   European industrial developed national cable standards is more strict than IEC standards

Britain, Germany, France and other European countries are highly industrial developed.The cable standards are generally more strict than the IEC standard.Now these standards are integrated with each other to form an absolute authority of the standard system, the European standard.

   The European Cable Association is the European Electrical Manufacturers Association: CENELEC, which includes Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, West Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain , Sweden, Switzerland and the United Kingdom National Electrician Association.

    Members of CENELEC are obliged to implement the CEN / CENELEC International Agreement, which states that this European Standard shall be subject to national standards and shall not be subject to any changes. Once a European standard has been promulgated, all members must be notified at the national standard level within six months of the promulgation of the European Union, and the European standard is implemented at a national level within one year after the enactment of the European Union. And in the next five years to abolish the European standards in conflict with the original national standards.

   In addition, the European Electrotechnical Commission has also issued a coordination document with the same European standard, that is, HD documents. HD documents also replace the national standards of the Member States within the time limit specified above.

In fact, European countries often replace European standards with their European standards in a very short period of time, such as the European standard for cable briquette burning tests, EN50266, which was issued in 2001, but in Britain, Germany and other countries In 2003, the same national standard BS4066, DIN VDE0472-804 has been abolished.

   The European standard number is directly included in national national standards without any change, such as EN50306 in national standards such as BS EN50306, DIN EN5050306 and NF EN50306 in English, German and French. HD files are numbered separately.

The European standard also incorporates some of the IEC, ISO standards, such as IEC60811, its European standard number EN 60811, in the national standard number BS EN60811, NF EN 60811 and so on.
