15、dies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental an
16、d non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are de
17、scribed in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn
18、 to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on th

Nebulizers are also used for diagnostic purposes using radioisotopes for lung challenge tes
23、ts. These drugs can be in the form of a solution, suspension or emulsion. Aerosol inhalation is the preferred route of administration for some drugs. Some drugs are intended for treatment of systemic diseases and other drugs are intended to treat respiratory diseases. To achieve the intended treatme
24、nt, aerosol particles have to be deposited in specific parts of the respiratory tract. Different size particles tend to deposit in different parts of the respiratory system; therefore, the performance profile and the intended use of the nebulizer have to be defined by the manufacturer and specified
25、in the accompanying documentation.This International Standard is based on Reference.29This International Standard was developed to cover “general purpose” nebulizers and is based on adult test parameters which are likely to be different than stated when testing for paediatric or infant patient popul
26、ations. It was specifically written to ensure that the results of the various tests declared by the manufacturer are meaningful to the users and buyers of nebulizers.The objectives of this International Standard are to ensure suitability of the nebulizers for the intended use as disclosed by the man
27、ufacturer, safety, particularly for electrically powered nebulizers, compatibility between the materials of the components and the dispensed liquid, and biocompatibility of the materials of the components that come into contact with the human body.Important changes were made to the original EN stand
28、ard in recognition of the advances in test devices such as lasers and low-flow impactors that allow manufacturers to use different test methods, provided these alternate methods are validated against the methods specified in this International Standard.Terms defined in this International Standard ar

32、s International Standard includes gas-powered nebulizers which can be powered by, e.g., compressors, pipeline systems, cylinders, etc., and electrically powered nebulizers e.g., spinning disc, ultrasonic, vibrating mesh (active and passive), and capillary devices or manually powered nebulizers.This
33、International Standard does not specify the minimum performance of nebulizing systems.*This International Standard does not apply to devices intended for nasal deposition.This International Standard does not apply to devices intended solely to provide humidification or hydration by providing water i
34、n aerosol form.NOTE ISO 8185 covers this.3*This International Standard does not apply to drug-specific nebulizers or their components (e.g., metered dose inhalers, metered liquid inhalers, dry powder inhalers).2 Normative referencesThe following documents, in whole or in part, are normatively refere
