Annex VIII Part B requires an approved production quality system assessed by a notified body, plus surveillance audits and evidence checks for recycled content and, where applicable, carbon footprint data.
Use Module G for non-series batteries when Article 7 or 8 is in scope, or when the manufacturer chooses unit verification for all applicable requirements. Annex VIII Part C requires the manufacturer to make technical documentation available to a notified body, which carries out or has carried out the examinations, calculations, measurements, and tests and issues a certificate of conformity.
