MIL-PRF-85045/20B
TABLE II. Qualification and conformance inspection Continued.
NOTES:
1/
Tolerance on 0.5-km length is ±5 percent, provided that results are normalized to 1 km.
2/
Tolerance on shorter lengths is ±5 percent.
3/
The visual and mechanical inspection shall only be conducted on a 2-m section of each sample.
4/
The same samples as used in the visual and mechanical inspection shall be used.
5/
As stated under the applicable tests in this specification sheet.
6/
The same samples as used in the temperature cycling test shall be used.
7/
A specimen cut from each sample used in the temperature cycling test shall be used.
8/
Three specimens cut from each sample used in the temperature cycling test shall be used.
9/
A specimen cut from each specimen used in the temperature life test shall be used.
10/
The same specimen as used in the tensile loading and elongation test shall be used.
11/
A specimen cut from the specimen used in the thermal shock test shall be used.
12/
Three flat extruded jacket material strips as specified in 4.7.5.15 shall be used in this test.
13/
Specimens cut from the specimen used in the thermal shock test shall be used.
14/
A specimen cut from the specimen used in the thermal shock test or one of the specimens used in the tensile
loading and elongation test shall be used.
15/
Flat extruded jacket material strips (i.e., strips of flat extruded material with the same composition of the
cable jacket and of sufficient dimensions in which dumbbells can be cut) prepared as specified in 4.7.5.14
cited method and obtained from flat extruded material that underwent the thermal shock test shall be used.
16/
Flat extruded jacket material as specified in 4.7.5.15 shall be used in this test.
17/
Specimen cut from the specimen used in the thermal shock test shall be used. Two specimens shall be used
for scraping abrasion, and two specimens shall be used in the cable-to-cable abrasion testing.
18/
A specimen cut from one of the samples used in the temperature cycling test or specimen used in the thermal
shock test shall be used.
Manufacturers who produce products for both MIL-PRF-85045/17 and products for this specification sheet, who
are qualified under M85045/17-01, and pass all applicable tests and inspections specified in table III are qualified
under this specification sheet for M85045/20-01. This qualification by similarity is applicable if the same materials
are used in the previously qualified M85045/17-01 cable and the cable under test.
