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.

The procedures 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 document should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

ISO draws attention to the possibility that the implementation of this document may involve the use of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a) patent(s) which may be required to implement this document. However, implementers are cautioned that this may not represent the latest information, which may be obtained from the patent database available at www.iso.org/patents.

Introduction

This document addresses the needs of piston-operated volumetric apparatus (POVA) users and quality and laboratory managers, and serves as a basis for:

user guidance, training, and qualification;
establishing POVA performance and test requirements to ensure fitness for their intended use;
selecting pipetting equipment.

The tests specified in the ISO 8655 series are intended to be carried out by trained personnel.

1 Scope

This document provides user guidance regarding the selection of piston-operated volumetric apparatus (POVA) (including exchangeable parts) and best practices for their use.

This document also specifies requirements for user training and competence. Further, this document introduces performance tolerances and testing of POVA to ensure fitness for their intended use.
