Definitions Prepared by Chattanooga State

2
What is NDT?

• NDT stands for NonDestructive Testing
• Definition the use of noninvasive techniques to
  determine the integrity of a material, component
  or structure
• Or, testing that does not impair the future
  usefulness of a part
• Sometimes referred to as NDE, for NonDestructive
  Evaluation (or Examination)

3
Some Uses of NDT

• NDT test methods may be used to determine
• the size, shape, or orientation of a flaw (such
  as a crack or porosity)
• the thickness of a material or coating
• the hardness of a material
• the material composition (example, the carbon
  content in steel)
• a materials electrical conductivity

4
Who Uses NDT?

• NDT plays a vital role in assuring the safe
  operation of equipment and systems
• Industries that utilize NDT
• Airline and Aerospace
• Automotive and Railroad
• Construction
• Hydroelectric, Fossil, and Nuclear Power
• Textile and Manufacturing
• Chemical and Petrochemical

5
What is QA?

• QA stands for Quality Assurance
• Definition all the planned and systematic
  activities implemented within the quality system,
  and demonstrated as needed, to provide adequate
  confidence that an entity will fulfill
  requirements for quality
• Typically a program established by a company to
  develop procedures to follow to assure that
  standards of quality are being met

6
What is QC?

• QC stands for Quality Control
• Definition operational techniques and
  activities that are used to fulfill requirements
  for quality
• The actual testing of products to uncover defects
  or to ensure a product meets design
  specifications
• NDT is a subset of QC

7
Some Uses of QA/QC

• Technicians may perform quality audits, determine
  the root cause for a failure, or perform quality
  control testing according to written procedures
• QC technicians may be certified as
• Mechanical inspectors (pumps, valves, hangers)
• Civil inspectors (soil, concrete, structural
  steel)
• Electrical and IC inspectors (conduit, cable,
  instrumentation)
• Welding inspectors

8
Who Uses QA/QC?

• QA/QC technicians are needed in a wide variety of
  industries
• Some industries that utilize QA/QC
• Airline and Aerospace
• Construction
• Hydroelectric, Fossil, and Nuclear Power
• Logistics and Supply
• Medical and Pharmaceutical
• Textile and Manufacturing
• Chemical and Petrochemical
