Quality Assurance/Quality Control Program
Group Delta Quality Assurance Program is designed to provide the documentation needed to establish confidence that the testing or inspection function is being performed properly and consistently. Group Delta’s Quality Systems Manual includes internal and external audits of our program, and the results of our participation in sample reference programs. Our reports are reviewed and signed by a registered professional engineer after first undergoing a strict peer review process. This level of QA/QC provides our clients with peace of mind knowing that testing performed in our laboratories is done per stringent industry standards.
