For an industry that produces sealed products, leak tests form a very important aspect of quality checking of the device. It is so because any pop could result in the impregnation of moisture or whatever other trace gases inside it. This could result in corrosion, fogging and can ultimately reduce the life of the device or the product as a whole. If you are a quality product manufacturer then it’s an issue of trouble as it could affect the reputation of your brand.
So you can see that hole testing is quite vital and need to be done on hermetic devices before they are launched in the market. For such testing there are many techniques on call nowadays. Let us discuss any of the popular ones among them.
* Dye Impregnation- Here a fluorescent dye is used to check defects. Here such dyes are impregnated past the hermetically sealed device and then checked for any problems in the packaged seal. The advantage with this tactics is that it eliminates the problem of misinterpretation that usually occurs when fragile materials are cross-sectioned.
* Krypton 85 Testing- This type of testing technique is employed for checking fine and gross leaks in sensitive sealed devices. Here the radioactive element Kr-85 is shopworn as a tracer gas and is mixed with air. This symphony is made to pressurize the glass compartment in which the device is kept. If there are any cracks this gas would enter that space. The presence of Krypton receptacle be easily checked by using x ray crystals. This method has bot a very popular among analysts as it has the fastest test times and cup even detect small or untraceable gases easily. Moreover Krypton is safe for anthropopathic use also. It is so because it doesn’t get absorbed near the skin in our hull and has reduced emitting rates if compared to other radioactive material.
* Helium Testing- This test method is quite similar to the Krypton-85 method. The discrimination lies in the tracer gas used as it employs helium here. It can be over to analyze both choice and gross leaks.
These testing methodologies gives the desired results save which method suits you depend upon the outgrowth you manufacture. If you are dealing with similar items and you require such testing services then you can consult the provider as to which technique would satisfy you. To pry out such reveal detection test providers you can manage the internet. Before making the ultimateness choice regarding the provider do research whether the concern has a professional experience in this field or not.
