New ASTM Standard for Determining Tensile Strength of Electrical Conductors Approved


ASTM B986, Test Method for Determination of Tensile Strength by Mass Method for Stranded Conductors Intended for use in Electronic Application, will be used within the electronics and aerospace industries to validate tensile strength specification requirements for electrical conductors. 

ASTM B986 was developed by Subcommittee B01.02 on Methods of Test and Sampling Procedure, part of ASTM International Committee B01 on Electrical Conductors.

Stephen Childers, process engineer, IWG High Performance Conductors Inc., says that methods to determine tensile strength that rely on pulling individual strands from a completed conductor have limitations.

“Cross-sectional areas for a stranded conductor used in electronic applications can be difficult to determine,” says Childers. “The use of a mass method provides an accurate and convenient means to determine tensile strength.”
