9、e 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 governmen-tal bodies, their provisions carry the ful

10、l legal authority of the statute. In such cases, any changes in those AWS standardsmust be approved by the governmental body having statutory jurisdiction before they can become a part of those laws andregulations. In all cases, these standards carry the full legal authority of the contract or other

11、 document that invokes theAWS standards. Where this contractual relationship exists, changes in or deviations from requirements of an AWS stan-dard must be by agreement between the contracting parties.AWS American National Standards are developed through a consensus standards development process tha

12、t bringstogether volunteers representing varied viewpoints and interests to achieve consensus. While AWS administers theprocess and establishes rules to promote fairness in the development of consensus, it does not independently test, evalu-ate, or verify the accuracy of any information or the sound

13、ness of any judgments contained in its standards.AWS disclaims liability for any injury to persons or to property, or other damages of any nature whatsoever, whether spe-cial, indirect, consequential, or compensatory, directly or indirectly resulting from the publication, use of, or reliance onthis

AWS disclaims liability for the infringement of anypatent or product trade name resulting from the use of this standard.AWS does not monitor, police, or enforce compliance with this standard, nor d

19、oes it have the power to do so.Official interpretations of any of the technical requirements of this standard may only be obtained by sending a request,in writing, to the appropriate technical committee. Such requests should be addressed to the American Welding Society,Attention: Managing Director,

20、Technical Services Division, 8669 NW 36 St, # 130, Miami, FL 33166 (see Annex B).With regard to technical inquiries made concerning AWS standards, oral opinions on AWS standards may be rendered.These opinions are offered solely as a convenience to users of this standard, and they do not constitute p

21、rofessionaladvice. Such opinions represent only the personal opinions of the particular individuals giving them. These individualsdo not speak on behalf of AWS, nor do these oral opinions constitute official or unofficial opinions or interpretations ofAWS. In addition, oral opinions are informal and

22、 should not be used as a substitute for an official interpretation.This standard is subject to revision at any time by the AWS A5 Committee on Filler Metals and Allied Materials. It mustbe reviewed every five years, and if not revised, it must be either reaffirmed or withdrawn. Comments (recommendat

23、ions,additions, or deletions) and any pertinent data that may be of use in improving this standard are required and should beaddressed to AWS Headquarters. Such comments will receive careful consideration by the AWS A5 Committee on FillerMetals and Allied Materials and the author of the comments wil

24、l be informed of the Committees response to the com-ments. Guests are invited to attend all meetings of the AWS A5 Committee on Filler Metals and Allied Materials toexpress their comments verbally.

35、orewordThis foreword is not part of AWS A5.24/A5.24M:2014, Specification for Zirconium and Zirconium-Alloy WeldingElectrodes and Rods, but is included for informational purposes only.This specification makes use of both U.S. Customary Units and the International System of Units (SI). The measurement

36、sare not exact equivalents; therefore, each system must be used independently of the other, without combining values inany way when referring to filler metal properties. In selecting rational metric units, the AWS A1.1, Metric Practice Guidefor the Welding Industry and International Standard ISO 544

37、, Welding consumablesTechnical delivery conditions forwelding filler metalsType of product, dimensions, tolerances, and markings, are used where suitable. Tables and fig-ures make use of both U.S. Customary and SI Units, which with the application of the specified tolerances provides forinterchangea

38、bility of products in both the U.S. Customary and SI Units.The first Specification for Zirconium and Zirconium Bare Welding Rods and Electrodes was prepared by theSubcommittee on Zirconium Filler Metal in 1976. This edition originally had three electrode classifications, ERZr1,ERZr2 and ERZr3. In th

39、e 1979 edition, the very pure grade of zirconium (ErZr1) was deleted and an additional grade,ERZr4 (with 2%3% Niobium), was added to the specification and includes an addition to the check analysis toleranceby the joint AWS Subcommittee on Titanium and Zirconium Filler Metals. In 1990, the specifica

40、tion was revised toinclude the Acceptance and Certification clauses to the appendix. In 2005, the specification was revised to include an oxy-gen range for all electrode classifications. This was done to take into account the oxygen pickup during the zirconiumwelding process in order to create final

41、 weld strength similar to that of the parent metal. Additionally, the 2005 A5.24specification was the first to use both the U.S. Customary Units and the International System Units (SI). AWSA5.24/A5.24M:2014, Specification for Zirconium and Zirconium-Alloy Welding Electrodes and Rods, is the fourth r

42、evi-sion of the document. This revision primarily includes updates to the reference documents.A vertical line in the margin or underlined text in clauses, tables, or figures indicates an editorial or technical change fromthe 2005 edition.Previous editions of the document are as follows:AWS A5.24-76,
