1 Scope
This document specifies technical delivery conditions for filler materials and fluxes for fusion welding.
This document does not apply to other auxiliary materials such as shielding gases.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content constitutes requirements 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,
Iso 14174, Welding consumables — Fluxes for submerged arc welding and electroslag welding — Classification

3 Terms and definitions
No terms and definitions are listed in this document.
5.4 Fluxes
The flux shall be granular and so constituted that it can be conveyed freely by the flux feed system. The particle size distribution shall be uniform and consistent in the different packaging units. The fluxes maybe obtainable in different particle size distributions (see ISO 14174).
6 Rounding procedure
Actual test values obtained shall be subject to ISO 80000-1:2009, 8.3, Rule A. If the measured values are obtained by equipment calibrated in units other than those of this document, the measured values shall be converted to the units of this document before rounding. If an average value is to be compared to the requirements of this document, rounding shall be done only after calculating the average. The rounded results shall fulfil the requirements of the appropriate table for the classification under test.
7 Condition of welding consumables
7.1 Covered electrodes
The electrode covering shall be concentric and consistent along the electrode length in order to avoid asymmetrical melting-off of the covering during welding. The electrode covering shall not exhibit any irregularities, cracks or other surface defects which would adversely affect the welding operation. The coating shall firmly adhere to the core wire and shall not break off during proper handling and usage.
The grip end of the electrode shall be free from covering material over a length of at least 15 mm. NOTE The striking end can include arc ignition enhancing material.
7.2 Wires, rods, and strips
The surface of the welding consumable shall be free from contamination and surface defects that can adversely affect welding. Any surface finish is allowed, provided that the welding operation and the properties of the weld metal are not adversely affected.
8 Marking
8.1 Marking on the product
8.1.1 Covered electrodes
Covered electrodes shall be durably marked on the covering, near the grip end or on the grip end, with
at least an identification traceable to either the supplier trade name or the electrode classification.
8.1.2 WIres and strips
Welding consumables wound on spools, reels, rims or in coils shall be durably marked on the spool, reel rim or coil with an identification traceable to the unique manufacturer or supplier product type.
8.1.3 Rods
Each tungsten inert gas arc welding, plasma arc welding, and oxyfuel gas welding rod shall be durably marked with an identification traceable to the unique manufacturer or supplier product type.
In addition to the traceable identification, it is recommended that at least the compulsory part of the standard designation be used or colour print for identification.
8.2 Marking on the package
The outside of each smallest package unit shall be clearly marked with the following information as a
minimum:
— name of manufacturer or supplier;
— trade name;
— designation in accordance with the relevant International Standard;
— dimensions in accordance with Clause 5:
— for fluxes, particle size range, where applicable, in accordance with ISO 14174;
— batch/heat or lot number;
— type of current and polarity, where applicable;
— number of pieces or nominal net mass;
— redrying instructions or reference to a relevant information source, where applicable,
— approvals, where applicable;
— health and safety warnings in accordance with local, national, and regional standards and regulations, as required.
9 Packaging
The manufacturer, supplier or distributor shall pack welding filler materials and fluxes so that when suitably transported and stored in a dry storeroom, sufficient safeguard against damage and deterioration is provided.
10 Inspection documents
If Inspection documents for a welding filler material or flux are required, they shall be at least in accordance with Iso 14344.
