MIL-DTL-83420 Wire Rope, Flexible, For Aircraft Control, General Specification ForThis specification covers the requirements for carbon steel and corrosion resistant steel aircraft control flexible wire rope. Type I wire rope will be capable of operation within a -65 degrees F to +250 degrees F \(-54 degrees C to +121 degrees C\) temperature range in wind, dust, fuel, and oil spills, in wash-down and other environmental stresses and aircraft experiences. Type II wire rope will be capable of operation within a -65 degrees F to +200 degrees F \(-54 degrees C to +94 degrees C\) temperature range in wind, dust, fuel, and oil spills, in wash-down and other environmental stresses and aircraft experiences.

4.3 Conformance inspection. Conformance inspection shall consist of individual tests

and sampling tests.

4.3.1 Individual tests. Each size wire rope of each type, composition, and construction

furnished under each contract or order shall be subject to the following tests as described under

Ductility of steel (4.4.1.1).

Adherence of coating (4.4.1.2).

Examination of product (4.4.2).

Concentricity tests for type II wire rope (4.4.2.1).

Conformance test to preforming of cable (4.4.2.2).

Color-coding identification (4.4.11).

4.3.2 Sampling plan.

4.3.2.1 Sample.

4.3.2.1.1 Wire rope. When conducting the sampling tests specified herein, one

continuous sample of sufficient length shall be taken after any discard has been removed from

the head or starting end of the first manufacturing reel for each lot of wire rope.

4.3.2.1.2 Wire. When conducting the sampling tests specified herein, one random

sample of wire, of sufficient length to meet testing requirements, shall be taken from the wire lot.

4.3.2.2 Lot.

4.3.2.2.1 Wire rope. A lot shall consist of not more than 20,000 feet of wire rope of the

same construction and diameter produced continuously by one machine or by one series of

progressive processing machines.

4.3.2.2.2 Wire. A lot shall consist of wire of one size produced from the same heat of

steel in one continuous process.

4.3.2.3 Specimen. A specimen is a section of wire rope or wire cut from a sample for the

performance of a testing method. All specimens shall be taken from the lot furnished under that

specific order.

4.3.3 Sampling tests. The conformance sampling tests shall be performed in accordance

with the paragraphs listed in table V.

4.3.4 Certification. For each contract or order, the wire rope manufacturer shall certify

that the product satisfactorily passed the conformance inspections (see 4.3.1 and 4.3.3) of this

specification. The certification shall include, as a minimum, actual results of the tests specified

herein and shall be retained on file at the manufacturer's facility for a minimum of 7 years.
