GB/T 14536.18-2006

This standard specifies the particular safety, performance, and testing requirements for float-type automatic water level controls used in household and similar electrical appliances. It applies to devices such as washing machines, water dispensers, humidifiers, and water tanks that rely on a floating mechanism to detect and regulate water levels. The standard ensures these controls operate reliably under normal and fault conditions, preventing overflow, dry running, or electrical hazards in domestic and light commercial environments.
