ASNT-certified nondestructive testing experts

Our NDT inspectors are certified to American Society of Nondestructive Testing (ASNT) Level III and Level II. STANDARD & CODE INSPECTION QUALITY COMPANY  operates full-service NDT labs that utilize a variety of advanced equipment capable of performing quality inspections for virtually any form of ferrous material, component, or assembly, both in the laboratory and in the field.

What is nondestructive inspection?

Nondestructive evaluation covers a wide group of analysis techniques used to evaluate the properties of a material, part, product, weld, or system without causing damage. The terms Nondestructive examination (NDE), Nondestructive inspection (NDI), and Nondestructive evaluation (NDE) are also commonly used to describe this technology. 

NDT does not damage or permanently alter the article being inspected, which makes it a valuable technique that can save both money and time in product evaluation, troubleshooting, and research. Common NDT methods include ultrasonic or UT, magnetic-particle or MT, liquid penetrant or PT, radiographic inspection or RT, visual inspection or VT, and eddy-current testing. NDT is a commonly-used tool in forensic engineering, mechanical engineering, electrical engineering, civil engineering, systems engineering, aerospace and aeronautical engineering, and medical applications.

More information on NDT test methods and standards

• Radiography or RT: Using radioactive isotope (x-rays or gamma rays) a film is created, which we process in our laboratory or mobile darkroom. The results show defects which might otherwise be invisible. A vast array of material can be examined this efficient and reliable way—ranging from tiny electronic components to 20' freestanding concrete slabs. 
• Magnetic Particle or MT: For ferromagnetic materials such as castings, weldments, turbine components, forgings, and machined or stamped parts, this is one of the most sensitive nondestructive examinations. The sample is magnetized, and iron filings are applied, which adhere to any breaks in the magnetic field. Defects too small to be visible can be further examined with fluorescent inspection. 
• Liquid Penetrant or Dye Penetrant Inspection: STANDARD & CODE INSPECTION QUALITY COMPANY  scientists and technicians apply dye to a sample and then examine it visually or under fluorescent light to locate defects. This is a quick, economical NDT test method and easily set up in the field with our portable equipment. 
• Ultrasonic Inspection or UT:  With this method, NDT inspectors only need access to one side of a material. A transducer sends the ultrasound through the sample and the inner wall of a defect surface will send the wave bouncing back. Ultrasonic testing can also measure thickness, detect corrosion, and examine groove welds, and it’s also very portable and efficient. 
• Visual Inspection or VT: STANDARD & CODE INSPECTION QUALITY COMPANY  Visual Inspectors receive specialized training to employ a number of high-tech devices, including a Charge-Coupled Device (an advanced imaging and color chip system) and a joystick-driven 50-foot long Steer Probe for very tight access, as well as training on advanced computer programs that accurately measure defects, voids, pits, corrosion, and wear, and store this information on a variety of media. 
• Positive Material Identification or PMI: Positive Material Identification (PMI) is the identification and analysis of various metal alloys by their chemical composition through nondestructive methods. PMI can be conducted on-site or in the laboratory.
