1.1<\/b> The purpose of this part of ISO 5725 is to give some indications of the way in which accuracy data can be used in various practical situations by:<\/p>\n

    \n
  1. \n

    giving a standard method of calculating the repeatability limit, the reproducibility limit and other limits to be used in examining the test results obtained by a standard measurement method;<\/p>\n<\/li>\n

  2. \n

    providing a way of checking the acceptability of test results obtained under repeatability or reproducibility conditions;<\/p>\n<\/li>\n

  3. \n

    describing how to assess the stability of results within a laboratory over a period of time, and thus providing a method of \u201cquality control\u201d of the operations within that laboratory;<\/p>\n<\/li>\n

  4. \n

    describing how to assess whether a given laboratory is able to use a given standard measurement method in a satisfactory way;<\/p>\n<\/li>\n

  5. \n

    describing how to compare alternative measurement methods.<\/p>\n<\/li>\n<\/ol>\n

    1.2<\/b> This part of ISO 5725 is concerned exclusively with measurement methods which yield measurements on a continuous scale and give a single numerical figure as the result, although this single figure may be the outcome of a calculation from a set of observations.<\/p>\n

    1.3<\/b>It is assumed that the estimates of trueness and precision for the method have been obtained in accordance with parts 1 to 5 of ISO 5725.<\/p>\n

    1.4<\/b>Any additional information regarding the field of application will be given at the beginning of each particular application.<\/p>\n
