1 Scope
BS EN ISO 544 specifies technical delivery conditions for filler materials and fluxes for fusion welding.
BS EN ISO 544 does not apply to other auxiliary materials such as shielding gases.

6 Rounding procedure
Actual test values obtained shall be subject to ISO 80000-1:2009, B.3, Rule A. lithe measured values are obtained by equipment calibrated in units other than those of BS EN ISO 544, the measured values shall be converted to the units of BS EN ISO 544 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.
Welding consumables wound on spools, reels, rims or in coils shall be durably marked on the spooi, reel rim or coil with an identification traceable to the unique manufacturer or supplier product type.
813 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.BS-EN-ISO-544-2017
