan according to several standards beyond ISO 15708, as well as client specifications.
