ISO7802: 2013: Metallic Material- Wire-Wrapping Test.
ISO7802: 2013: Metallic Material- Wire-Wrapping Test standard specifies the method for determining the ability of wire of diameter or thickness 0,1 to 10 mm inclusive to undergo plastic deformation during wrapping. The test consists of winding a wire to a specified number of turns around a mandrel of the diameter specified in the relevant standard to form a closely wrapped helix. It may also include a specified sequence of windings and unwindings, or even rewindings.
Our metal wire wrapping test machine is used to do wrapping test of 0.1mm – 10mm steel wire, galvanized steel wire, copper and copper alloy line of contact, aluminum wire, high strength wire, etc. It is used for determining the ability of wire of diameter.
NDS-10 Metal Wire Wrapping Testing Machine
1. Main function
This machine is used to do wrapping test of 0.1mm – 10mm steel wire, galvanized steel wire, copper and copper alloy line of contact, aluminum wire, high strength wire, etc. It also can be used for adhesion test of galvanized coating test. In standard, it conforms to ISO7802: 2013: Metallic Material- Wire-Wrapping Test. The test consists of winding a wire to a specified number of turns around a mandrel of the diameter specified in the relevant standard to form a closely wrapped helix. It may also include a specified sequence of windings and un-windings, or even re-windings. It provides reliable measuring method for wire manufacturers and users.
