leak testing is quickest for medium- and large-sized components, whilst mass extraction technology is faster than other air testing methods such as pressure decay. Cost is another crucial factor – and that’s where your equipment supplier has a key role to play. It’s imperative to look at the life-cycle costing of the test method and its overall suitability and not just the cost of acquiring the product. What are the other costs associated with the method? Where can this technology be applied elsewhere in the operation? Does it meet a short- or a meet changing needs? Sensitivity must be considered too. In applications
where high levels of sensitivity are required (e.g. medical products where leaks can cause a risk of contamination) or that have stringent water ingress applications, airbag activators, nuclear facilities, etc, the only option is helium leak detection. However, in most applications such as heat
exchangers, brake systems, welded assemblies, electronic enclosures, etc, both air or helium test methods can be used.
A combination of both types of test methods is generally only applied when the parts under test are high-cost items such as those found in the aerospace industry.
Choosing the right leak testing method is critically important and it all starts with your choice of equipment supplier. It must have an extremely high level of expertise and experience but it also needs to really understand the intricacies of your business, how it works and what your long-term goals are, so that it can recommend solutions that do more than just meet technical needs. One example of an expert in this in Western Australia that has a reputation for service delivery that goes beyond expectations.
