NDT stands for Non-Destructive Testing, and it's also a vital part of quality control systems in the technology and science industry today. Fractional treatments means that it is able to use various systems that test various elements of the products to determine durability and quality. Another field that NDT is commonly used is in medicine. - Computed Radiography

A number of the methods used are:o Ultrasonic testing
o Radiographic
o magnetic-particle
o Remote visual inspection
o liquid penetrator

This is a very efficient and cost efficient way to look at the quality of the product or service and the durability of the specific compounds. This proves very valuable to companies because field, avoiding waste of materials and time when the product met the standard but was destroyed while testing. This is vital in troubleshooting and research and development.
However, even though NDT equipment can conserve a company lots of money they're extremely expensive to buy and incredibly difficult to operate. This may put the majority of companies off investing in their own NDT equipments and software.

To utilize NDT equipment you need to gain the mandatory qualifications to protect the gear itself and the workforce around it.

Those two points can drive a business to the decision to outsource their NDT to a different specialist company where they have the necessary equipment and expert staffing to execute the testing to the highest level.

Before outsourcing with a company, make sure you seek information it is vital that they have the essential qualifications and skills to handle the work that you are sending them. If you don't make this research then you are in danger of spending big money and possibly damaging all of that batch of products if the tests are not accomplished properly. This is particularly relevant if you are in the medical field using x-ray equipment on a possible broken bone (when the person that you are x-raying is unnecessarily hurt) then you could had a lawsuit to handle after as well as a bad reputation.

As one example of how NDT is used to spot a crack within a product that is invisible to the naked eye:
o A liquid penetrant is used all over the surface of the product, to ensure that any microscopic cracks are soaked in the liquid.
o Then the excess penetrant taken off the top of the product
o This leaves any penetrant that entered the crack still there
o Finally a developer is added, this will make the crack visible.

Because of this if the product is unfit for use then it may be scrapped or recycled, or maybe the product meets the high quality management standards then is can nonetheless be used as no damage will have occurred during the testing. - Computed Radiography
