5 Different Types of Leak Detection Methods
In business, there are all kinds of products and packages that need to be sealed properly and work properly or it can damage or spoil these goods. Let’s face it, people are going to complain if they buy something that is faulty and you cannot really blame them.
After all, they are paying for something that is not up to par. All these packages need to pass the quality control tests or it really should not be placed for sale. This means looking for leaks and other kinds of issues. Leak detection equipment is essential in maintaining high standards and ensuring that all seals and seams are secure, so let’s take a closer look at leak detection equipment and methods.
1. Bubble Emission Test
The Bubble Emission test is a very efficient way to test packages that have some air or gas in the package. These packages are submerged in a leak detecting equipment that contains water and uses a vacuum to see if there are any bubbles. If there are, then the package is definitely faulty.
If you can tell where the problem is, then at least the necessary steps can be taken to rectify the problem. This is obviously important, but the main thing is that the leak detection equipment must visually show where the location of the damage is, otherwise the problem cannot be fixed and not all leak detection equipment can do this. That’s why it is important to use quality equipment when performing a Bubble Emission test.
2. The Dry Chamber Test
The Dry Chamber method is ideal for testing on packages that contain liquids and that do not contain any air or have much headspace. Milk is often tested this way. Packages are placed in the chamber and it is subjected to a vacuum. An absorbent material such as a paper towel is used and after the test, if the paper towel is moist, then the package is compromised.
3. Altitude Simulation Method
This is arguably one of the most important tests. This is to test packages and goods that will be doing some traveling at varying altitudes. The critical points for these packages is during takeoff and landing because they will be subjected to some pretty harsh conditions. This test also lets manufacturers as well as the various packaging industries know that the packages can stand the conditions they will be subjected to at high altitudes. These tests can be performed either in a dry or wet chamber.
4. Seal Integrity
Any package that is vacuum packed or sealed goes through the Seal Integrity test. It actually uses the Bubble Emission procedures but there is also a special attachment that is used in addition.
5. Gas Leak
Gas also has to be packaged and you certainly would not want a gas leak whatsoever. This is a method that requires a more thorough knowledge in its use.
Leak detection is used for many items and these include testing meats, seafood, pet food, medical and pharmaceutical products, snacks, coffee, cheese, confectionary and package manufacturers. Some of the tests can be done in less than a minute. When it comes to checking for leaks, you just cannot be too careful which is why it pays to use the best leak detection equipment.
