Information technology - Generic cabling for customer premises - Part 9904: Assessment and mitigatio...
ISO/IEC TR 11801-9904:2017(E) This technical report provides guidance on whether installed Class D and Class E channels specified in ISO/IEC 11801:2002 will support 2,5GBASE-T and 5GBASE-T. It also provides mitigation procedures to improve the perfomance of Class D and Class E channels to the point where these applications are supported. Higher classes according to ISO/IEC 11801:2002 will support…

Guidelines for the statistical analysis of ageing test data - Part 3: Minimum specimen numbers at di...
IEC TR 60493-3:2017(E) clarifies how a statistical analysis can be done with a small number of samples.
This document will be useful when the accelerated test method is difficult to carry out, for example in cases where the dimensions of test specimens (including test devices) are very large in scale or the cost of test specimens is high. Testing is facilitated by enabling users to reduce the…
