23、raphy 38 vi 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 f
24、or 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
25、 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 a
26、re 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
27、responsible for identifying any or all such patent rights. ISO 10426-1 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 third
28、edition cancels and replaces the second edition (ISO 10426-1:2005), 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 cemen
29、ts 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 c
30、ement formulations vii Introduction This part of ISO 10426 is based on ISO 10426-1:2005 with the intent that the 24th edition of API Spec 10A will be identical to this part of ISO 10426. It is necessary that users of this part of ISO 10426 be aware that further or differing requirements can be requi
31、red 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 can be particularly applicable where there is innovative or developing techn
32、ology. Where an alternative is offered, it is the responsibility of the vendor to identify any variations from this part of ISO 10426 and provide details. In this part of ISO 10426, where practical, US Customary (USC) or other units are included in brackets for information. The units do not necessar
33、ily represent a direct conversion of SI to USC units, or USC to SI. Consideration has been given to the precision of the instrument making the measurement. For example, thermometers are typically marked in 1 increments, thus temperature values have been rounded to the nearest degree. In this part of
34、 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
35、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 or both. A result is valid if it is b
36、oth accurate and precise. API Specification 10A/ISO 10426-11 Petroleum and natural gas industries Cements and materials for well cementing Part 1: Specification 1 Scope This part of ISO 10426 specifies requirements and gives recommendations for six classes of well cements, including their chemical a
37、nd physical requirements and procedures for physical testing. This part of ISO 10426 is applicable to well cement classes A, B, C and D, which are the products obtained by grinding Portland cement clinker and, if needed, calcium sulfate as an interground additive. Processing additives can be used in
38、 the manufacture of cement of these classes. Suitable set-modifying agents can be interground or blended during manufacture of class D cement. This part of ISO 10426 is also applicable to well cement classes G and H, which are the products obtained by grinding clinker with no additives other than on
39、e or more forms of calcium sulfate, water or chemical additives as required for chromium (VI) reduction. 2 Normative references The following referenced documents are indispensable for the application of this document.
