This specification covers the standard for aluminum-alloy centrifugal castings. This specification does not cover aluminum-alloy centrifugal castings used in aerospace applications. The castings shall be in accordance to the prescribed chemical composition. Chemical composition shall be determined by analyzing samples at the time the castings are poured, or samples taken from castings or tension test specimens. Unless otherwise stated, the tensile strength, yield strength and elongation of test specimens cut from casting shall be in accordance with the standards prescribed herein. If the specimens fail to conform to tension requirements, test bars representative of the castings may be retested in accordance with the replacement tests and retest provisions.1.1 This specification covers aluminum-alloy centrifugal castings designated as shown in Table 1.(A) When single units are shown, these indicate the maximum amounts permitted.(B) Analysis shall be made for the elements for which limits are shown in this table.(C) The following applies to all specified limits in this table: For purposes of determining conformance to these limits, an observed value or a calculated value obtained from analysis shall be rounded to the nearest unit in the last right-hand place of figures used in expressing the specified limit in accordance with the rounding method of Practice E29.(D) In case of discrepancy between the values listed in Table 1 and those listed in the “Designations and Composition Limits for Aluminum Alloys in the Form of Castings and Ingot (known as the ‘Pink Sheets’),” the composition limits registered with the Aluminum Association and published in the “Pink Sheets” shall be considered the controlling composition.(E) “Others” includes listed elements for which no specific limit is shown as well as unlisted metallic elements. The producer may analyze samples for trace elements not specified in the specification. However, such analysis is not required and may not cover all metallic “Others” elements. Should any analysis by the producer or the purchaser establish that an “Others” element exceeds the limit of “Each” or that the aggregate of several “Others” elements exceeds the limit of “Total,” the material shall be considered nonconforming.(F) Other Elements—Total shall be the sum of unspecified metallic elements 0.010 % or more, rounded to the second decimal before determining the sum.(G) If the iron content exceeds 0.45 %, manganese content shall not be less than one half of the iron.(H) For a cross reference of current and former alloy designations see the Aluminum Association’s “Designations and Chemical Composition Limits for Aluminum Alloys in the Form of Castings and Ingot (‘The Pink Sheets’).”1.2 This specification is for aluminum-alloy centrifugal castings used in general purpose applications.

The performance requirements including expansion, flattening, and reverse bend tests; mercurous nitrate test or ammonia vapor test; and nondestructive tests such as eddy-current, hydrostatic, and pneumatic tests are detailed as well.1.1 This specification establishes the requirements for heat exchanger tubes manufactured from forge-welded copper and copper alloy tubing in straight lengths on which the external or internal surface, or both, has been modified by cold forming process to produce an integral enhanced surface for improved heat transfer.1.2 The tubes are typically used in surface condensers, evaporators, and heat exchangers.1.3 The product shall be produced of the following coppers or copper alloys, as specified in the ordering information.Copper or Copper AlloyUNS No. Type of Metal   C12000A DLP Phosphorized, low residual phosphorusC12200A DHP Phosphorized, high residual phosphorusC19200 Phosphorized, 1 % ironC19400 Copper-Iron AlloyC23000 Red BrassC44300 Admiralty, arsenicalC44400 Admiralty, antimonialC44500 Admiralty, phosphorizedC68700 Aluminum BrassC70400 95-5 Copper-NickelC70600 90-10 Copper-NickelC70620 90-10 Copper-Nickel (Modified for Welding)C71000 80-20 Copper-NickelC71500 70-30 Copper-NickelC71520 70-30 Copper-Nickel (Modified for Welding)C72200 Copper-NickelNOTE 1: Designations listed in Classification B224.1.4 Units—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 The following safety hazard caveat pertains only to the test methods described in this specification. 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 Warning—Mercury has been designated by many regulatory agencies as a hazardous substance that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Use caution when handling mercury and mercury-containing products. See the applicable product Safety Data Sheet (SDS) for additional information. The potential exists that selling mercury or mercury-containing products, or both, is prohibited by local or national law. Users must determine legality of sales in their location.1.7 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.
