Cable Weight

Knowing the weight of every component on an aircraft, down to the last wire, is vital to good design. This test is to be used to evaluate the weight of a finished cable specimen. Testing follows the same measurement procedure of the AS4373 procedure 1 method of the wire weight test: Measurements of cable weight […] Read more

Wire Weight

Knowing the weight of every component on an aircraft, down to the last wire, is vital to good design. This test is to be used to evaluate the weight of a finished wire specimen, it may also be applied to uninsulated conductor for certain standards. Measurements of wire weight may be made of loose wire […] Read more

Strip Force Test

The strip force test quantitatively evaluates the ease of removing insulation from a finished wire sample. It is important in any electrical system that wire insulation be adherent enough to the conductor to maintain structural integrity and non-adherent enough such that a standard wire stripping tool may readily remove insulation as needed. The insulation of […] Read more

Heat Resistance

The heat resistance test evaluates the ability of an insulative sample to maintain tensile strength after undergoing an elevated temperature exposure. The heat resistance test consists of a heat exposure followed by a tensile elongation test. Specimens are suspended in an oven for a selected temperature and duration, after which time they are removed and […] Read more

Heat Shock

The heat shock test evaluates the ability of an insulative material to endure elevated temperature conditions. Slight variations in test setup exist between the test standards covered by this listing and should be considered before choosing which standard best suits your needs. Each standard covered in this listing involves the same three elements: An elevated […] Read more

Eccentricity of Inner Conductor

This test measures the degree to which the core conductor of a cable is off-center. In cable design, efforts should be made to ensure the conductive core of a cable is as centered as possible to ensure insulative uniformity throughout. The sample’s outer layers are removed to the dielectric core of the cable. The thickness […] Read more

Drip

The drip test is an evaluation of the filler material inside a cable and its tendency to drip from the cable at elevated temperatures. The sample is hung on an apparatus such that one end is held in place while the other is free to hang vertically over a receptacle intended to catch any potential […] Read more

Durometer Hardness

The durometer hardness test is, simply put, a durometer measurement of the hardness of jacket material. The test determines if the jacket material is of adequate harness for use in cable construction. Read more

Barometric Pressure (Reduced)

This listing refers to the barometric pressure test for capacitors. The barometric pressure test evaluates the performance of electrical components at reduced atmospheric pressure such as is expected in high altitude flight. In this evaluation, the capacitor under test is mounted in the pressure chamber and is conditioned in accordance with MIL-STD-202. After conditioning, with […] Read more

Finish

This test is a visual examination of particular categories of wire: ASTM B298 – Silver-Coated Soft or Annealed Copper Wire. ASTM B267 – Wire for Use in Wire Wound Resistors. A Lectromec technician will thoroughly inspect the wire, without magnifying aid, to identify any kinks, cracks, damage, or other abnormalities of the wire. Read more
