Overview
This Amendment has become necessary as the requirements in subclause 4.2.2 relating to the tolerances on diameter and out-of-roundness of steel service pipes have been rendered more precise and Annex C "Calculated Continuous Operating Temperature (CCOT)" has been revised.
Please get in touch with the relevant contact person at DIN if you have problems understanding the content of the standard or need advice on how to apply it.
