|  MIL-E-24403/2C(SH)
Types and sizes of electrodes shall be qualification tested in accordance
with schedule A of table III. Test weldments shall be made in the welding
position and with the type of shielding specified in the classification
requirements (see notes to table I).
The Charpy V-notch and the dynamic tear tests shall be conducted to determine
conformance to the impact requirements of table II.
Types and sizes of electrodes shall be qualification tested in accordance
with schedule B of table III to determine conformance to the requirements of
table 11 herein, except that the smaller size flat or vertical welding
electrodes (of the same type previously qualified) shall be evaluated on
the basis of Charpy V-notch and dynamic tear tests conducted at temperatures
specified in table II, and the explosion crack-starter test shall be
omitted.
When a single electrode formulation is being qualification tested for use
with both shielding gases (MIL-XX0TC and MIL-XX0TM or MIL-XX1TC and
MIL-XX1TM), the schedule A tests shall be conducted for each shielding gas
using one sample of the electrode. Schedule B tests shall be conducted
using the same sample of the electrode and only the shielding gas that
produced the lower impact test results.
