低压电器产品IEC和UL通用标准的差异比较

Comparison of the General Standards of IEC and UL for Low-Voltage Electrical Apparatus Products

我国的低压电器正大批量出口到欧美各国,出口产品需要符合IEC、UL等标准或获得相关认证才能在海外市场销售。在检验检疫的日常检验监管中发现,低压电器生产企业对UL和IEC标准之间的差异了解甚少,这样容易给出口产品和企业带来风险。分析了低压电器IEC和UL标准间的一些差异所在,如标准要求的泄漏电流测试仪器不一样,标准中II类和2类电器的定义和接地的术语标示不同,电动产品的额定值标示有所区别,塑料材料检测的试验方法和要求等差异。以此给广大电器生产企业一些建议和提示。

Our country＇s low-voltage electrical apparatuses are being exported in large batches to Europen and American countries, export products need to be in conformity with IEC, UL etc standards or obtain relevant accreditation to be sold on overseas market. It is found in daily inspection and supervision of inspection and quarantine that low-voltage electrical apparatuses production enterprises are in little knowledge of the differences between IEC and UL standards, thus it will bring risks for the export products and the enterprises. Analysis was made to some differences between low-voltage electrical apparatuses IEC and UL standards, such as different current leakage testers required by the standards, definitions and grounding technical term sign marks for kind II and kind 2 of electrical apparatuses in the standards are dif- ferent, electrical driven products rated value are with some distinctions and differences between plastic material test method and requirements etc, therefor to give broad electrical apparatuses production enterprises some suggestions and prompts.
