22、ndardization) 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 subject for which a technical committee has been established has the righ

23、t 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 (IEC) on all matters of electrotechnical standardization.The procedures

24、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 be noted. This document was drafted in accordance with the editorial rule

25、s 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 rights.

34、d biological examinations. Therefore, the goal of sampling should be to obtain a representative sample for the research question and to supply it to the laboratory in the correct manner. Errors caused by improper sampling, sample pre-treatment, transport and storage cannot be corrected.This part of

35、ISO 5667 specifies quality assurance and quality control procedures and provides additional guidance on sampling of the various types of water covered in the specific parts of ISO 5667.Quality control procedures are necessary for the collection of environmental water samples for the following reason

36、s:a) to monitor the effectiveness of sampling methodology;b) to demonstrate that the various stages of the sample collection process are adequately controlled and suited to the intended purpose, including adequate control over sources of error such as sample contamination, loss of determinand and sa

37、mple instability. To achieve this, quality control procedures should provide a means of detecting sampling error, and hence a means of rejecting invalid or misleading data resulting from the sampling process;c) to quantify and control the sources of error which arise in sampling. Quantification give

38、s a guide to the significance that sampling plays in the overall accuracy of data; andd) to provide information on suitably abbreviated quality assurance procedures that might be used for rapid sampling operations such as pollution incidents or groundwater investigations.This part of ISO 5667 is one

39、 of a group of International Standards dealing with the sampling of waters. It should be read in conjunction with the other parts of ISO 5667 and in particular with parts 1 and 3.The general terminology is in accordance with that published.vi ISO 2014 All rights reservedBS EN ISO 5667-14:2016Water q

45、 to a set of test or measurement results, involves a combination of random components and a common systematic error or bias component.Note 3 to entry: Accuracy refers to a combination of trueness and precision.SOURCE: ISO 3534-2:2006, 3.3.13.2biasdifference between the expectation of the test result

46、s or measurement result and a true valueNote 1 to entry: Bias is the total systematic error as contrasted to random error. There may be one or more systematic error components contributing to the bias. A larger systematic difference from the true value is reflected by a larger bias value.INTERNATION

The error of indication is the: “

Less precision is reflected by a larger standard deviation.Note 3 to entry: Quantitative measures of precision depend critically on the stipulated conditions. Repeatabili
