21、 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 represented on that committee. Int
22、ernational organizations, governmental and 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. International Standards are drafted in accordance with t
23、he rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval
24、by at least 75 % of the member bodies casting a vote. Attention is drawn 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. ISO 10882-1 was prepared by Technical Committee

BS EN ISO 10882-1:2011ISO 10882-1:2011(E) ISO 2011 All rights reserved vIntroduction The health of workers in many industries is at risk through exposure by inhalation to airborne particles generated by welding and al
28、lied processes (welding fume) and other airborne particles generated by welding-related operations, e.g. grinding. Industrial hygienists and other public health professionals need to determine the effectiveness of measures taken to control workers exposure to these harmful substances and this is gen
29、erally achieved by making personal exposure measurements. This part of ISO 10882 specifies a sampling method for welding fume and airborne particles generated by welding-related operations for the purpose of making personal exposure measurements in the operators breathing zone. It is intended to be
30、of benefit to: agencies concerned with health and safety at work, industrial hygienists and other public health professionals, industrial users of welding and allied processes and their workers, and analytical laboratories. It has been assumed in the drafting of this part of ISO 10882 that the execu
31、tion of its provisions, and the interpretation of the results obtained, is entrusted to appropriately qualified and experienced people.

32、es Sampling of airborne particles and gases in the operators breathing zone Part 1: Sampling of airborne particles 1 Scope This part of ISO 10882 specifies a procedure for sampling airborne particles in the breathing zone of a person who performs welding and allied processes (the operator). It also
33、provides details of relevant standards that specify required characteristics, performance requirements and test methods for workplace air measurement, and augments guidance provided in EN 689 on assessment strategy and measurement strategy. This part of ISO 10882 also specifies a procedure for makin
34、g gravimetric measurements of personal exposure to airborne particles generated by welding and allied processes (welding fume) and other airborne particles generated by welding-related operations. Additionally, it provides references to suitable methods of chemical analysis, specified in other stand
35、ards, to determine personal exposure to specific chemical agents present in welding fume and other airborne particles generated by welding-related operations. The general background level of airborne particles in the workplace atmosphere influences personal exposure and therefore the role of fixed-p
36、oint sampling is also considered. 2 Normative references The following referenced documents are indispensable for the application of this document.

41、epted to be 30 cm in radius) extending in front of the human face, centred on the mid point of a line joining the ears. The base of the hemisphere is a plane through this line, the top of the head and the larynx. This technical description is not applicable when respiratory protective equipment is u

Limit values for gases and vapours are stated in terms independe

Limit values for airborne particles as well as mixtures of particles and vapours are given in mil
