📋 Scope / 适用范围 ai_extracted

This standard specifies the terms and definitions, product classification, requirements, test methods, inspection rules, marking, packaging, transportation, and storage of through-hole DC leakage current sensors (hereinafter referred to as leakage current sensors). This standard applies to current sensors that convert the leakage current between DC positive and negative feeders into DC voltage (current), where the output is a function of the corresponding input within the measurement range. This standard applies to leakage current sensors for measuring small DC currents of 1,000 mA and below.
