This specification covers castings, iron-chromium-nickel-molybdenum corrosion-resistant, duplex(austenitic/ferritic) for general application. Castings shall be heat treated in accordance with the required procedure and heat-treat temperature. Proper heat treatment of these alloys is usually necessary to enhance corrosion resistance and in some cases to meet mechanical properties. Minimum heat-treat temperatures are specified; however, it is sometimes necessary to heat-treat at higher temperatures, hold for some minimum time at temperature and then rapidly cool the castings in order to enhance the corrosion resistance and meet the required mechanical properties. The steel shall conform to the required chemical composition for carbon, manganese, silicon, phosphorus, sulfur, chromium, nickel, molybdenum, copper, tungsten, and nitrogen. Castings shall be marked for material identification with the specification designation and grade.1.1 This specification covers a group of cast duplex stainless steels (austenitic/ferritic).1.2 The duplex stainless steel alloys offer a combination of enhanced mechanical properties and corrosion resistance when properly balanced in composition and properly heat treated. Ferrite levels are not specified, but these alloys will develop a range of approximately 30 to 60 % ferrite with the balance austenite. It is the responsibility of the purchaser to determine which grade shall be furnished depending on design and service conditions, mechanical properties, and corrosion-resistant characteristics.NOTE 1: Because of the possibility of precipitation of embrittling phases, the grades included in this specification are not recommended for service at temperatures above 600 °F [315 °C].1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.1.3.1 Within the text, the SI units are shown in brackets.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 Chemical-resistant polymer machinery grouts are used to provide precision support for machinery or equipment.NOTE 2: The machinery or equipment or support bases or plates, or combination thereof, are positioned to the precise elevation and location required. The bases or plates are typically placed on prepared foundations and supported on temporary shims or support bolts (jack screws). Forms are installed to contain the flowable grout. The grout is poured around the perimeter in such a manner as to allow the grout to flow around and under the equipment base or plates. The grout subsequently hardens to provide a strong rigid support layer capable of withstanding the stresses transferred by the equipment to the foundation. Although the actual machinery base plate is typically metal and the cover plate in this test uses acrylic glass, different grouts using acrylic glass cover plates has proven useful for comparative purposes as described in this test in laboratory conditions.5.2 In addition to the required physical properties of the grout, the flow and bearing area achieved are important considerations for effective grout installation. The two characteristics measured by this test method are flow and bearing area.5.3 The flow test simulates typical application conditions for a flowable polymer machinery grout in a laboratory environment. It may be used to evaluate the suitability of a particular grout for a specific application, to compare the flowability and bearing area of two or more grouts, or to evaluate the effects of formulation changes, temperature, mixing techniques, or other factors on flowability.5.4 The estimated amount of upper grout surface contact in percent can be used to compare two or more grouts or show the effects of temperature, formulation changes, or other factors on bearing area. A limited set of results using visual guides (see Fig. 1 and Fig. 2) is used to classify the bearing as “high”—greater than 85 %,” “medium—70 to 85  %,” and “low—less than 70 %.”1.1 This test method covers the measure of flowability of chemical-resistant polymer machinery grouts as evaluated in a 50-mm [2-in.] or 25-mm [1-in.] pour thickness in a laboratory setting. The test method provides for the assessment of upper surface plate contact area (bearing area). These grouts will typically be at least two component formulations that may be used for installations where grout thickness will range from 25 to 150 mm [1 to 6 in.] underneath the base or plates being grouted.1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 This test method offers a means of comparing the relative linear shrinkage and coefficient of thermal expansion.4.1.1 The material to be tested is placed in the mold in a fluid or plastic state. As the material makes a transition to a solid state, it adheres to and captures the end studs.4.1.2 The linear shrinkage measured is the change in length that occurs after the material is rigid enough and strong enough to move the studs.4.2 This test method can be used for research purposes to provide information on linear changes taking place in the test materials. Other dimensional changes may occur that do not manifest themselves as changes in length.1.1 This test method covers the measurement of the linear shrinkage during setting and curing and the coefficient of thermal expansion of chemical-resistant mortars, grouts, monolithic surfacings, and polymer concretes.1.2 A bar of square cross-section is cast to a prescribed length in a mold that holds measuring studs that are captured in the ends of the finished casting.1.2.1 The change in length after curing is measured and used to calculate shrinkage.NOTE 1: Shrinkage determinations should not be made on sulfur mortars, since this test method cannot truly reflect the overall linear shrinkage of a sulfur mortar.1.2.2 The change in length at a specific elevated temperature is measured and used to calculate the coefficient of thermal expansion.1.3 This test method is limited to materials with aggregate size of 0.25 in. (6 mm) or less.1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
