Quality Control (QC) is the process of ensuring products meet specified standards through systematic measurement and inspection.
Quality Control involves the examination of a manufacturing process to verify that product specifications and performance criteria are consistently met. It is crucial for decreasing the variability in production and ensuring compliance with industry standards. Effective QC processes include regular inspections, testing of sample products, and utilizing statistical methods to monitor output quality.
In the automotive industry, Quality Control is implemented by measuring the dimensional accuracy of engine components to within ±0.02 mm (±0.0008 in).
This practice is commonly used in automotive manufacturing plants to ensure that parts such as pistons and bearings fit precisely, which is critical for engine efficiency and longevity.
In the pharmaceutical industry, Quality Control is applied through the chemical analysis of drug batches to ensure active ingredient concentration is within 95-105% of the specified target.
Such QC processes are standard in laboratories during the production of pharmaceuticals, where active ingredients must meet strict potency requirements for safety and efficacy.
