Here are some key Relay industry standards:

IEC 61810 (International Electrotechnical Commission): This standard provides guidelines for the performance and testing of electromechanical relays. It includes classifications, test conditions, and environmental requirements for relays used in different applications. UL 508 (Underwriters Laboratories): UL 508 applies to industrial control equipment, including relays. It outlines safety standards for relays that are part of control systems to prevent electrical hazards. ISO 9001 (International Organization for Standardization): While not specific to relays, ISO 9001 defines the quality management system standards that relay manufacturers should adhere to. This standard ensures consistent product quality, operational efficiency, and customer satisfaction.
