1 Scope
This European Standard applies to welding consumables for hard facing. The range of application includes
surfaces of new structural components, semi-finished products as well as repair of surfaces of structural
components which have to resist to mechanical, chemical, thermal or combined stress.
This European Standard specifies requirements for classification of the consumables based on their chemical
composition of the all weld metal of covered electrodes, cored wires, cored rods, cored strips, sintered strips,
sintered rods and metal powders and on the chemical composition of solid wires, solid rods, solid strips and
cast rods.
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
document (including any amendments) applies.
EN ISO 544, Welding consumables — Technical delivery conditions for welding filler materials — Type of
product, dimensions, tolerances and markings (ISO 544:2003)
EN ISO 6847, Welding consumables — Deposition of a weld metal pad for chemical analysis (ISO 6847:2000)
EN ISO 14344, Welding and allied processes - Flux and gas shielded electrical welding processes —
Procurement guidelines for consumables (ISO 14344:2002)
ISO 31-0:1992, Quantities and units — Part 0: General principles
3 Classification
The classification is divided in two parts:
a) the first part gives a symbol indicating the product form, see 4.1;
b) the second part gives a alloy symbol indicating the chemical composition, see Table 2.
4 Symbols and requirements
4.1 Symbol for the product form
The following symbols for the product forms shall be used (see Table 1).

EN 14700:2005 (E)
Table 1 — Symbols for the product form
Symbol Product form (consumable)
E covered electrode
S solid wire and solid rod
T cored wire and cored rod
R cast rod
B solid strip
C sintered rod, cored strip and sintered strip
P metal powder
NOTE See also Table A.3.
4.2 Symbol for the chemical composition
The alloy symbols in Table 2 indicate the chemical composition of the all weld metal of covered electrodes,
cored wires, cored strips, sintered strips, sintered rods and metal powder or the chemical composition of solid
wires, solid rods, solid wires and cast rods.
5 Alloy types, form of supply, requirements and applications
The most usual alloy types are listed in Table 2. Typical application is given in Table A.1. The forms of supply
listed in Tables A.2 and A.3 may support the decision making as regards applicable welding processes.
The applications shown in Table A.4 give reference to the suitability of individual alloy types for different kind
of requirements and system structures. It can be concluded that other alloy types may also be considered with
regard to complex kind of requirements.
6 Chemical composition
The chemical analysis shall be performed on specimens of solid wires, solid rods and solid strips according to
EN ISO 6847 respectively or on any suitable all-weld metal specimen and cast rods (covered electrodes,
cored wires, cored strips, sintered rods, sintered strips and metal powder). Any analytical technique can be
used, but in case of dispute reference shall be made to established published methods.
NOTE See Bibliography.
7 Rounding off procedure
For purposes of determining compliance with the requirements of this European Standard, the actual test
values obtained shall be subjected to the rounding-off rules of ISO 31-0:1992, Annex B, Rule A. If the
measured values are obtained by equipment calibrated in units other than those of this standard, the
measured values shall be converted to the units of this standard before rounding off. If an average value is to
be compared to the requirements of this document, rounding off shall be done only after calculating the
average. In the case where the testing document cited in the normative references of this European Standard
contains instructions for rounding off that conflict with the instructions of this standard, the rounding off
requirements of the testing document shall apply. The rounded-off results shall fulfil the requirements of the
appropriate table for the classification under test.

8 Retest
If any test fails to meet the requirement, that test shall be repeated twice. The results of both retests shall
meet the requirement. Specimens for the retest may be taken from the original test sample or from a new test
sample. For chemical analysis, retest need be only for those specific elements that failed to meet their test
requirement. If the results of one ore both retests fail to meet the requirement, the material under test shall be
considered as not meeting the requirements 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 sample or test specimen(s), or in conducting the tests,
the test shall 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 apply.
9 Technical delivery conditions
The technical delivery conditions shall meet the requirements in EN ISO 544 and EN ISO 14344. The
requirements for cored strips, sintered rods and sintered strips as well as for cast rods and metal powders
shall be defined separately.
