18、SO 14172:2015ISO 14172:2015(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interest
19、ed in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Co
20、mmission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents
21、 should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). 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 f
22、or identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents). Any trade name used in this document is information given for the
23、 convenience of users and does not constitute an endorsement.For an explanation on the meaning of ISO specific terms and expressions related to conformity assessment, as well as information about ISOs adherence to the WTO principles in the Technical Barriers to Trade (TBT) see the following URL: For
24、eword - Supplementary informationThe committee responsible for this document is ISO/TC 44, Welding and allied processes, Subcommittee SC 3, Welding consumables.Requests for official interpretations of any aspect of this International Standard should be directed to the Secretariat of ISO/TC 44/SC 3 v

26、elding consumables Covered electrodes for manual metal arc welding of nickel and nickel alloys Classification1 ScopeThis International Standard prescribes requirements for the classification of nickel and nickel-alloy covered electrodes for manual metal arc welding and overlaying. It includes those
27、compositions in which the nickel content exceeds that of any other element.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated refe
28、rences, the latest edition of the referenced document (including any amendments) applies.ISO 544, Welding consumables Technical delivery conditions for filler materials and fluxes Type of product, dimensions, tolerances and markingsISO 6847, Welding consumables Deposition of a weld metal pad for che

Amended by ISO 15792-1:2000/Amd 1:2011.ISO 80000-1:2009, Quantities and
30、 units Part 1: General3 ClassificationA covered electrode shall be classified in accordance with the chemical composition of the all-weld metal as given in Table 1 and the mechanical properties listed in Table 2. The symbol for the classification is divided into two parts:a) the first part gives a s
31、ymbol indicating the product/process to be used;b) the second part gives a symbol indicating the chemical composition of the all-weld metal.4 Symbols and requirements4.1 Symbol for the product/processThe symbol for covered electrodes used for manual metal arc welding shall be the letter “E”. ISO 201
32、5 All rights reserved 1BS EN ISO 14172:2015ISO 14172:2015(E)4.2 Symbol for the chemical composition of the all-weld metalThe 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 depo
33、sited, where2 indicates no significant alloy addition,4 indicates significant copper addition (nickel-copper alloys),6 indicates significant chromium addition, with iron less than 25 % (nickel-chromium-iron and nickel-chromium-molybdenum alloys),8 indicates significant chromium addition, with iron m
34、ore than 25 % (nickel-iron-chromium alloys),10 indicates significant molybdenum addition without significant chromium addition (nick-el-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, th
35、e chemical symbol can be used.4.3 Rounding procedureFor purposes of determining compliance with the requirements of this International Standard, the actual test values obtained shall be subject to ISO 80000-1:2009, B.3, Rule A. If the measured values are obtained by equipment calibrated in units oth
36、er than those of this International Standard, the measured values shall be converted to the units of this International Standard before rounding. If an arithmetic average value is to be compared to the requirements of this International Standard, rounding shall be done only after calculating the ari
37、thmetic average. If the test method cited in Clause 2 contains instructions for rounding that conflict with the instructions of this International Standard, the rounding requirements of the test method standard shall apply. The rounded results shall fulfil the requirements of the appropriate table f
38、or the classification under test.5 Chemical analysisChemical analysis shall be performed on any suitable all-weld metal test specimen. 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.
39、 Any analytical technique can be used; but, in case of dispute, reference shall be made to established published methods.6 Mechanical properties of the all-weld metalMechanical properties are not part of the designation, but they are required for classification. The mechanical properties of the all-
40、weld metal, deposited using covered electrodes in accordance with Table 1, shall be determined using a test assembly type 1.3 in accordance with ISO 15792-1:2000 with 4,0 mm electrodes. The minimum tensile properties shall be in accordance with Table 2.2 ISO 2015 All rights reservedBS EN ISO 14172:2
