IEC？60404-8-11:20 18定义了semi中交付的铁基非晶带材的等级？标称厚度为0.025 mm的加工状态，即未经最终热处理。从0,020毫米到0,030毫米范围内的其他标称厚度可由制造商和买方在询价和订购时达成协议。特别是，它给出了一般要求、磁性、几何特性、公差和工艺特性，以及检验程序。 本文件适用于以具有铸态边缘的线圈形式提供并用于构建磁路的快速凝固铁基非晶带材。 成绩分为两类: -常规等级； -高渗透等级。 它们对应于IEC的I1级？60404-1.

IEC？60404-8-11:2018 defines the grades of Fe-based amorphous strip delivered in the semi？processed state, i.e. without final heat treatment, of nominal thickness 0,025 mm. Other nominal thicknesses in the range from 0,020 mm to 0,030 mm can be specified by agreement between the manufacturer and the purchaser at the time of enquiry and order. In particular, it gives general requirements, magnetic properties, geometric characteristics, tolerances and technological characteristics, as well as inspection procedures.
This document applies to the rapidly-solidified Fe-based amorphous strip supplied in coils with as-cast edges and intended for the construction of magnetic circuits.
The grades are grouped into two classes:
- conventional grades;
- high permeability grades.
They correspond to Class I1 of IEC？60404-1.
