35 Bibliography 38 v 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 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 10426-1 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 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 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 vi 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 required 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 technology 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 not necessarily 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 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 or both A result is valid if it is both accurate and precise vii API Specification 10A/ISO 10426-1 Petroleum and natural gas industries – Cements and materials for well cementing Part 1: Specification Scope This part of ISO 10426 specifies requirements and gives recommendations for six classes of well cements, including their chemical and 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 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 one or more forms of calcium sulfate, water or chemical additives as required for chromium (VI) reduction Normative references The following referenced documents are indispensable

(prepared in accordance with Clause 7) into the inverted slurry container NOTE Slurry segregation can occur during the filling operation This can be reduced by stirring the slurry in the mixing container with a spatula while pouring Segregation is less of a problem when the time from cessation of mixing to completing the filling operation is kept to a minimum 10.3.2.2 When the slurry container is full, strike the outside of the container and remove air that rises to the top of the slurry 10.3.2.3 Then, secure the slurry container base in place 10.3.2.4 Then, secure the centre plug (pivot bearing) into the container base 10.3.3 Initiation of test 10.3.3.1 Place the slurry container on the drive table in the pressure vessel, start rotation of the slurry container, place the potentiometer mechanism so as to engage the shaft drive bar, and begin filling the vessel with oil 10.3.3.2 Close the head assembly of the pressure vessel securely, insert the thermocouple, and partially engage its threads 10.3.3.3 After the pressure vessel is completely filled with oil, tighten the threads of the thermocouple 10.3.3.4 Initiate the test by applying pressure and temperature within after cessation of mixing 10.3.4 Temperature and pressure control During the test period, increase the temperature and pressure of the cement slurry in the slurry container in accordance with the appropriate specification schedule given in Table 9, Table 10, or Table 11 During the pressure and temperature ramp of schedules 4, and 6, the temperature and pressure shall be maintained within ± °C (± °F) and ± MPa (± 300 psi), respectively, of the appropriate elapsed time versus temperature and pressure target 30 CEMENTS AND MATERIALS FOR WELL CEMENTING—PART 1: SPECIFICATION Within 10 after the end of the ramp, the temperature and pressure shall be within ± °C (± °F) and ± 0,7 MPa (± 100 psi), respectively, of the specified values Determine the temperature of the cement slurry for specification testing by the use of a temperature-measuring device located in the centre of the sample container The tip of the thermocouple shall be vertically positioned within the paddle shaft in the slurry cup in such a way that it is between 45 mm (1,77 in) and 89 mm (3,5 in) above the inside of the base of the sample container As there are many models of consistometers having different dimensions, care shall be taken to ensure that the thermocouple used is compatible with the consistometer and that the position of the tip of the thermocouple is in the correct location specified

cement For sacked cement, the information required shall be marked on each sack; for bulk cement, the information required shall be marked or attached to the bill of lading on each shipment: a) manufacturer's name; b) class and sulfate-resistance grade of cement; c) net mass 12 Packing Well cement shall be furnished in bulk or in sacks Each sack shall contain a specified net mass of ± % The average net mass of % of all sacks in a shipment, taken at random, shall not be less than the specified mass A cement sack should be resistant to moisture, resistant to damage during handling and easy to cut during transfer to bulk facilities Cement sacks should typically consist of up to six paper layers with a minimum areic mass of 70 g/m2 (0.014 lbm/ft2) each with up to two polyethylene or polypropylene layers with an areic mass of 15 g/m2 (0.003 lbm/ft2) to 24 g/m2 (0.005 lbm/ft2) each included between the first and fifth paper layers Up to two asphalt or bitumen layers may be included to further improve resistance to damage Flexible bulk cement containers should provide an acceptable tensile strength (safety factor to minimum) They should also be resistant to ultraviolet radiation when polyethylene or polypropylene layers are used and be suitably moisture-proof 13 Bentonite Bentonite is a naturally occurring clay mineral, composed primarily of smectite Non-treated bentonite, for use in well cementing, is dried and ground, but not chemically treated during processing Bentonite meeting the requirements of this part of ISO 10426 for use in well cementing shall meet all the requirements for non-treated bentonite in accordance with ISO 13500 Table 13 — Bentonite acceptance requirements NOTE Requirement Specification Yield point/plastic viscosity ratio 1,5 maximum Dispersed plastic viscosity 10 cP minimum Dispersed filtrate volume 12,5 ml maximum See ISO 13500 for test procedures Annex A (informative) Calibration procedures for thermocouples, temperature measuring systems, and controllers A.1 Calibration methods There are several satisfactory methods for calibrating thermocouples, including methods supplied by equipment manufacturers See ASTM E220 for a more complete discussion of these procedures No ASTM procedures for calibration