• resistivity
• electrical steel
• 4-terminal method

The van-der-Pauw (VDP) method and the traditional measurement method are used to measure the resistivity of the electrical steel plate and strip samples. According to the comparison of the two methods, the relative difference between them is 0.27% for sample of g-o-material and 0.06% for that of n-o-material. The uncertainty of the two methods both are 0.31%. It can be stated that the two methods, the VDP and the traditional method, applied to strip samples, show excellent agreement and should be introduced both in the new edition of the IEC 60404-13 standard.
