ISO 17025 accreditation in Johannesburg at a glance
Construction clients in Johannesburg want to know that the concrete was tested by someone competent. With the development agency delivering bridges, precincts and bus rapid transit infrastructure and the property company building new municipal office precincts, laboratories that test materials and calibrate instruments are part of the delivery chain. ISO/IEC 17025 defines what makes such a laboratory competent: impartiality, trained staff, validated methods, traceable calibration, measurement uncertainty, data control and proof that results are valid. Sterling's Johannesburg office helps testing and calibration laboratories build the system, choose a realistic scope and rehearse the accreditation assessment before it begins, with Effivity and Sterling Academy included.

ISO 17025 in Johannesburg: questions clients ask
Which Johannesburg laboratories gain most from ISO 17025 accreditation?
Laboratories that sell results to contractors, developers and manufacturers, such as materials, environmental and calibration laboratories, because clients and regulators weigh accredited reports more heavily. In-house laboratories can benefit when customers audit them. Scope should match the tests your clients actually order.
How narrow can a first accreditation scope be?
Very narrow if you wish: a handful of methods or one calibration range. Starting narrow shortens the route and builds experience with the assessment process, and the scope can be extended later. Choose the tests that drive most of your revenue or that clients explicitly demand.
