The calendar should reopen after release when information changes the safety or conformity position. Manufacturers must, when appropriate to the risks, perform sample testing, investigate complaints, keep registers of complaints, non-conforming equipment and recalls, and keep distributors informed of monitoring. Importers and distributors also have corrective-action and authority-notification duties when they believe equipment is not in conformity or presents a risk.
Market surveillance is not a scheduled annual formality. Under the LVD, authorities can require corrective action without delay, including bringing equipment into compliance, withdrawal, or recall within a reasonable period commensurate with the risk. Formal non-compliance, such as missing or incomplete technical documentation, incorrect CE marking, or missing manufacturer/importer information, can also lead to restrictions, withdrawal, or recall if it persists.