of temperature measuring systems are available A.2 Thermocouple calibration A.2.1 Apparatus A.2.1.1 General The individual pieces of apparatus required to carry out the calibration depend on the particular technique selected Those features that need special attention, regardless of the technique, are highlighted in A.2.1.2 to A.2.1.4 A.2.1.2 Heating environment The heating medium should permit proper immersion of both the test thermocouple (the one being calibrated) and the reference thermocouple or reference thermometer The apparatus should be capable of maintaining a stable temperature that is uniform throughout the test section A.2.1.3 Temperature measurement The reference temperature of the heating medium may be measured by using either a thermometer or a thermocouple The accuracy of the reference measuring device should be traceable to the reference of the national body responsible for standards of temperature measurement, for example the NBS certification in the USA A.2.1.4 Thermocouple voltage output If a thermocouple is used to sense the reference temperature, the voltage output from the reference thermocouple and test thermocouple should be determined as described in applicable national standards, such as ASTM E220 In this case, tables of temperature vs voltage for the type of thermocouple being used should be consulted to determine the temperature Alternatively, a direct-reading, temperature-compensated readout instrument may be used The accuracy of the instrument should be traceable to national standards certification A.2.2 Procedure A.2.2.1 With the exception of the indicating instruments, the specific procedures are detailed in applicable national standards, such as ASTM E220 The items in A.2.2.2 through A.2.2.6 require special attention or are related to the use of the indicating type of equipment A.2.2.2 The test and reference thermocouples or thermometers should be placed as close together as possible in the heating medium 33 34 CEMENTS AND MATERIALS FOR WELL CEMENTING—PART 1: SPECIFICATION A.2.2.3 After each change in heating level, the temperature should be allowed to remain at a stable value for 15 before reading the reference temperature (or voltage) and the test thermocouple temperature (or voltage) A.2.2.4 Several (more than three) test temperatures that span the operating range of the equipment should be used in the calibration procedure A.2.2.5 If the test thermocouple does not accurately sense the temperature, a calibration curve should be drawn and used to correct the indicated temperatures from the test thermocouple Occasionally, small inaccuracies in thermocouple response can be compensated for during the calibration of the temperature measuring system being used in conjunction with the thermocouple (see A.3) A.2.2.6 If the test thermocouple error is greater than that specified by the manufacturer, the thermocouple should be replaced by one that meets the thermocouple accuracy limits The ASTM E220 classification “special” type J thermocouple has error limits equal to or better than ± °C (± °F) up to 277 °C (530 °F) A.3 Calibration of temperature measuring systems and controllers A.3.1 Apparatus The calibration of temperature-measuring systems and controllers requires a millivolt source, the correct connecting thermocouple extension cable for the type of thermocouple being used and, possibly, a thermometer and a table of reference voltages Signal sources, or calibrators, are of two types, namely, uncompensated and cold-junction-compensated Several commercial calibrators are available that are cold-junction-compensated and have a digital display of the temperature equivalent to the millivolt signal being supplied The accuracy of all calibration apparatus should be traceable to national-standards certification Some older galvanometer-type temperature-indicating instruments and controllers require a stronger signal for operation than the newer potentiometric and digital-type temperature measuring systems and controllers and, therefore, require a calibrator with sufficient signal strength to give an accurate calibration A.3.2 Procedure A.3.2.1 The manufacturer's procedure for calibrating temperature-measuring systems and controllers should be followed The items in A.3.2.2 to A.3.2.5 require special attention A.3.2.2 The thermocouple extension cable should be fitted with a proper thermocouple grade adapter to permit plugging it into the same receptacle used for connecting the test equipment thermocouple Care should be taken to ensure the correct polarity of the connections Calibrators, temperature-measuring systems, and controllers should be allowed proper warm-up time, as specified by the manufacturer, for greatest accuracy A.3.2.3 It is only necessary that thermocouple calibrators with cold-junction compensation be properly connected with the proper thermocouple extension cable and thermocouple connectors The temperaturemeasuring systems and/or controllers using this signal should have the same temperature readout, within the accuracy of the temperature or controllers as supplied by the manufacturer A.3.2.4 Uncompensated thermocouple calibrators require a thermometer to determine the cold-junction temperature of the thermocouple extension cable connection of the calibrator This cold-junction temperature is set on the calibrator by the operator A.3.2.5 The use of an uncompensated millivolt potentiometer requires that the temperature at the calibrator/thermocouple extension cable terminals be read with a thermometer of known accuracy The millivolt equivalent of this temperature is then subtracted from the equivalent test millivolt signal to obtain the calibrator millivolt signal used These voltages may be found in reference mV/temperature tables for the type of thermocouple in use Annex B (informative) Use of the API Monogram by Licensees B.1 Scope The API Monogram Program allows an API Licensee to apply the API Monogram to products The API Monogram Program delivers significant value to the international oil and gas
