25、s a worldwide federation of national standards bodies (ISO member bodies). 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 represe

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop

27、 this document and those intended for its further maintenance are described 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/IE

34、an be harmful to human health. Therefore, control of the fumes and gases generated is to be exercised to minimize worker exposure.The most effective method of control is to capture the fumes and gases close to their source before they enter a workers breathing zone or the general workplace environme

35、nt.Ventilation equipment used to capture the fumes and gases is to be fit for purpose because inefficient capture could result in high exposure and can be detrimental to workers health. It is important therefore that it adheres to defined manufacturing, materials and design requirements and gives wa

36、rning of malfunction.This part of ISO 15012 defines the general requirements that are necessary for ventilation equipment to maintain exposure to fumes at acceptable levels.This part of ISO 15012 is a type-B standard as stated in ISO 12100.This part of ISO 15012 is of relevance, in particular, for t

37、he following stakeholder groups representing the market players with regard to machinery safety: machine manufacturers (small, medium and large enterprises); health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.).Others can be affected by the level of mac

38、hinery safety achieved with the means of this part of ISO 15012 by the above-mentioned stakeholder groups: machine users/employers (small, medium and large enterprises); machine users/employees (e.g. trade unions, organizations for people with special needs); service providers, e.g. for maintenance

39、(small, medium and large enterprises); consumers (in case of machinery intended for use by consumers).The above-mentioned stakeholder groups have been given the possibility to participate at the drafting process of this part of ISO 15012.In addition, this part of ISO 15012 is intended for standardiz

40、ation bodies elaborating type-C standards.The requirements of this part of ISO 15012 can be supplemented or modified by a type-C standard.For machines which are covered by the scope of a type-C standard and which have been designed and built according to the requirements of that standard, the requir

41、ements of that type-C standard take precedence.
