PCN Level 3 Main Method

Radiographic Testing – Level 3 – Online

Radiographic testing, or radiography, is one of only two ISO 9712 inspection techniques that is considered volumetric. In this context volumetric implies that the full body of the component is subjected to testing.

Visual Testing Level 3 – Online

Visual inspection is a form of Non-Destructive Testing defined as the monitoring of specific parameters by visual and optical assessments of test objects and surfaces using the visible portion of the electromagnetic spectrum.

Magnetic Particle Testing – Level 3 – Online

Magnetic Particle Testing is used for the detection of surface and near-surface discontinuities in ferromagnetic materials such as iron, nickel, cobalt and some of their alloys. It can be primarily used for crack detection. This method is applicable to all metals which can be strongly magnetized - ferritic steals and irons, but not generally austenitic steels.

Ultrasonic Testing – Level 3 – Online

Ultrasonic Testing (UT) is one of only two ISO 9712 inspection techniques that is considered volumetric. In this context volumetric implies that the full body of the component is subjected to testing.

Penetrant Testing – Level 3 – Online

Penetrant Testing can also be referred to as Dye Penetrant Inspection (DPI) or Liquid Penetrant Inspection (LPI). It is a low cost inspection method used to reveal surface breaking defects, commonly used on materials such as metals, glass or plastics (providing they are not porous). LPI is used to detect casting, forging and welding surface defects, such as cracks, surface porosity or fatigues cracks on in service components, by the bleed-out of a coloured or fluorescent dye from the said defect.
