36、011.ISO 80000-1:2009, Quantities and 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 t
37、wo parts:a) the first part gives a symbol 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 weld
38、ing shall be the letter “E”.DIN EN ISO 14172:2016-02 EN ISO 14172:2015 (E)5 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 cla
39、ss of alloy deposited, 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 addit
40、ion, with iron more 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
41、 In addition, the 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 calibra
42、ted in units other 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 cal
43、culating the arithmetic 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 app
44、ropriate table for 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 classifica
45、tion under test. 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 proper
46、ties of the all-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.DIN EN ISO 14172:2016-02 EN ISO
