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 documents 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 ).

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents ).

Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.

This document was prepared by Technical Committee ISO/TC 48, Laboratory equipment, in collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/TC 332, Laboratory equipment, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

This second edition cancels and replaces the first edition (ISO 8655-7:2005), which has been technically revised. It also incorporates the Technical Corrigendum ISO 8655-7:2005/Cor.1:2008.

The main changes are as follows:

• a gravimetric test method was added (see 8.2);
• a photometric/gravimetric hybrid test method was added (see 8.5);
• a batch testing method was added (see 8.7);
• measurement procedures for all methods are given in normative Annexes A to E;
• standard dispense procedures for POVA described in ISO 8655-2, ISO 8655−3, ISO 8655−4, ISO 8655−5, and ISO 8655−9 were added (see Clause 9);
• requirements for operator qualification have been added (see 4.3);
• requirements for testing of multi-channel POVA is described in more detail, with specific procedures given for these apparatus (see 8.5, and Annex D);
• Annexes A, B, and C of the first edition have been deleted and replaced.

A list of all parts in the ISO 8655 series can be found on the ISO website.

This corrected version of ISO 8655-7:2022 incorporates the following corrections:

• decimal spaces replaced with commas in Table B.5 and Table C.3;
• Table D.5, the dash is replaced with “25” in the second column, the concentration unit was updated to “mg/ml” and the concentration values for “mg/ml” were updated;
• D.3.2.3, the concentration unit for 16,7 was updated from “µg/ml” to “mg/ml”;
• D.3.2.4, the nominal concentration for 384-well plates was updated to 29,3 µg/ml;
• D.4.5.1 and D.4.5.2, the term “conversion factor” is replaced with “correction factor”;
• the key to Formula (A.2) has been corrected;
• the year of publication of ISO 23783-2:— has been updated to ISO 23783-2:2022.

Introduction

The ISO 8655 series addresses the needs of:

• manufacturers, as a basis for quality control including ここで, appropriate, the issuance of manufacturer’s declarations;
• calibration laboratories, test houses, users of the equipment and other bodies as a basis for independent calibration, testing, verification, and routine tests.

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

1 Scope

This document specifies alternative measurement procedures for the determination of volume of piston-operated volumetric apparatus.

The procedures 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 delivery process (Ex). Methods described in this document are suitable for various maximum nominal volumes of piston-operated volumetric apparatus. It is the responsibility of the user to select the appropriate method.
