ASTM A480/A480M-23b(Specification)
Standard Specification for General Requirements for Flat-Rolled Stainless and Heat-Resisting Steel Plate, Sheet, and Strip

ABSTRACT
This specification covers general requirements for flat-rolled stainless and heat-resisting steel plate, sheet, and strip. The steel shall be made by one of the following processes: electric-arc, electric-induction, or other suitable processes. Heat and product analyses shall conform to the chemical requirements for each of the specific elements. The material shall undergo mechanical tests such as tension test, hardness test, and bend test. Special tests like intergranular corrosion test, permeability test, Charpy impact testing and tests for detrimental intermetallic phases in wrought duplex stainless steels shall be also be performed when required.
SCOPE
1.1 This specification2 covers a group of general requirements that, unless otherwise specified in the purchase order or in an individual specification, shall apply to rolled steel plate, sheet, and strip, under each of the following specifications issued by ASTM: Specifications A240/A240M, A263, A264, A265, A666, A693, A793, and A895.  
1.2 In the case of conflict between a requirement of a product specification and a requirement of this specification, the product specification shall prevail. In the case of conflict between a requirement of the product specification or a requirement of this specification and a more stringent requirement of the purchase order, the purchase order shall prevail. The purchase order requirements shall not take precedence if they, in any way, violate the requirements of the product specification or this specification; for example, by waiving a test requirement or by making a test requirement less stringent.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The SI units are shown in brackets, except that when A480M is specified, Annex A3 shall apply for the dimensional tolerances and not the bracketed SI values in Annex A2. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.4 This specification and the applicable material specifications are expressed in both inch-pound and SI units. However, unless the order specifies the applicable “M” specification designation [SI units], the material shall be furnished in inch-pound units.  
1.5 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.

Standard Test Methods for Testing Mechanical Splices for Steel Reinforcing Bars

SIGNIFICANCE AND USE
5.1 Significance:  
5.1.1 The bar-splice assembly test specimen shall closely represent the mechanical splice used in practice. The behavior of the bar-splice assembly embedded in concrete, however, may differ from its behavior during testing where it is not embedded in concrete.  
5.2 Usefulness:  
5.2.1 Testing of mechanical splices for reinforcing bars shall establish the behavior of the bar-splice assembly under the loading conditions described herein for the various test methods to determine the acceptability of the mechanical splice for use in reinforced concrete structural members under specific design criteria.  
5.3 Interpretation of Test Results:  
5.3.1 Similar or better performance of mechanical splices installed in structural members shall be expected only if materials and methods of assembly are similar to the materials and methods used in the tests.
SCOPE
1.1 These test methods cover the testing of mechanical splices for reinforcing bars. The various tests herein described can be specified in total or individually.  
1.2 The test methods herein described are applicable to any type of mechanical splice manufactured to join steel reinforcing bars of any grade (specified minimum yield strength), uncoated or coated.  
1.3 This standard describes only the methods for testing mechanical splices for steel reinforcing bars, but does not quantify the parameters for testing nor acceptance criteria, which must be specified.
Note 1: Various code-writing bodies specify various parameters, such as test loads, number of cycles and test temperature, for testing.  
1.4 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.  
1.5 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.

ASTM A606/A606M-23(Specification)
Standard Specification for Steel, Sheet and Strip, High-Strength, Low-Alloy, Hot-Rolled and Cold-Rolled, with Improved Atmospheric Corrosion Resistance

ABSTRACT
This specification covers standards for high-strength, low-alloy, hot-rolled and cold-rolled steel sheets and strips cut in lengths or coils for structural and miscellaneous purposes. The material shall come in Types 2 and 4 steels having enhanced atmospheric corrosion resistance. The material shall follow specified carbon, manganese, and sulfur contents. Tension test shall be performed and material shall comply with tensile strength, yield strength, and elongation requirements. Edges and surface finish of the materials shall conform to specifications. Guidelines for retests are also given.
SCOPE
1.1 This specification covers high-strength, low-alloy, cold-rolled sheet and strip in cut lengths or coils, hot-rolled sheet and strip steel in cut lengths or coils with ordered thickness less than 0.230 in. [6.0 mm], and hot-rolled sheet coils (not cut lengths) with ordered thickness 0.230 in. [6.0 mm] and thicker, intended for use in structural and miscellaneous purposes, where savings in weight or added durability are important. These steels have enhanced atmospheric corrosion resistance and are supplied in three types or as commercial steel (CS). Type 2 contains 0.20 % minimum copper based on cast or heat analysis (0.18 % minimum Cu for product check). Type 4 and Type 5 contain additional alloying elements and provide a level of corrosion resistance substantially better than that of carbon steels with or without copper addition (Note 1). When properly exposed to the atmosphere, Type 4 and Type 5 steels can be used in the bare (unpainted) condition for many applications. CS is intended for applications that require enhanced atmospheric corrosion resistance which do not require a specified strength. CS shall contain the chemical requirements of Type 2, Type 4, or Type 5. CS as contained within this specification is not associated with the requirements of CS that are referenced in other Subcommittee A01.19 on Steel Sheet and Strip specifications.
Note 1: For methods of establishing the atmospheric corrosion resistance of low-alloy steels, see Guide G101.  
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 Welding—In general, the steels listed in this specification are weldable with commonly obtained welding electrodes. When the steel is to be welded, a suitable welding procedure based on its composition should be used, taking into account intended use and service temperatures.
Note 2: For a general discussion of the weldability of steel and carbon equivalents, consult Appendix X3 of A6/A6M.  
1.4 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.  
1.5 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.

1.3 Plates produced under this specification are subject to impact testing at −320 °F [−195 °C] for Type I or Type III, and −275 °F [−170 °C] for Type II; or at such other temperatures as are agreed upon.  
1.4 The maximum thickness of plates is limited only by the capacity of the material to meet the specified mechanical property requirements.  
1.5 This material is susceptible to magnetization. Use of magnets in handling after heat treatment should be avoided if residual magnetism would be detrimental to subsequent fabrication or service.  
1.6 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.  
1.7 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.  
1.8 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.

ASTM A659/A659M-22(Specification)
Standard Specification for Commercial Steel (CS), Sheet and Strip, Carbon (0.16 Maximum to 0.25 Maximum Percent), Hot-Rolled

ABSTRACT
This specification covers hot-rolled carbon steel sheet and strip, in coils and cut lengths. The cast or heat analysis of the steel shall conform to the chemical composition for copper, nickel, chromium, molybdenum, vanadium, and columbium. The bending properties are measured.
SCOPE
1.1 This specification covers hot-rolled carbon steel (CS) sheet and strip, in coils and cut lengths, in which the maximum of the specified carbon range is over 0.15 and not over 0.25 % and the maximum of the specified manganese range is not over 0.90 %. This material is ordered to chemical composition.  
1.2 This specification is not applicable to the steels covered by Specification A635/A635M.  
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 non-conformance with the standard.  
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.
