Businesses providing technical testing and analysis examine materials, products, components, equipment and samples to assess their properties, performance, safety or condition. Their work may support manufacturing, construction, engineering, environmental monitoring, product development and quality control. Testing is carried out using measurement instruments, laboratory methods or controlled procedures, with results recorded and interpreted against specified requirements or recognised standards. Services can include chemical and physical analysis, materials testing, dimensional measurement, electrical and mechanical testing, product performance checks, failure investigation and non-destructive examination. Some providers also inspect equipment or buildings, collect samples, prepare test reports and advise on technical findings. The scope depends on the laboratory's facilities and areas of expertise.
