The International Organisation for Standardisation (ISO) defines product certification as a process whereby a third party verifies and certifies in writing that an organisation's products, processes or services meet specific requirements and have the ability to consistently produce products that meet the requirements of a standard, through inspection and evaluation of the organisation's quality management system and sample type testing. After a product has been certified and issued with a certificate, a certification mark can be affixed to the product. This internationally recognised and effective form of product certification provides a shortcut for organisations to establish a good reputation and brand image and for customers and consumers to evaluate the quality of goods, while also acting as a passport for products to enter the international market and as an authoritative and effective safety certificate for products to enter the markets of different countries and regions.
