DIN EN 16479:2014-09EN 16479:2014 (E) 4 Introduction This European Standard is a product standard for

22、 automated sampling devices (samplers) for water and waste water. It defines general requirements, performance requirements, and procedures for the conformity testing of samplers. Samplers that are shown, by means of the tests, to conform with the specified requirements are considered to be fit for

23、purpose. However, this European Standard does not cover the installation and on-going use of samplers. The requirements of this European Standard are intended to be independent of measurement technology and applicable to all automated sampling devices. Water monitoring equipment is widely used for c

24、ompliance monitoring purposes under national and European regulations. This European standard supports the requirements of the following EU Directives: Industrial Emissions Directive (2010/75/EU) 6. Urban Waste Water Treatment Directive (UWWTD) (91/271/EEC and 98/15/EEC) 7. Water Framework Directive

25、 (2000/60/EC) 8. Marine Strategy Framework Directive (2008/56/EC) 9. DIN EN 16479:2014-09EN 16479:2014 (E) 5 1 Scope This European Standard defines general requirements, performance requirements and conformity test procedures for automated sampling devices (samplers) for water and waste water that:

26、sample water and waste water from non-pressurized (i. e. open to atmosphere) channels or vessels; sample over extended periods to collect discrete or composite samples based on time, event or flow proportional sampling. Specific sample integrity requirements are defined for samplers to be used for t

27、he collection of samples of final effluent or influent for the purpose of monitoring the performance of waste water treatment works, as required under the Urban Waste Water Treatment Directive (UWWTD). Samplers to be used for other industrial applications do not have to be assessed against these spe

28、cific sample integrity requirements. This European Standard does not cover the installation and on-going use of samplers. 2 Normative References The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

31、 waste water for subsequent analysis 3.2 bias estimate of a systematic measurement error Note 1 to entry: The systematic measurement error is a component of measurement error that in replicate measurements remains constant or varies in a predictable manner.

32、ied Note 1 to entry has been added. 3.3 composite sample two or more samples or sub-samples, mixed together in appropriate known proportions (either discretely or continuously), from which the average result of a desired requirement may be obtained Note 1 to entry: The proportions are usually based

33、on time or flow measurements.

36、r of measurement error measured quantity value minus a reference quantity value Note 1 to entry: The concept of “measurement error” can be used both: a) when there is a single reference quantity value to refer to, which occurs if a calibration is made by means of a measurement standard with a measur

37、ed quantity value having a negligible measurement uncertainty or if a conventional quantity value is given, in which case the measurement error is known, and b) if a measurand is supposed to be represented by a unique true quantity value or a set of true quantity values of negligible range, in which

38、 case the measurement error is not known. Note 2 to entry: Measurement error is not be confused with production error or mistake. SOURCE: ISO/IEC Guide 99:2007, 2.16 3.10 rated operating conditions minimum to maximum values of any environmental, fluid or electrical parameter within which the sampler

39、 is designed to operate without adjustment and with errors within performance limits 3.11 lift height vertical distance between the surface of the fluid being sampled and the highest point to which the sample is lifted Note 1 to entry: Sometimes called “sampling head” or “suction height”. DIN EN 164

40、79:2014-09EN 16479:2014 (E) 7 Note 2 to entry: The maximum lift height for samplers using vacuum pumps (e.g. pneumatic samplers and peristaltic samplers) is set to an atmospheric pressure of 1 000 mbar. At low atmospheric pressure the maximum lift height will be consequentially lower. 3.12 precision

41、 closeness of agreement between indications or measured quantity values obtained by replicate measurements on the same or similar objects under specified conditions Note 1 to entry: Measurement precision is usually expressed numerically by measures of imprecision, such as standard deviation, varianc

42、e, or coefficient of variation under specified conditions of measurement. Note 2 to entry: The “specified conditions” can be, for example, repeatability conditions of measurement, intermediate precision conditions of measurement, or reproducibility conditions of measurement (see ISO 5725-3:1994). No

43、te 3 to entry: Measurement precision is used to define measurement repeatability, intermediate measurement precision, and measurement reproducibility. Note 4 to entry: Sometimes “measurement precision” is erroneously used to mean measurement accuracy. SOURCE: ISO/IEC Guide 99:2007, 2.15 3.13 samplin

45、nts for samplers See 6.3 for details on verification by inspection. A sampler shall: a) have an unique designation that unambiguously identifies it (e.g. model, serial number); b) be designed (including its operating methodology) and constructed to ensure that the composition of the sample is, as fa

46、r as is practicable, not altered by the sampling procedure; It can be impracticable to prevent the loss of volatile substances during sampling with vacuum and peristaltic samplers. c) have a rated maximum lift height at which all of the performance requirements of this standard are fulfilled. The ra
