Safety Testing

Among the various inspection procedures for home appliances, electrical safety testing is the most prone to being overlooked or falsified. This article breaks down the operational steps, pass/fail criteria, and common causes of failure for six safety tests—dielectric strength, grounding, leakage current, insulation resistance, temperature rise, and power—in accordance with the IEC 60335 and GB 4706 standards, and includes key points for on-site implementation.
