FED STD 228 Test Methods for Insulated Cables and Wires

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of FED STD 228 testing. This standard gives general physical, electrical and chemical methods for testing insulated wires and cables for electrical purposes for compliance with the requirements of Federal and Military standards and other relevant standards. It is prepared to eliminate unnecessary or undesirable variations in test procedures.

This standard does not cover the specific test methods applied to certain wires and cables described in the relevant detail specifications and all test methods for wires and cables used in industry. In case of conflict between the provisions of these methods and the provisions of individual test procedures or specifications for a particular material, the latter should take precedence.

The standard covers a range of test methods to evaluate various aspects of cable and wire performance, including:

• Mechanical tests: These tests evaluate the physical properties of the cable or wire, including its flexibility, tensile strength, and abrasion resistance. Examples of mechanical testing include the mandrel test, the bend test, and the tensile test;
• Electrical tests: These tests evaluate the electrical properties of the cable or wire, including its insulation resistance, dielectric strength, and capacitance. Examples of electrical tests are insulation resistance test, voltage withstand test, and capacitance test;
• Environmental tests: These tests evaluate the performance of cable or wire under various environmental conditions such as high and low temperatures, humidity and exposure to chemicals. Examples of environmental tests are cold bending test, heat aging test and chemical resistance test;
• Fire resistance tests: These tests evaluate the resistance of the cable or wire to ignition or spread of flames in a fire. Examples of fire resistance tests include the vertical flame test and the oxygen index test.

FED-STD-228 also provides guidance on the selection of appropriate test methods based on the type of cable or wire being tested and its intended use. The standard specifies the test conditions and procedures for each test method, as well as the acceptance criteria that must be met for the cable or wire to pass the test.

Overall, FED-STD-228 is an important resource for the cable and wire industry and provides standardized test methods and criteria for evaluating the performance of insulated cables and wires.
