The HPC 420 Scheme is based on PAS 420. The development of this PAS was facilitated by BSI Standards Limited and was published on 31 October 2014. PAS 420 describes the requirements of an HPC Product Safety Management System and Prerequisite Programs to create the optimal conditions for manufacturing safe products.
HPC 420 adds quality management to the PAS 420 and provides extensive certification and Accreditation Bodies requirements. Furthermore, HPC 420 covers audit reporting, compliance, control, and integrity management infrastructure.
