The IET Regulations take account of the technical intent of the CENELEC European Standards, which in turn are based on the lEC International Standards. 

At the European level, the national organizations from both the EU (European Union, formerly the EEC) and the EETA (European Free Trade Association) are grouped in the CEN (European Committee for Standardization) and its counterpart for the electrical industries CENELEC. The standards published by these two organizations have authority in all EU countries as well as the EFTA countries who have voted their approval, which means that these standards have replaced their corresponding national standards. 

Also, the electronic control-valve device s level of immunity to, and emission of, electromagnetic interference (EMI) can be an issue in the chemical-valve environment. EMI requirements for the control-valve devices are presently mandatory in the European Community but voluntary in the United States, Japan, and the rest of the world. International Electrotechnical Commission (lEC) SOI, Parts I through 4, Electromagnetic Compatibihty for Industrial Process Measurement and Control Equipment, defines tests and requirements for control-device immunity. Immunity and emission standards are addressed in CENELEC (European Committee for Electrotechnical Standardization) EN 50 081-1 1992, EN 50 081-2 1993, EN 50 082-1 1992, and prEN 50 082-2 1994.

Beyond perfonnance optimization, issues relative to packaging and the need for compliance with certain safety and electronics regulatory codes are cited as reasons for a customized solution. In the latter case, a systems approach is required, especially when attempting to meet the code or performance requirements for compliance with European Certification (CE) mark or electrical and fire safety codes such as National Eire Prevention Association (NFPA) and CENELEC (European Committee for Electrotechiucal Standardization). Off-the-shelf electronics may provide the necessary performance characteristics for generic applications, and their use eliminates large expenses related to product development, plus the associated time delays. Photonics-related components are solely addressed in this section because they are used to customize instruments for application-specific systems. 

European countries have to take note of The European Committee for Standardisation (CEN) which was founded in 1961 and comprises the national standards bodies of EC and EFTA plus some eastern European countries. CENELEC is the equivalent body in the electrical field. To many people, the concept of European standards, or any other national grouping, is an unnecessary complication, it being argued that there is no need for any activity in between ISO and the national bodies. However, the work of CEN assumes great commercial importance because EC countries are bound to adopt them to replace national standards and they can be used to demonstrate compliance with EC Directives.

As time passes, national standards for area classification have been superseded by international standards (IEC, International Electrotechnical Commission, Geneva/Switzerland, and EN, European Standard or European Norm, established by CENELEC, Comite Europeen de Normalisation Electrotechnique, Brussels/Belgium), which have been adopted as subsequent national standards. In the member countries of the European Community (EC), a joint area classification is defined by a directive (Directive 1999/92/EC of the European Parliament and of the Council, dated 1999-12-16).

In the course of the integration of European states and the removal of trade barriers, national standardization loses importance considerably. The majority of electrical standards comes into existence by international cooperation with IEC, International Electrotechnical Commission, Geneva/Switzerland. On the basis of IEC Standards many European Standards have been developed in the past. This work has been done by CENELEC, Comite Europeen de Normalisation Electrotechnique, Brussels/Belgium. European Standards or Norms (EN) often deviate from their IEC origins in their technical content. To avoid double action and to ensure a more effective standardization procedure, IEC and CENELEC are now working in closer cooperation. CENELEC is a private organization and does not act as an institution of the European Union at all. This fact indicates that European Standards need a legal act to come into force. Members of CENELEC are the national committees for standardization of the member states (not identical with the European Union).

If an apparatus has been designed, constructed and successfully type tested according to established standards (e.g. according to European Standards EN. .. drawn up by CENELEC), the compliance with the ESRs is assumed generally (the so-called assumption of conformity - to be completed - with the ESRs ).

The CEN deals with European Standards, which are then issued by national standards organizations. The equivalent of the CEN for electrical products is the CENELEC. 

A draft European Nebulizer Standard (30) has been submitted for formal approval to CEN (Comite Europeen de Normalisation European Committee for Standardization). CEN is responsible for European standardization in all fields except Electrotechnical (CENELEC) and Telecommunications (ETSl). Publication of the European Nebulizer Standard is expected during 2001. Included within the European standard are detailed descriptions of two test methods for (1) assessing nebulizer aerosol output inhaled using breath simulation similar to that described previously and (2) assessing nebulized aerosol droplet size using low-flow cascade impaction. Because this standard is expected to be adopted throughout Europe (and possibly more widely), a summary of its contents may be useful to readers.
