12、 of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee.
13、International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance wit
14、h the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approv
15、al by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 14172 was prepared by Technical Committe

This International Standard has been revised to assist an alignment betw
18、een the documents prepared by CEN/TC 121/SC 3 in their work towards a CEN standard for covered electrodes for nickel-base alloys and those drawn up by Commission II of the IIW. The classifications in the IIW proposals remain largely unaltered but the designations now allow for the optional use of a
19、chemical symbol in the form widely favoured in Europe. Requests for an official interpretation of technical aspects of this international Standard should be directed to the secretariat of ISO/TC 44/SC 3 via the users national standardization body.

22、 consumables Covered electrodes for manual metal arc welding of nickel and nickel alloys Classification 1 Scope This International Standard prescribes requirements for the classification of nickel and nickel alloy covered electrodes for manual metal arc welding and overlaying. It includes those comp
23、ositions in which the nickel content exceeds that of any other element. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced

The symbol for the classification is divided into two parts: a) the first part gives a symbol indicating the p
27、roduct/process to be used; b) the second part gives a symbol indicating the chemical composition of the all-weld metal. 4 Symbols and requirements 4.1 Symbol for the product/process The symbol for covered electrodes used for manual metal arc welding shall be the letter E.

29、chemical composition of the all-weld metal The symbol for the chemical composition of the all-weld metal shall comprise “Ni” plus four digits as shown in Table 1. The first digit is an indicator of the class of alloy deposited: 2 No significant alloy addition. 4 Significant copper addition (nickel-c
30、opper alloys). 6 Significant chromium addition, with iron less than 25 % (nickel-chromium-iron and nickel-chromium- molybdenum alloys). 8 Significant chromium addition, with iron more than 25 % (nickel-iron-chromium alloys). 10 Significant molybdenum addition without significant chromium addition (n
31、ickel-molybdenum alloys). The remaining digits indicate the particular alloy deposited. The basis of the system of designation is described in Annex A. NOTE In addition the chemical symbol may be used. 5 Chemical analysis Chemical analysis shall be performed on any suitable all-weld metal test speci
32、men. In case of dispute, the test specimen specified in ISO 6847 shall be used. The test results shall meet the requirements of Table 1 for the classification under test. Any analytical technique may be used, but in case of dispute reference shall be made to established published methods. 6 Mechanic
33、al properties of the all-weld metal Mechanical properties are not part of the designation but they are required for classification. The mechanical properties of the all-weld metal, deposited using covered electrodes in accordance with Table 1, shall be determined using a test coupon in accordance wi
34、th ISO 15792-1:2000, type 1.0. The minimum tensile properties shall be in accordance with Table 2. 7 Retests If any test fails to meet the requirement, that test shall be repeated twice. The results of both retests shall meet the requirements. Specimens for retesting may be taken from the original t
35、est assembly or from a new test assembly. For chemical analysis, retests need be only for those specific elements that failed to meet their test requirement. If the results of one or both retests fail to meet the requirement, the material under test shall be considered as not meeting the requirement
36、s of this specification for that classification. In the event that, during preparation or after completion of any test, it is clearly determined that prescribed or proper procedures were not followed in preparing the weld test assembly or test specimen(s), or in conducting the tests, the test shall
37、be considered invalid, without regard to whether the test was actually completed, or whether the test results met, or failed to meet, the requirement. That test shall be repeated, following proper prescribed procedures. In this case, the requirement for doubling the number of test specimens does not
