Amorphous and nanocrystalline alloys measurement methods—Part 1:AC magnetic properties by the use of ring specimens
全国钢标准化技术委员会(SAC/TC 183)
GB/T 19346的本部分规定了非晶纳米晶合金卷绕环形试样交流磁性能的测量方法。
本部分适用于测量各种变压器和电感类元器件以及磁屏蔽用的非晶纳米晶软磁合金在50 Hz ~ 200 kHz频率范围内的相对幅值磁导率、比总损耗、比视在功率等交流磁性能。如果有合适的经过校准的仪器，频率上限可延伸到1 MHz，但此时再现性应适当放宽要求。
