This part is the 11th part of GB/T 2951.
This part is equivalent to IEC 60811-1-1.2001 "General test methods for insulation and sheathing materials for cables and cables - Part 1-1.
Test Method---Measurement of Thickness and Dimensions---Mechanical Properties Test" (English version).
Taking into account China's national conditions and ease of use, this section has made the following editorial changes.
--- Replace "Part 1-1" with "Part 11";
--- Replace the "," as a decimal point with a decimal point "."
--- Remove the preface to international standards;
--- This section 1.1 quotes the use of international standards of China's standards rather than international standards;
--- This part is added to the standard name of IEC 60811-1-1 in Chapters 1 and 3 of IEC 60811-1-1.
The "coax" has been added to the coordination of the cable.
