Foreword
This document was drafted in accordance with the provisions of GB/T 1.1-2020
“Directives for standardization - Part 1: Rules for the structure and drafting of
standardizing documents”.
This document replaces GB/T 11091-2014 “Copper strip for cables”. Compared with
GB/T 11091-2014, in addition to structural adjustments and editorial changes, the main
technical changes are as follows:
a) MODIFY the scope of the standard, from “applies to copper strips for making
communication cable products” to “applies to copper strips and foils for making
cable products” (see Clause 1 of this document, Clause 1 of the 2014 edition);
b) ADD the term of unevenness and its definition (see 3.1 of this document);
c) ADD the “TP2” designation and its code “C12200” (see 4.1 of this document);
d) ADD three status of designation TP2, i.e. “annealed, 1/4 hard, 1/2 hard” (see 4.1
of this document);
e) MODIFY the thickness range, from “0.07 mm ~ 0.80 mm” to “0.05 mm ~ 1.50
mm” (see 4.1 of this document, 3.1.1 of the 2014 edition);
f) MODIFY the width range, from “15 mm ~ 305 mm” to “10 mm ~ 305 mm” (see
4.1 of this document, 3.1.1 of the 2014 edition);
g) ADD the thickness allowable deviation of the thickness of 0.05 mm ~ < 0.07 mm
and > 0.8 mm ~ 1.5 mm (see 5.2.1 of this document);
h) ADD the relevant provisions for edge burs (see 5.2.4 of this document);
i) MODIFY the unevenness of any two layers, from “the unevenness of any two
layers shall not exceed 5 mm” to “the unevenness of any two layers shall not
exceed 1.0 mm for the thickness of 0.1 mm and below, and shall not exceed 2.0
mm for the thickness of 0.1 mm and above” (see 5.2.5 of this document, 3.3.4 of
the 2014 edition);
j) ADD the mechanical properties of designation TP2 at the status of “annealed, 1/4
hard, 1/2 hard”; ADD the hardness requirements for designations T2 and TP1 at
the status of “O81” (see 5.3 of this document);
k) ADD the provisions for the elongation after fracture, A50 mm, of foils with a
thickness of not more than 0.10 mm (see 5.3 of this document);
