Quality Assurance and Quality Control

What is quality assurance and quality control (QA/QC)?

Quality assurance and quality control (QA/QC) are two different activities that are part of quality management. QA is focussed on the process used to measure and provide confidence that quality requirements will be fulfilled, thereby preventing defects. Examples of QA activities include the examination and coordination of production documents and manufacturing supervision. QC is the process that ensures that the quality requirements are indeed met by identifying and correcting defects. This includes the inspection of semi-finished products before and after processing.

Why is quality management important?

New build plant projects are always expected to be completed in a timely and cost-effective manner while complying with national and international regulations and requirements. Having a good quality management programme minimises defects and enables smooth transition through all phases of the project. In addition, ensuring the quality of structures, components, equipment and systems in a plant may improve its operability, availability, reliability, and maintainability throughout the rest of its lifetime.

TÜV SÜD ensures that your chemical processing plant is built to quality standards.

From the design stage, we ensure that your components are compliant with relevant standards and requirements. Our experts can conduct tests on components at your suppliers’ site and recommend any adjustments required during the manufacturing process to ensure that they can meet your specifications, timeline and budget. We also certify your components according to PED 2014/68 / EU, ensuring market access when required.

With our global multidisciplinary pool of experts which include welding engineers, welding technicians and inspectors experienced with the requirements of the chemical and pharmaceutical industries, we will be able to support you in over 1,000 locations worldwide.
