Office and Postal Address: Tolerances on dimensions and ieo Status: This is in contrast to EN which was referred to in EN and allowed some areas to be below minimum thickness.
It is quite difficult to compare the flatness tolerances in EN and ISOas the definition of steel types is totally different. There are two levels of tolerance normal Class N and special Class S. Learn more about the cookies we use io how to change your settings.
It can be argued that neither standard is completely consistent on this subject. Even the nitrogen strengthened steels were in this type. One interpretation of the standard is that no ground area of the plate may fall below the minimum thickness tolerance.
