Foreword
ISO (the International Organisation for Standardisation) 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 organisations, 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 standardisation.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
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 document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 10426-2 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures
for petroleum, petrochemical and natural gas industries, Subcommittee SC 3, Drilling and completion fluids
and well cements.
ISO 10426 consists of the following parts, under the general title Petroleum and natural gas industries —
Cements and materials for well cementing:
 Part 1: Specification
 Part 2: Testing of well cements
 Part 3: Testing of deepwater well cement formulations
 Part 4: Preparation and testing of foamed cement slurries at atmospheric pressure
The following part is under preparation:
 Part 5: Determination of shrinkage and expansion of well cement formulations at atmospheric pressure

Introduction
This part of ISO 10426 is based on API RP 10B, 22nd edition, December 1997, addendum 1, October 1999.
Users of this part of ISO 10426 should be aware that further or differing requirements may be needed for
individual applications. This part of ISO 10426 is not intended to inhibit a vendor from offering, or the
purchaser from accepting, alternative equipment or engineering solutions for the individual application. This
may be particularly applicable where there is innovative or developing technology. Where an alternative is
offered, the vendor should identify any variations from this part of ISO 10426 and provide details.
In this part of ISO 10426, where practical, US Customary units are included in brackets for information.
Well cement classes and grades are defined in ISO 10426-1.
