Performance Requirements for Wire, Electric, Insulated Copper or Copper Alloy

1990-10-01
HISTORICAL
AS4372
This document covers the requirements for insulated, single-conductor, electric wires with tin-coated, silver-coated, or nickel-coated conductors of copper or copper alloy as specified in the applicable performance sheet. It provides general performance requirements, ratings, and information for various characteristics of insulated wire systems used in aerospace applications. Wire will be assigned a level of performance for many requirements set forth in this standard. These performance levels, in addition to numerical test results, shall be listed in the applicable performance sheet. These test methods contain some new tests that have not been rigorously confirmed as reproducible. Such new methods are identified under the Precision and Bias Statements in the individual Test Methods. Many requirements have multiple levels of performance.

Stress Corrosion of Titanium Alloys, Effect of Cleaning Agents on Aircraft Engine Materials

1990-10-01
CURRENT
ARP1795A
This document establishes a test procedure for determining the propensity of aircraft turbine engine cleaning and maintenance materials for causing stress-corrosion cracking of titanium alloy parts. The evaluation is conducted on representative titanium alloys by determining the effect of contact with cleaning and maintenance materials on tendency of pre-stressed titanium alloys to crack when subsequently heated to elevated temperatures.

Test Methods for Insulated Electric Wire

1990-10-01
HISTORICAL
AS4373
This standard describes test methods for insulated, single conductor, electric wire intended for aerospace applications. Particular requirements for the wire being tested need to be specified in a procurement document or other detail specification. Suggested minimum requirements are included in the notes at the end of some of the test methods. SAE Performance Standard AS4372 uses some of the tests in this document for evaluating comparative performance of aerospace wires.

SEALING INTEGRAL FUEL TANKS

1990-10-01
HISTORICAL
AIR4069
This Aerospace Information Report (AIR) presents preferred practices for sealing and repairing integral fuel tanks. It addresses several basic fuel tank designs as they are currently found in practice and discusses the most practical and conservative methods for producing a reliable, sealed system. Design preferences for optimum sealing are not within the scope of this document. Such discussions can be found in the Air Force sponsored handbook entitled Aircraft Integral Fuel Tank Design Handbook, AFWAL-TR-87-3078. The basic goal in sealing an integral fuel tank is to produce a system that is leak-free for the long term under the environmental and operational conditions expected.
