低压电器产品标准在国际上主要分为四大标准体系,分别为IEC标准体系、EN标准体系、北美标准体系和中国、日本标准,前者为国际标准体系,后三者为区域性标准体系。以区域性为主的标准体系形成主要是发达国家和地区,其余发展中国家和地区还未形成系统的标准体系,如东盟地区、中东地区、非洲地区等。我国低压电器涉及的出口国家与地区众多,主要包括欧盟、北美、中南美洲和亚洲。以下重点介绍欧、美、日等国家及地区低压电器相关标准,并与我国现行国家标准进行比较。
Low-voltage electrical product standards in the international community is divided into four major standard systems, namely IEC standard system, EN standard system, North American standard system and China, Japan standard, the former is the international standard system, the latter three as a regional standard system. The formation of a standard system dominated by the region is mainly developed countries and regions. The rest of the developing countries and regions have not formed a systematic standard system such as the ASEAN region, the Middle East, and Africa. China’s low-voltage electrical appliances involved in the export of many countries and regions, including the European Union, North America, Central and South America and Asia. The following highlights the relevant standards for low-voltage electrical appliances in Europe, the United States, Japan and other countries and regions and compares them with the current national standards in our country.
