24、 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. International organizations, gover
25、nmental 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 the rules given in the ISO/IEC D
26、irectives, 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 by at least 75 % of the member
27、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.

EN ISO 9169:2006vIntroduction In this International Standard, automatic air quality measuring systems are considered as black boxes
29、 operated according to specified procedures as described in the terms of reference given by the client to the laboratory performing the tests aiming at determining performance characteristics selected by the client for each automatic measuring system. This International Standard specifies definition
30、s and methods to determine performance characteristics of automatic air quality measuring systems. This is done for most performance characteristics under steady laboratory conditions so as to have available data on clearly defined characteristics, based on specified conditions that can be adjusted
31、and maintained in laboratory. This is also done under field conditions for a few performance characteristics for which field testing provide relevant additional information. EN ISO 9169:2006blank1Air quality Definition and determination of performance characteristics of an automatic measuring system
32、 1 Scope This International Standard provides definitions and specifies methods to determine performance characteristics of an identified automatic air quality measuring system. Tests are carried out under stable laboratory conditions or field conditions. The automatic measuring system is considered
33、 as a black box operated according to specified procedures. This International Standard applies to measuring systems for which the following information is available: a description of the automatic measuring system providing the result of measurement in the physical unit of the measurand; operating
34、procedures of the automatic measuring system including, where appropriate, the procedures of routine adjustment, routine verification and calibration; terms of reference for the test program specifying the client requirements and test conditions. This International Standard applies to measuring syst
35、ems for which it is possible to apply several reference materials with accepted values with known uncertainty for the measurand, within the range of application. This International Standard does not specify the number of automatic measuring systems to be tested. NOTE 1 The number of automatic measur
36、ing systems is specified by the client in the terms of reference. NOTE 2 The list of performance characteristics in this document is limited. Additional performance characteristics can be specified by the client in the terms of reference, if appropriate. 2 Terms and definitions For the purpose of th
37、is document, the following terms and definitions apply. Definitions taken from VIM1are generally kept identical. Some definitions have been adapted from VIM to take into account the specific wordings of the present International Standard. 2.1 General terms 2.1.1 measuring system complete set of meas
38、uring instruments and other equipment with operating procedures to carry out specified air quality measurements NOTE 1 Adapted from VIM:1993, 4.5. NOTE 2 In general, a measuring system encompasses the different steps of the measurement process, such as taking the sample, the analytical quantificatio
39、n, etc. EN ISO 9169:20062 2.1.2 automatic measuring system AMS measuring system interacting with the air under investigation, returning an output signal proportional to the physical unit of the measurand in unattended operation NOTE The air under investigation includes, e.g. ambient air and emission
40、s. 2.1.3 continuous automatic measuring system automatic measuring system providing a continuous signal upon continuous interaction with the air mass under investigation 2.1.4 discontinuous automatic measuring system automatic measuring system providing a series of discrete signals NOTE Each discret
41、e signal corresponds to the averaging time for field operation specified in the terms of reference. 2.1.5 adjustment automatic measuring system operation of bringing an automatic measuring system into a state of performance suitable for its use NOTE 1 Adapted from VIM:1993, 4.30. NOTE 2 Adjustment m
42、ay be automatic, semi-automatic or manual. 2.1.6 primary result of measurement result of measurement produced by an automatic measuring system measuring the measurand over the shortest period of time for which valid measurements can be obtained and used by the automatic measuring system to calculate
43、 the result of measurement over the specified averaging period for routine field operations of the automatic measurement system NOTE For continuous automatic measurement systems, primary results of measurement are typically obtained for time periods of 1 s to 100 s, while the typical averaging time
44、is 1 h in ambient air measurements and 30 min in emission measurements. For discontinuous automatic measuring systems, one primary measurement result is typically obtained for a cycle of a few minutes. 2.1.7 time interval for the primary measurement result shortest period of time for which valid mea
45、surements can be obtained and used by the automatic measuring system to calculate the measurement result over the specified averaging period during routine functioning of the automatic measurement system 2.1.8 averaging time minimum time interval equal to a stated multiple of the response time NOTE
46、See 6.3.1. 2.1.9 averaging time for field operation time interval used by the automatic measuring system to produce routine results of measurement under normal (or envisaged) field operations NOTE 1 Examples of averaging time for field operations are half an hour for emission measurements and one ho
47、ur for ambient air measurements. NOTE 2 The averaging time for field operation may be too long to be used during laboratory tests. Therefore, an averaging time for laboratory test (2.1.10) is defined and specified. EN ISO 9169:200632.1.10 averaging time for laboratory test time interval used for lab
48、oratory test and specified in such a way that the duration of the test is limited to minimize the possible drift effect during the test as well as the cost of the test; all conditions and influences may be considered as equal under steady laboratory conditions (e.g. insignificant drift effects); the
49、 number of primary results of measurement collected over the averaging time is equal to the number of primary results of measurement collected over the intended averaging time for routine field operations. NOTE See 6.4.1. 2.1.11 measurand particular quantity subject to measurement VIM:1993, 2.6 NOTE In the field of air quality, the measurand is, e.g. the mass concentration of particulate matter or SO2in air. 2.1.12 interferent interfering substance substance present in the air mass under investigation
