Quality Control (QC)
Definition - What does Quality Control (QC) mean?
Quality control (QC) refers to an industrial maintenance process that involves the thorough examination of all contributing factors to the final grade of a finished product. Industrial metal structures such as tanks and pipelines are often examined using quality control practices to ensure they are free of corrosion.
Corrosionpedia explains Quality Control (QC)
Quality control is an inspection method that is performed in strict alliance to published specification and standard guidelines. It is comprised of various techniques such as:
- Failure and fracture testing
- Alliance material sampling
- Statistical process control
- Analytical quality control
Quality control techniques are often performed by a team of professional inspectors who use specific measurement instruments. Without quality control techniques, a company would often be left in a position of using a given piece of equipment or material to the end of its useful life. Depending on the material application, this could have catastrophic consequences. For example, a tank containing H2S may catastrophically fail as pose fire risk and health hazards to surrounding personnel.
Furthermore, ASTM's quality control standards provide the mathematical statistical and empirical procedures that may be used in the evaluation of collected samples.
