FAQ

What is NDT?
 

Non-destructive testing (NDT) is a range of methods used to verify the integrity of parts, components, materials and structures without damaging them.

 

What does “non-destructive” mean?
 

Non-destructive testing (or inspection) does not destroy or in any way alter the parts, components, equipment or facilities tested. The materials and structures retain their full integrity, in contrast to destructive testing (breakage, stretching, wear, bending, etc.), in which the objects tested can no longer be used or are completely destroyed.

 

What types of NDT are available?
 

A wide range of non-destructive testing methods is available. The tests can be performed separately or sometimes in combination. The main methods include: x ray radiography, ultrasonic, dye penetrant, leak, eddy current and magnetic particle tests. The type of test to be applied depends on the type and nature of the components or structures to be analysed. We build on our experience going back nearly 50 years to provide virtually the full range of techniques currently in use.

 

What can NDT bring to my business?
 

Customers, particularly those working in “sensitive” industries, require NDT. They will only do business with you if you provide a guarantee that you comply with the applicable regulations concerning quality and reliability and hence safety.

 

What are the main industries in which NDT is used?
 

Most major industrial sectors, including the civilian and military aerospace, sheet metal fabrication, nuclear, chemical, shipbuilding, automotive, steel, pharmaceutical and food processing industries, use NDT to ensure the quality and reliability of their products. As a general rule, “sensitive” industries and industries producing high-cost or high-reliability components in which safety is a critical factor (nuclear, aerospace, etc.) employ NDT.

 

Is NDT applied only in heavy industry?
 

No, NDT is increasingly expanding into new (and sometimes surprising) sectors. For example, managers of sports facilities (skating rinks) use NDT to check the integrity of their cooling equipment. NDT is often used to check food container welds and jewellery metal plating thickness. The ionising radiation sources commonly used in NDT are also employed in the medical field (inoculation of mice used in cancer research, radiation of blood bags, etc.). NDT is also used in cultural (old paintings) and archaeological applications.

 

What is the advantage of outsourcing NDT?
 

As specialists, we give you the benefit of state-of-the-art facilities for performing all types of NDT. Most NDT equipment requires substantial investment. It would be economically unprofitable or prohibitively expensive for a company to acquire such equipment and obtain the specific certifications required to operate it.

 

Can I perform NDT myself?
 

An industrial company can carry out NDT, provided it has the required certifications and equipment. Actemium has long designed and produced ionising radiation (x ray and gamma ray) equipment in France. Its teams have put together a comprehensive range of solutions and services (engineering, sale, integration, maintenance) of x ray, gamma ray and ultrasound equipment based on existing products. They can help you define your need and supply the equipment to meet them.

 

How can I ensure the repair and maintenance of my NDT equipment?
 

Actemium maintains NDT equipment. Our teams are more particularly specialised in x ray, gamma ray and ultrasound equipment and more broadly in all facilities that produce ionising radiation.

 
Can you help me choose the right NDT solution for my business that meets my customers’ requirements and ensures regulatory compliance?
 

Our teams support you in making this choice. We propose the solution that best meets your expectations and those of your customers and help you to define your needs, comply with regulatory requirements and draw up a specification.

 
Do I need to have specific certification?
 

Yes, certification is required. In addition to “general” certification (ISO 9001, ISE 14001, OHSAS 18001, ISO 9712, etc.), we have the full range of certifications required for NDT and the qualifications that are specific to certain industrial environments and/or customers (aerospace, nuclear, petrochemicals, etc.): EN 9100, NADCAP, ISO 0712, EN 4179, COFREND, COSAC, CEFRI-E, CAS 1, MASE, etc. Our technicians are also individually certified to perform the tasks assigned to them.

 

Can you handle worldwide projects?
 

Our teams are fully mobile and we have NDT equipment that can be transported. There is therefore nothing to prevent us from supporting your projects all over the world.
