The IEC works close co-operation with many international organizations, including the International Organization for Standardization (ISO), which responsible for international standards non-electrical fields. Then, after that first step, unify the rules European Standards that are published national standards every European country. stronger rule for publishing applies European Standards so that now pressure made European Community publish almost exclusively European Standards. case installation rules, that necessary first bring the national rules closer to one another the basis Harmonization Documents. The Czech Republic member IEC and its membership the continuation the membership the previous Czechoslovak Republic since 1919. The development regional standardization organizations Europe has long history, beginning with the year 1926, when the IFK (Installation Fragen Kommission Installations Tasks Committee) was founded. Nowadays, this commission merged with IEC under the abbreviation IECEE after American, Japanese, and other laboratories joined this originally European organization. European Standards (EN) and Harmonization Documents (HD) are either endorsed or published national standards. Nevertheless, the rules published CEE are function till now because they lay the basis for many IEC standards well for European Harmonization Documents serving for the unification standards European countries within the framework CENELEC. CENELEC The European Committee for Electrotechnical Standardization (the abbreviation from the French name Comité Européen Normalisation Électrotechnique) - was founded 1973. The main purpose CENELEC remove any differences technical nature among national standards CENELEC member committees among national measures applied the certification conformity which may give rise trade barriers. . Nevertheless, there are fields where national traditions European countries are so strong, e. In some geographical regions, regional standardization organizations have developed. The Czech Republic member CENELEC since 1997 (its membership followed period its affiliation CENELEC). CENELEC consists National Electrotechnical Committees West European countries.g. The activity the committee continued after World War Two under the new name and abbreviation: International Commission Rules for the Approval Electrical Equipment - CEE.BASIC ELECTROTECHNICAL STANDARDS 14 energy. That was the committee European electrical testing laboratories, who prepared safety rules for electrical household appliances and installation devices well as testing rules. The IEC standards are prepared more than 200 specialized committees and are adopted and published the consensus National Committees
