Initial sample inspection

The initial sample inspection (sampling) is part of quality management and contributes significantly to the quality assurance of series production. In order to meet the customer’s requirements, it is essential to carry out an initial sample inspection. The product or components are checked for compliance with their technical properties, customer requirements, function and quality. This can result in extensive technical documentation, which can be organized using appropriate testing software. In this way, the manufacturer provides proof that the ordered products or components meet the quality requirements. The initial sample is the first product or component that is produced for the first time by an employee under standard conditions. The initial sample is subject to an inspection after release (full inspection). The initial sample inspection is chosen for series production in order to prevent errors, to check the product for quality and condition and to document whether agreements between the supplier and customer are being adhered to. Initial sampling can be carried out using various recognized procedures. The most common basis of the initial sample procedure is the Production Part Approval Process (PPAP) according to IATF 16949, as well as the Production Process and Product Release (PPF). These procedures can be used to optimize the quality planning of the initial sample inspection for customers and suppliers.
