The need to check the electrodes for compliance with the requirements of paragraphs.2.1, 3.3−3.7, 3.11, and also check the moisture content in the coating, and the ratio of the mass of the coating is installed in a standard or technical specifications for the electrodes of specific mark. However, the manufacturer must ensure compliance of the electrodes to these requirements.

(Changed edition, Rev. N 1, 2).

4.2. Each batch should consist of electrodes of the same brand, same diameter.

All included in the batch electrodes should be manufactured in one technological process, on the same equipment, using rods of wire of the same brand with the permanent coating composition of the components of the same parties. The party of the electrodes with rods, of alloy or high-alloy wire must be manufactured using wire of one party.

Notes:

1. The definition of the party wire — GOST 2246.

2. In the cases established by the standard or specifications for the electrodes of specific mark, with the consent of the consumer allowed the manufacturing of a series of electrodes with the use of rods, of alloy or high-alloy wire of two or more parties that are close in chemical composition of the metal. In this case the party should consist of wire of the same brand, same diameter, one destination and one type of surface.

4.3. The mass party of the electrodes depending on their purpose and diameter should not exceed the values given in table.6.
