NOTES:

Figures 1 and 2 apply to all electrodes.

See 3.9.

Includes ultimate, yield, elongation, and reduction in area.

MT is not required for figure 1 test plates prepared using MIL-7018-M, MIL-8018-C3, MIL-

8018-C3SR, and MIL-9018-M electrode.

When both figures 1 and 2 are applicable, radiography of the figure 1 test assembly will satisfy

the radiography requirements for figure 2 assemblies for Class 2 and 3 electrodes. If the figure 1

assembly is radiographed, the figure 2 test assembly may be eliminated for Class 2 and 3

electrodes.

If chemical analysis is not determined using chemical analysis test pads welded as specified in

MIL-E-22200, chemical analysis shall be determined from milling sample taken from the

centerline of the broken tensile specimens or drillings, or by optical emission spectroscopy on any

sample that is taken and analyzed at the depth of the tensile specimen centerline. In event of

variances with composition requirements or conflicting results by testing activities, analysis shall

be verified by procedures as specified in MIL-E-22200.
