IQMS accredits inspection agencies to ISO/IEC Standard 17020. This accreditation process involves an assessment of the agencies competence for performing inspections and the consistency of their inspection activities. IQMS accredits agencies that perform inspections of materials, products, installations, processes or services.
An inspection is, most generally, an organized examination or formal evaluation exercise. In engineering activities inspection involves the measurements, tests, and gauges applied to certain characteristics in regard to an object or activity. The results are usually compared to specified requirements and standards for determining whether the item or activity is in line with these targets. Inspections are usually non-destructive.
In international trade several destination countries require Pre-shipment inspection. The importer instructs the shipper which inspection company should be used. The inspector makes pictures and a report to certify that the goods that are being shipped and produced are in accordance with the accompanying documents.

Some common methods are visual, microscopy, Liquid or dye penetrant inspection, magnetic-particle inspection, X-ray or radiographic testing, ultrasonic testing, eddy-current testing, acoustic emission testing, and thermographic inspection. In addition, many non-destructive inspections can be performed by a precision scale, or when in motion, a checkweigher. Stereo microscopes are often used for examining small products like circuit boards for product defects.
