ISO 8655-6:2002(E)
Foreword
ISO (the International Organization for Standardization) 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 right 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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this part of ISO 8655 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 8655-6 was prepared by Technical Committee ISO/TC 48, Laboratory glassware and
related apparatus, Subcommittee SC 1, Volumetric instruments.
ISO 8655 consists of the following parts, under the general title Piston-operated volumetric apparatus:
— Part 1: Terminology, general requirements and user recommendations
— Part 2: Piston pipettes
— Part 3: Piston burettes
— Part 4: Dilutors
— Part 5: Dispensers
— Part 6: Gravimetric methods for the determination of measurement error
The following part is under preparation:
— Part 7: Non-gravimetric methods for the determination of measurement error

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.

INTERNATIONAL STANDARD ISO 8655-6:2002(E)
Piston-operated volumetric apparatus —
Part 6:
Gravimetric methods for the determination of measurement error
1 Scope
This part of ISO 8655 specifies the reference method for conformity testing of piston-operated volumetric apparatus,
whereby errors of measurement are determined gravimetrically. The tests are applicable to complete systems
comprising the basic apparatus and all parts selected for use with the apparatus, disposable or reusable, involved in
the measurement by uptake (In) or delivery (Ex) process.
NOTE General requirements and definitions of terms of piston-operated volumetric apparatus are given in ISO 8655-1. For the
metrological requirements, maximum permissible errors, requirements for marking and information to be provided for users for
piston-operated volumetric apparatus, see ISO 8655-2 for piston pipettes, see ISO 8655-3 for piston burettes, see ISO 8655-4 for
dilutors and see ISO 8655-5 for dispensers. Alternative test methods such as photometric and titrimetric methods will be the
subject of a future Part 7 to ISO 8655.
