The work of preparing International Standards is normal

9、ly 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 and non-governmental, in liaison with ISO, also take part in the

10、 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 described in the ISO/IEC Directives, Part 1. In particular the

11、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 to the possibility that some of the elements of this docume

The report is intended to assist in hazard appreciation, risk asse

It is also intended to assist medical professionals in their care of welders and others exposed to welding fume. The constituent components of particular consumables and the fume ar

19、Report provides guidance, based on the experiences of experts, on the components of fume emitted from a range of arc welding processes and consumable types. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its

20、application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

21、and definitions given in ISO/TR 25901 apply. 4 Background Arc welding processes emit fume. This is a complex, dynamic mixture of particulates derived mainly from the welding consumable but also the metal and any coatings and contaminants present. Most of the particles are in the respirable range whi

22、ch means that they can penetrate to the innermost area of the lung where they have the greatest potential to do harm. Many particles contain metal compounds, often as complex oxides and sometimes within a core surrounded by a shell. Some of the components of the fume are at least potentially biologi

23、cally active. It is essential to be aware of these components when undertaking health and safety risk assessments of welding processes. Table 1 1)provides a general awareness to those responsible for making assessments or for the health care of welders and those who work with them. It identifies the

24、 principal and key components likely to be contained within the fume from a range of welding processes and consumable types. In this context, a principal component 2)is a component that is of some occupational hygiene significance while the key component 3)is the one that has the greatest occupation

25、al hygiene significance and therefore requires the most stringent control measures to ensure that a welder is not exposed to an excessive level of the substance concerned, i.e. it is the component whose limit value is exceeded at the lowest welding fume concentration. 1) This table is derived from t

26、hat shown in ISO 15011-4. 2) A principal component is a component of occupational hygiene significance. 3) Key components have the greatest occupational hygiene significance and therefore require the most stringent control measures to ensure that a welder is not exposed to an excessive level of the

27、substance(s) concerned, i.e. a component whose limit value is exceeded at the lowest welding fume concentration.
