MIL-DTL-13080E
4.4.1 First article samples. First article test samples shall be obtained from the material to be
furnished for each type. Samples shall be selected at random from electrodes which have been
manufactured using the same production processes, procedures, and equipment which will be used in
filling the contract. The samples shall be selected from either filled unit containers or from the
production line immediately before packaging. If selected from the production line, the total sample
shall be selected throughout the run so all parts of the run are represented.
4.4.1.1 Sampling for visual, dimensional, and concentricity requirements. The number of random
samples selected to verify compliance with visual, dimension, and concentricity requirements, from
each lot of electrodes shall be defined by the procuring activity (see 6.2).
4.4.1.2 Sampling for tests for all other requirements. For all other tests, select a random sample
from each lot of electrodes as defined by the procuring activity (see 6.2).
4.4.2 Completion of first article inspection. Upon completion of the first article inspection, all the
applicable inspection reports and when applicable, recommendations and comments pertinent for use
in monitoring production shall be forwarded to the cognizant Government activity. The first article
test report shall consist of the following:
a. Concentricity of the electrode coverings (see 3.4.1).
b. The type classification for which approval is sought (see 1.2).
c. The principal compounds and nominal percentages thereof in the coverings.
d. The range of chemical composition of the deposited weld metal (see 3.5.1).
e. Results of all tests, referring specifically to the appropriate paragraph numbers of the
specification. If a particular requirement is not applicable, the report shall so state it.
f. A complete description of the inspection testing equipment and procedures.
g. Copies of inspection log sheets.
4.5 Quality conformance inspection. Quality conformance inspection consists of tests for the
following requirements only. The applicable methods of test are specified in the respective sub-
paragraphs of 4.6.
a. Dimensions and tolerances (see 3.4.1, 3.4.8.1, 3.4.8.2, 3.6.1 and 3.6.2).
b. Concentricity of covering (see 3.4.1).
c. Chemical composition of deposited weld metal (see 3.5.1).
d. Workmanship (see 3.12).
4.5.1 Sampling for examination and test of electrodes. Sample electrodes shall be selected either
from filled unit packages or from the production line after the baking operation. The unit packages
required for this examination shall be selected from the sample of packages used for 4.4.1.1 and
4.4.1.2. If sample electrodes are selected from filled unit packages, the total sample shall be defined
by the procuring activity (see 6.2). Lot size shall be expressed in pounds. A minimum number of
unit packages shall be selected from the production line, the total sample shall be equivalent to the
above and the electrodes shall be selected throughout the production period so that all parts of the
lot are represented. The electrodes selected shall be identified as to type, lot, size and other available
information such as contract or order number being filled.
