An Introduction to Pinholes and Holidays – Porosity Detection
Corrosion is caused by two things – a steel substrate and oxygen, while contaminants such as water can accelerate the process. The coating is there to protect the steel from oxygen and contaminants. A flaw in the coating can leave the substrate poorly protected, or in some cases completely exposed.

How to set up an Elcometer Continuous DC High Voltage Holiday Detector
The high voltage method comes in two versions – Continuous DC and Pulsed DC. In this video, we’ll be introducing you to the Continuous DC method, which is used to test non-conductive coatings up to 7.5mm (300mils) thick on conductive substrates.

Testing Coating Porosity using an Elcometer Continuous DC High Voltage Holiday Detector
Setting the correct voltage is vital, as testing with a voltage that is too low could fail to break down the gap between the probe and substrate, missing flaws. While testing with a voltage that’s too high could break down and damage the coating, causing the unit to alarm when there are no flaws, while creating a flaw in the process. Testing with bright blue sparks is a clear sign the voltage is too high, and is probably damaging the coating.

Choosing the correct probe for your Elcometer High Voltage Holiday Detector
When it comes to testing the porosity of coatings using the high voltage or holiday detection method, regardless of whether you’re using a Continuous DC, or Pulsed DC detector, it’s important to choose the right probe for your application, so you can test thoroughly, efficiently, and ensure the most reliable results.
