NOTE 2 Bodies providing accreditation of test equipment may need to consider alternative requirements and/or calibration frequencies in order to cover the possibilities of National Health & safety, regulatory and legislative requirements. Advice is also given on recommendations for laboratory management (annex A), on the accuracy of measurement (annex B) and on the rounding of values for reported results (annex C). 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments applies). EN 932-5, Tests for general properties of aggregates — Part 5: Common equipment and calibration EN 61010-2-020, Safety requirements for electrical equipment for measurement, control and laboratory use — Part 2-020: Particular requirements for laboratory centrifuges (IEC 61010-2-020, modified) EN ISO 376, Metallic materials - Calibration of force-proving instruments used for the verification of uniaxial testing machines (ISO 376:1999) ISO 48, Rubber, vulcanised or thermoplastic — Determination of hardness (hardness between 10 IRHD and 100 IRHD) ISO 4662, Rubber — Determination of rebound resilience of vulcanizates ISO 7619, Rubber — Determination of indentation hardness by means of pocket hardness meters ISO 11095, Linear calibration using reference materials 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 calibrating set of operations that establish, under specified conditions, the relationship between values of quantities indicated by a measuring instrument or measuring system, or values represented by a material measure or a reference material, and the corresponding values realised by standards NOTE See ISO 10012. 3.2 checking operation of assuring either: SIST EN 12697-38:2005

that the results of measurements of a property (such as length, mass, temperature or time) at selected values made by an item, or a set of items, of equipment has not deviated from that which was measured when the equipment was last calibrated within a pre-defined tolerance; or —
that a property (such as hardness) of an item, or a set of items, of equipment complies with the relevant requirements for that equipment 3.3 reference instrument item of equipment that is used to calibrate other items of equipment that are to be used to perform tests NOTE A reference instrument should not be used to perform a test. 3.4 reference document item with a property (such as mass or length) whose known value is traceable to national standards and is used in the calibration of items of equipment that is to be used to perform tests NOTE A reference document should not be used to perform a test. 3.5 accuracy (of a measurement) (see Figure 1) difference between the measurement and the real or target value. Normally, the accuracy consists of two items: accuracy
= random error or precision +
systematic error or bias (trueness) NOTE 1 The accuracy of measurement is important because there is uncertainty in any measurement of physical properties. This uncertainty results from variations between two measurements of nominally identical samples and can result from various reasons including: —
differences in the composition of the samples tested; —
differences in the dimensions and shape of the samples tested; —
differences in equipment (dimensions, stiffness of moving parts, etc) used to carry out the tests; —
the precise procedure that the test is carried out (often due to different layout of equipment within different laboratories); —
the physical strength (in terms of the time to press buttons or speed in lifting items), speed of reactions and predilections of the operatives; and —
the precise environmental conditions prevalent during the test. These differences can be so minor that it is impractical to specify them within a test procedure, but they still combine to produce noticeable differences. NOTE 2 There is a distinction between “readability” and “accuracy”.
If equipment can be accurately read to 1 unit, then the random error in the value of the reading cannot be less than ± 0,5 units, that is 1 unit. There can also be random errors in the measurement method. Therefore, the accuracy of equipment, that is the total random error plus any bias, can never be closer than its readability and will usually be in excess of that. However, equipment cannot be calibrated to better than the readability, so that the accuracy is generally an order of magnitude greater than the readability and should always be at least twice the readability. 3.6 standard deviation (of a measurement) (see Figure 1) quantitative statistical expression of the precision of a measurement NOTE 1 There does not have to be a relation between precision and accuracy. A measurement can be precise and not accurate (in which case the bias is large). SIST EN 12697-38:2005

NOTE 2 A small confidence interval characterises a confident measurement method. The associated standard deviation of the measurement will be small.
