22、:2013ISO 13137:2013(E)ForewordISO (the International Organization for Standardization) is 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

23、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 work. ISO collaborates closely with the International Electrotechnical Commission

24、 (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 different approval criteria needed for the different types of ISO documents should

25、be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2, www.iso.org/directives.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

26、 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 the ISO list of patent declarations received, www.iso.org/patents.Any trade name used in this document is information given for the convenience of user

27、s and does not constitute an endorsement.The committee responsible for this document is ISO/TC 146, Air quality, Subcommittee SC 2, Workplace atmospheres. ISO 2013 All rights reserved vBS EN ISO 13137:2013ISO 13137:2013(E)IntroductionMany different methods are used to determine the concentration of

28、chemical and biological agents in workplace air. Many of these methods involve the use of a pump and sampler connected by a flexible tube. Air is drawn through the sampler and chemical and biological agents are trapped, e.g. on a filter, sorbent tube or long-term detector tube, or in a gas washing b

29、ottle. In personal sampling, the pump and sampler are attached to the worker so as to collect chemical and biological agents in the breathing zone.The volume of air drawn by the pump during the sampling period is one of the quantities in the calculation of the concentration of the chemical and biolo

30、gical agents in air. Therefore, the volume of air sampled should be determined accurately and, in order to facilitate this, the flow rate should be maintained within acceptable limits throughout the sampling period. For particle size selective sampling, the short-term fluctuation of the flow rate sh

31、ould also be maintained within acceptable limits in order to ensure that the sampler exhibits the required collection characteristics.EN 4821specifies general performance criteria for methods for measuring the concentration of chemical and biological agents in workplace air. These performance criter

32、ia include maximum values of expanded uncertainty that are not to be exceeded under prescribed laboratory conditions. In addition, the performance criteria should also be met under a wider variety of environmental influences, representative of workplace conditions. The contribution of the sampling p

33、ump to measurement uncertainty should be kept to a minimum.This International Standard is intended to enable manufacturers and users of personal sampling pumps to adopt a consistent approach to, and provide a framework for, the assessment of the specified performance criteria. Manufacturers are urge

34、d to ensure that pumps meet the requirements laid down in this International Standard, including environmental influences which can be expected to affect performance.vi ISO 2013 All rights reservedBS EN ISO 13137:2013Workplace atmospheres Pumps for personal sampling of chemical and biological agents

35、 Requirements and test methods1 ScopeThis International Standard specifies performance requirements for battery powered pumps used for personal sampling of chemical and biological agents in workplace air. It also specifies test methods in order to determine the performance characteristics of such pu

36、mps under prescribed laboratory conditions.This International Standard is applicable to battery powered pumps having a nominal volume flow rate above 10 ml min1, as used with combinations of sampler and collection substrate for sampling of gases, vapours, dusts, fumes, mists and fibres.This Internat

37、ional Standard is primarily intended for flow-controlled pumps.2 Normative referencesThe following referenced documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
