ASTM B223-08(2018)(Test Method)
Standard Test Method for Modulus of Elasticity of Thermostat Metals (Cantilever Beam Method)

ABSTRACT
This test method covers the determination of the modulus of elasticity of thermostat metals within a particular temperature range. The test is done by mounting the specimen as a cantilever and measuring its deflection when subjected to a mechanical load. Each test specimen should be finished to size by careful machining or filing after being roughly cut, slit, or sheared from the samples. Then the specimen is preformed into a shape approximating the segment of a circle and subsequently heat treated to relieve all internal stresses. To permit maximum sensitivity, any oxide and other foreign substances must be carefully removed from all surfaces of the test specimen which directly affect the electrical resistance of the electronic indicator circuit through the testing apparatus. Extra care should be taken so that the load does not overstress the specimen beyond its elastic limit, if this happens, a new specimen shall be substituted and a lighter load should be used. The modulus of elasticity of each test material is computed using the specimen size and the average deflection for a known load.
SCOPE
1.1 This test method covers the determination of the modulus of elasticity of thermostat metals at any temperature between −300 and +1000°F (−185 and 540°C) by mounting the specimen as a cantilever beam and measuring the deflection when subjected to a mechanical load.  
1.2 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.  
1.3 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 become familiar with all hazards including those identified in the appropriate Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, 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.

Standard Specification for High Magnesium Aluminum-Alloy Products for Marine Service and Similar Environments

ABSTRACT
This specification covers high magnesium marine application aluminum-alloy in those alloy tempers for flat sheet, coiled sheet, and plate, in the mill finish that are intended for marine and similar environments. An inspection lot shall consist of an identifiable quantity of material of the same mill form, alloy, temper, cast or melt lot, and thickness, subjected to inspection at one time. The material shall be supplied in the mill finish and shall be uniform as defined by the requirements of this specification and shall be commercially sound. Each coil, sheet and plate shall be examined to determine conformance to this specification with respect to general quality and identification marking. One sample shall be taken from each end of each parent coil, or parent plate. Alloy-tempers are manufactured and corrosion tested for intended use in marine hull construction or in marine applications where frequent or constant direct contact with seawater is expected. The specimen shall be capable of exhibiting resistance to intergranular corrosion as indicated by an acceptable mass-loss when tested and shall also be capable of exhibiting no evidence of exfoliation or corrosion. Under metallographic examination, the microstructure of a sample from each production lot shall be compared to that of the producer-established reference photomicrograph of acceptable material, in the same thickness range. Each shipping container shall be marked with the purchase order number, material size, specification number, alloy and temper, gross and net weights, and the producer's name or trademark.
SCOPE
1.1 This specification covers high magnesium aluminum-alloy products in the mill finish condition that are intended for marine hull construction and other marine applications where frequent or constant direct contact with seawater is expected and for similar environments (Note 1). Aluminum alloy products covered by this specification include the alloy-tempers of flat sheet, coiled sheet, and plate shown in Table 2 [Table 3] and Table 4 [Table 5], and alloy-tempers of extruded profiles shown in Table 6 [Table 7].
Note 1: There are other aluminum alloy-temper products that may be suitable for use in marine and similar environments, but which may not require the corrosion resistance testing specified by B928/B928M. See Specification B209/B209M for other aluminum sheet and plate alloy-temper products. For other aluminum extruded alloy-temper products see Specification B221 or B221M and/or other relevant specifications for aluminum extruded products.  
1.2 Alloy and temper designations are in accordance with ANSI H35.1/H35.1 (M). The equivalent Unified Numbering System alloy designations are those of Table 1 preceded by A9, for example, A95083 for 5083 in accordance with Practice E527.  
1.3 The values stated in either SI units (Table 3 and Table 5) or inch-pound units (Table 2 and Table 4) 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 each other. Combining values from the two systems may result in non-conformance with the standard.  
1.4 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.  
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 E527-23(Practice)
Standard Practice for Numbering Metals and Alloys in the Unified Numbering System (UNS)

SIGNIFICANCE AND USE
4.1 The UNS provides a means of correlating many nationally used numbering systems currently administered by societies, trade associations, and individual users and producers of metals and alloys, thereby avoiding confusion caused by use of more than one identification number for the same material; and by the opposite situation of having the same number assigned to two or more entirely different materials. It also provides the uniformity necessary for efficient indexing, record keeping, data storage and retrieval, and cross referencing.  
4.2 A UNS number is not in itself a specification, since it establishes no requirements for form, condition, quality, etc. It is a unified identification of metals and alloys for which controlling limits have been established in specifications published elsewhere.
Note 5: Organizations that issue specifications should report to appropriate UNS number-assigning offices (3.1.2) any specification changes that affect descriptions shown in published UNS listings.
SCOPE
1.1 This practice (Note 1) covers a unified numbering system (UNS) for metals and alloys that have a “commercial standing” (see Note 2), and covers the procedure by which such numbers are assigned. Section 2 describes the system of alphanumeric designations or “numbers” established for each family of metals and alloys. Section 3 outlines the organization established for administering the system. Section 5 describes the procedure for requesting number assignment to metals and alloys for which UNS numbers have not previously been assigned.
Note 1: UNS designations are not to be used for metals and alloys that are not registered under the system described herein, or for any metal or alloy whose composition differs from those registered.
Note 2: The terms “commercial standing,” “production usage,” and other similar terms are intended to apply to metals and alloys in active commercial production and use, although the actual amount of such use will depend, among other things, upon the type of metals and alloys involved and their application.
The various standardizing organizations involved with the individual industries apply their own established criteria to define the status of a metal or alloy in terms of when a UNS designation number will be assigned. For instance, ASTM Committee A01 requires details of heat analysis, mechanical properties, and processing requirements for addition of a new grade or alloy to its specifications. The Copper Development Association requires that the material be “in commercial use (without tonnage limits);” the Aluminum Association requires that the alloy be “offered for sale (not necessarily in commercial use);” the SAE Aerospace Materials Division calls for “repetitive procurement by at least two users.”
Thus, while no universal definition for usage criteria is established, the UNS numbers are intended to identify metals and alloys that are generally in regular production and use. A UNS number will not ordinarily be issued for a material that has just been conceived or that is still in only experimental trial.

ASTM B899-21(Terminology)
Standard Terminology Relating to Non-ferrous Metals and Alloys

SIGNIFICANCE AND USE
2.1 The terms defined in this document are generic in respect to the standards under the jurisdiction of Committee B02 on Nonferrous Metals and Alloys. The same terms may have different definitions in other ASTM technical committees.  
2.2 Some definitions may differ within the committee because of limitations on items such as weights or dimensions. In such cases the terms will be more precisely defined in the Terminology section of the standards in which these terms are used.
SCOPE
1.1 To promote precise understanding and interpretation of standards, reports, and other technical writings promulgated by Committee B02.  
1.2 To standardize the terminology used in these documents.  
1.3 To explain the meanings of technical terms used within these documents for those not conversant with them.  
1.4 Some definitions include a discussion section, which is a mandatory part of the definition and contains additional information that is relevant to the meaning of the defined term.  
1.5 Definitions of terms specific to a particular standard will appear in that standard and will supersede any definitions of identical terms in this standard.  
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.
