Safety of household and similar electrical appliances; part 2: particular requirements for storage water heaters

This specification defines specific safety requirements for storage water heaters used in household and similar applications. It serves as a supplementary section to the general safety rules established for electric appliances, addressing particular risks associated with heating elements and pressure vessels found in these devices. The document outlines test methods, constructional details, and operational constraints designed to ensure user protection against hazards such as electric shock, overheating, and mechanical failure. Detailed provisions cover electrical connections, temperature controls, and pressure relief mechanisms essential for safe operation. It also specifies requirements for labeling, durability, and performance under normal and abnormal conditions. The scope extends to various designs utilizing resistive heating within insulated tanks intended for domestic hot water supply. Compliance with these guidelines ensures that the appliance maintains structural integrity and electrical safety throughout its intended service life. The text addresses both new and existing technology used in the manufacturing of such heating systems without limiting the application to a specific brand or manufacturing process.
