foreign materials or the continuous visible oxidation.
5.4.2 The surface of the strips is allowed to have pinholes not larger than 1.0
mm in diameter but not more than 1 per square centimeter.
5.4.3 The strips shall be smooth; there shall be no slivers, burrs, potholes,
wrinkles, folds or other defects affect the use. The edge of the strips shall have
no visible cracks and burrs.
5.5 Shear adaptability
When using suitable equipment for cutting, any part of the strips shall be able
to be cut into the usual shape.
6 Technical requirements
6.1 Physical properties
6.1.1 The strips delivered in the semi-processed state (prepared state) shall
be heat-treated properly to obtain the desired magnetic properties. But the
magnetic properties of the strips and related to the sampling and sample
preparation methods, sample shape and size, sample heat treatment system
and measurement methods and other factors. Therefore, when the supplier
supplies the data of magnetic properties of the strips, it shall indicate the sample
shape and size, sample heat treatment system, measurement method,
measurement equipment and measurement conditions.
NOTE. The final heat treatment of the strips is usually performed by the purchaser after the strip is
processed into the iron core. Therefore, the purchaser shall determine the best heat treatment syst...
