This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by March 2003, and conflicting national standards shall be withdrawn at the latest by March According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. Endorsement notice The text of the International Standard ISO :2002 has been approved by CEN as a European Standard without any modifications.
6 Page 4 Provläsningsexemplar / Preview Introduction ISO 8655 addresses the needs of: suppliers, as a basis for quality control including, where appropriate, the issuance of supplier's declarations; test houses and other bodies, as a basis for independent certification; users of the equipment, to enable routine checking of accuracy. The tests specified should be carried out by trained personnel.
7 Page 5 Piston-operated volumetric apparatus Part 1: Terminology, general requirements and user recommendations 1 Scope This part of ISO 8655 specifies the general requirements for piston-operated volumetric apparatus. It is applicable to piston pipettes, piston burettes, dilutors and dispensers. It furthermore defines terms for the use of piston-operated volumetric apparatus and gives user recommendations. ISO 8655 is not applicable to medical products intended for use on human beings, e.g. for medical syringes. NOTE For metrological requirements, maximum permissible errors, requirements for marking and information to be provided for users for piston-operated volumetric apparatus, see ISO for piston pipettes, see ISO for piston burettes, see ISO for dilutors and see ISO for dispensers. Conformity testing (type evaluation) of piston-operated volumetric apparatus is given in ISO Alternative test methods such as photometric and titrimetric methods will be the subject of a future Part 7 to ISO For all other tests (e.g. quality assurance by the supplier, analytical and measuring equipment quality assurance by the user) see ISO or alternative test methods. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 8655 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.

NOTE 2 The maximum permissible errors of piston-operated volumetric apparatus are specified in ISO to ISO Conformity testing for observance of maximum permissible errors is performed gravimetrically in accordance with ISO systematic error piston-operated volumetric apparatus difference between the dispensed volume and the nominal volume or selected volume of the piston-operated volumetric apparatus NOTE 1 General definitions for systematic error are given in the VIM and ISO NOTE 2 For conformity testing in accordance with ISO , the systematic error is ascertained by taking the mean of 10 measurements random error piston-operated volumetric apparatus scatter of the dispensed volumes around the mean of the dispensed volumes NOTE 1 General definitions for random error are given in the VIM and ISO NOTE 2 For conformity testing in accordance with ISO , the random error is ascertained by taking the repeatability standard deviation of 10 measurements uncertainty of measurement volume dispensed by a piston-operated apparatus parameter, associated with the dispensed volume, that characterizes the dispersion of the volumes that could reasonably be attributed to the dispensed volume NOTE 1 Adapted from the VIM. NOTE 2 The uncertainty of measurement comprises portions of the systematic and random error of measurement. The calculation of the uncertainty of measurement can be performed with the equation given in annex B of ISO : nominal volume piston-operated volumetric apparatus volume specified by the manufacturer and used for identification and for indication of the measuring range NOTE For specific piston-operated volumetric apparatus such as variable-volume piston pipettes and multi-channel piston pipettes, this definition is further qualified in the applicable parts of ISO selected volume variable-volume volumetric apparatus volume set by the user, in order to dispense a volume chosen from the useful volume range (3.1.7) of a variable-volume piston-operated volumetric apparatus NOTE For a fixed-volume piston-operated volumetric apparatus, the selected volume is equal to the nominal volume.
