Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 4012-1983 "2.6/9.5mm coaxial cable integrated communications," compared with the GB/T 4012-1983, in addition to
Editorial changes, the main changes are as follows.
--- Increase the requirements for the conductive material should be consistent with GB/T 3953-2009 regulations (see 5.1,6.1,7.1,8.1,9.1);
--- Increased requirements for insulation materials should be consistent with YD/T 760-1995 provisions (see 5.2,6.2,7.2,8.2,9.2);
--- Increased soft copper wire, it should be consistent with the standard GB/T 3953-2009 (see Chapter 6);
--- Revised test methods conductive core diameter (see table 11, 1983 Edition Table 11);
--- Modify the terminal impedance and impedance irregularities test methods (see Table 11, the 1983 edition of the Table 11);
--- Revised test methods for working capacitance (see table 11, 1983 Edition Table 11);
--- Modify the attenuation constant of the coaxial test methods (see Table 11, the 1983 edition of the Table 11);
--- Revised test methods for the attenuation constant work line pairs (see Table 11, the 1983 edition of the Table 11);
--- Modify the crosstalk test methods (see Table 11, the 1983 edition of the Table 11);
--- Revised test methods capacitive coupling (see table 11, 1983 Edition Table 11);
--- Revised test methods on the ground capacitance unbalance (see table 11, 1983 Edition Table 11);
--- Test Method for increasing the shielding factor (see Table 11);
--- Modified outer sheath acceptance rules (see table 11, 1983 Edition Table 11);
--- Modify the provisions of the cable drum (see 17.1, 16.1, 1983 edition).
