The clarification and update of testing protocols, particularly in relation to moisture resistance, fire hazards, and electric strength testing, reflect an increased emphasis on practical applicability and safety in real-world scenarios. Moreover, the adjustments to touch current and voltage requirements, along with the incorporation of reduced touch voltages for interrupted DC voltage applications and PWM, demonstrate the standard’s responsiveness to current technological trends and safety challenges. The introduction of specific provisions for PELV applications showcases the standard’s relevance in today’s diversified market of electrical controlgear, adapting necessary guidelines as needed. With the incorporation of new annexes-specifically Annex N on touch current measurement and Annex O on document reorganization-this standard further enhances its usability by providing essential clarifications. The update of normative references, particularly concerning the transformer standards of IEC 61558 and PCB testing corrections, underscores the commitment to aligning with existing safety regulations and best practices. In summary, SIST EN IEC 61347-1:2025 emerges as a robust and essential standard that not only enhances safety for users and manufacturers but also signifies a progressive step towards more reliable controlgear for electric light sources within the defined voltage range. Its comprehensive nature and thoughtful revisions ensure that it remains relevant in an ever-evolving industry landscape.
