8、oped in accordance with the rules of theAmerican National Standards Institute (ANSI). When AWS American National Standards are either incorporated in, ormade part of, documents that are included in federal or state laws and regulations, or the regulations of other govern-mental bodies, their provisi

9、ons carry the full legal authority of the statute. In such cases, any changes in those AWSstandards must be approved by the governmental body having statutory jurisdiction before they can become a part ofthose laws and regulations. In all cases, these standards carry the full legal authority of the

10、contract or other documentthat invokes the AWS standards. Where this contractual relationship exists, changes in or deviations from requirementsof an AWS standard must be by agreement between the contracting parties.AWS American National Standards are developed through a consensus standards developm

It isthe obligation of manufacturers to produce soldered assemblies that have properties suitable for the ap

43、plication. Theproof of production solder soundness is determined by the type and extent of testing and examination applied, which isthe responsibility of the Referencing Document.4.1.1 Each soldering procedure shall be qualified to establish the properties that are expected to result from itsapplica

44、tion to production soldered joints. To qualify a soldering procedure, the following steps are necessary:(1) The employer shall prepare a preliminary soldering procedure specification (SPS) to be used in making a solderedtest assembly. Any format may be used for the SPS, provided all qualification va

45、riables and other applicable informationare included.(2) The actual conditions used in making the soldered test assembly and the results of the required examination andspecimen testing shall be recorded on a soldering procedure qualification record (SPQR). Any format may be used, pro-vided all essen

46、tial and nonessential qualification variables are addressed.(3) When the results meet the acceptance criteria of this document, the qualifying company shall certify by signatureand date that the soldering and testing for procedure qualification are in accordance with AWS B2.3/B2.3M.(4) If the result

47、s do not meet the acceptance criteria, a new soldered test assembly shall be prepared. Soldered testassemblies shall not be repaired.(5) Procedures qualified by one employer are not transferable to another employer.4.1.2 During the making of procedure test assemblies for qualification, see Table A.1

48、, the solderer or soldering oper-ator shall be under the full supervision and control of the Qualifier. The Qualifier is responsible for ensuring proper:(1) Preparation of workpieces for soldering,(2) Documentation of the soldering test assembly variables,(3) Preparation of specimens from the comple

49、ted soldered test assembly,(4) Performance of examination and mechanical tests, and(5) Documentation of results.4.1.3 A change in qualification variable beyond the allowed limits of 4.3 Qualification Variables shall require requal-ification of the SPS and preparation of a new SPS. Changes in other variables shall not require requalification, providedsuch changes are documented in a revised SPS.4.1.4 SPQRs shall not be revised, except to correct errors or add omitted information. However, all such changesshall be identified and dated on the SPQR.4.1.5 SPSs and SPQRs shall be identified accor
