The work of preparing International Standards is normally carried out through ISO technic

22、al 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 work. ISO collaborates closely wi

23、th 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 different approval criteria needed

24、 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 document may be the subject of patent

25、 rights. ISO shall not be held responsible for identifying any or all such patent rights.

This document was prepared by ISO Technical Committee ISO/TC 146, Air quality, Subcommittee SC 1, Stationary source emissions. This third edition cancels and

28、 replaces the second edition (ISO 9096:2003), of which it constitutes a minor revision. It also incorporates the Technical Corrigendum ISO 9096:2003/Cor.1:2006. The changes compared to the previous edition are as follows: Table 3: in the row entitled “Isokinetic criteria (average measurement uncerta

29、inty)” the value “10 %” has been replaced by “ 5 15 % ” (according to ISO 9096:2003/Cor.1:2006). Formula (11): the percent symbol has been added twice. Formula (13): the percent symbol has been added twice. Figure A.2: 0,2. Formula (B.6): the parentheses have been removed. Formula (B.7): the formula

This level of accuracy is achieved by: a) exercising extreme care in weighing, in accordance with the procedures of thi

38、 matter (dust) concentration in waste gases of concentrations from 20 mg/m 3to 1 000 mg/m 3under standard conditions. This document is applicable to the calibration of automated monitoring systems (AMS). If the emission gas contains unstable, reactive or semi-volatile substances, the measurement wil

39、l depend on the filtration temperature. In-stack methods can be more applicable than out-stack methods for the calibration of automated monitoring systems. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requireme

43、ll the compounds that may be collected by filtration under specified conditions after representative sampling of the gas to be analysed, and which remain upstream of the filter and on the filter after drying under specified conditions, are considered to be dust (or particulate matter). However, for

44、the purposes of some national standards, the definition of particulate matter can extend to condensibles or reaction products collected under specified conditions (e.g. temperatures lower than the flue gas temperature). Note 2 to entry: This method restricts the definition of particulate matter to t

45、hat material collected in the sampling system on and before a filter, under specified temperature conditions.
