This standard describes a referee method and a routine method of determining the electrical resistance per unit length of metallic electrical resistance material. The referee method provides for an overall accuracy of 0.2 percent and the routine method provides for an overall accuracy of 1 percent in resistance per unit length on test specimens having a resis-tance of 1 milliohm or more.
