Dye Penetrant Testing (DPT)
Dye penetrant testing is widely used to detect surface breaking flaws in both ferrous and non ferrous parts.
Highlighting Surface Anomalies
Dye Penetrant Testing (also known as Liquid Penetrant Testing) is a low-cost, widely accessible inspection method used to locate surface-breaking defects in non-porous materials. Capable of revealing tight cracks and pores, it ensures structural reliability in critical components.


Versatile Analysis Methods
Dye penetrant testing can be used both on site or in a laboratory application with either colour contrast or fluorescent techniques. At NDT Services we can provide approved water washable or post emulsifiable systems in our laboratory, with full pre-cleaning and post-test preservation capabilities.
- Colour contrast techniques
- Fluorescent techniques
- Water washable or post emulsifiable systems
- Full pre-cleaning & post-test preservation

Laboratory & On-Site Testing
In the laboratory it is particularly suitable for the inspection of batch quantities of machined parts and is a cost effective and efficient method of testing for surface breaking discontinuities. With our capacity and capability and our collection and delivery service, we can assure you of a quality service with a fast turn around.
