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 2.
The main task of technical committees is to prepare International Standards. 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.
This second edition cancels and replaces the first edition, which has been technically revised.
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
 Part 5: Determination of shrinkage and expansion of well cement formulations at atmospheric pressure
 Part 6: Methods for determining the static gel strength of cement formulations

Introduction
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. The
units do not necessarily represent a direct conversion of SI to US Customary units, or US Customary to SI.
Consideration has been given to the precision of the instrument making the measurement. For example,
thermometers are typically marked in one degree increments, thus temperature values have been rounded to
the nearest degree.
In this part of ISO 10426, calibrating an instrument refers to assuring the accuracy of the measurement.
Accuracy is the degree of conformity of a measurement of a quantity to its actual or true value. Accuracy is
related to precision, or reproducibility of a measurement. Precision is the degree to which further
measurements or calculations will show the same or similar results. Precision is characterized in terms of the
standard deviation of the measurement. The results of calculations or a measurement can be accurate, but
not precise, precise but not accurate, neither and both. A result is valid if it is both accurate and precise.
Well cement classes and grades are defined in ISO 10426-1.
WARNING — This procedure requires the handling of hot, pressurized equipment and materials that
may be hazardous and can cause injury. Do not exceed manufacturer's safety limits. Only trained
personnel should perform these tests.
