1 Scope

This part of GB/T 17737 applies to coaxial communication cables. It specifies the test method to determine the bending performance of the cable.

--- bending around the rod (Chapter 4);

--- Repeated bending (Chapter 5);

--- Flexing (Chapter 6);

--- Bending durability (Chapter 7);

--- Tensile Bending (Dynamic Test) (Chapter 8);

--- Stiffness (Chapter 9);

--- Kink (Chapter 10).
