How To Leak Test in The Consumer Products Market


Leak testing is an important part of the manufacturing process for many consumer products, as it helps to ensure the safety, performance, and reliability of the products. Some examples of consumer products that may be subject to leak testing include:



Many household appliances, such as refrigerators, washing machines, and water heaters, contain gas or water systems that must be leak-free in order to operate safely and efficiently.




Leak testing is often used to ensure that packaging, such as food containers or bottles, does not allow the contents to leak out.

Outdoor equipment

Leak testing is important for products such as gas grills and portable propane tanks, which may be used in outdoor settings and may pose a safety risk if they leak.

Personal care products

Leak testing is often used to ensure the integrity of containers for personal care products, such as shampoo or lotion to prevent leaks and spills.


Electronics such as smartphones, or watches are built to be leakproof. IP67 and Hermetic property leak tests must be done to ensure all products are leakproof. Adlema EP60 Leak testing apparatus can be used along with Adlema BT4000 Series Leak Testers in the manufacturing line.

Overall, leak testing helps to ensure that consumer products are safe, reliable, and of high quality. It is an important part of the manufacturing process and helps to protect consumers and the environment.



There are several methods that can be used to leak test consumer products in the manufacturing process, including:


Bubble test: This method involves introducing a gas or liquid into the product and then looking for the presence of bubbles, which can indicate a leak. However, bubble tests are not liable when it comes to manufacturing lines. By nature, It is depended on the operators’ ability to see bubbles that come out of the product. Depending on the leak rate that needs to be catched, the frequency of the bubbles may be down to 1 per 10 seconds. Of course in the applications that need to be more precise such as heat exchangers seeing bubbles is practically impossible. Thus other methods can be preferred instead of bubble tests such as differential pressure decay leak testing, mass flow leak testing, or helium mass spectrometer leak testing.


Pressure test: In this method, the product is pressurized with a gas or liquid and then checked for any changes in pressure, which can indicate a leak. By using differential leak testers pressure changes as small as 0.1Pa can be measured.  Adlema BT4000 Series Leak Testers are also a good fit for manufacturing lines. Able to work without an operator, using data analyzing tools, controlling automation systems, and modular systems such as Inkjet printers makes it a perfect candidate for manufacturing lines.


Vacuum test: This method involves applying a vacuum to the product and then checking for any changes in pressure, which can indicate a leak. A vacuum test is a version of a pressure test. Vacuum-0 Bars is a pressure option for Adlema BT4000 Series Leak testers.


Mass flow test: In this method, the flow rate of a gas or liquid through the product is measured and compared to a known standard. If the flow rate is not as expected, it may indicate a leak. While Pressure Tests are much more precise in volumes smaller than 20L, as the volume increases accuracy drops. However, by the method mass flow leak testers become advantageous in bigger volumes.


Helium mass spectrometer test: This method involves introducing a small amount of helium into the product and then using a mass spectrometer to detect the presence of helium, which can indicate a leak.


The specific method used for leak testing will depend on the product and the type of leak that is being tested for. It is important to carefully follow the manufacturer’s instructions and any relevant safety guidelines when performing leak testing. Reach us now to learn how to test your product.
