This Part 3-9 of EN 50289 details the methods of test to determine the bending tests used in analogue and digital communication systems to:-bending around a test mandrel (clause 4);-repeated bending (clause 5);-repeated flexing in service (clause 6);-flexing in service (clause 7);-bending around rollers or bows during installation (clause 8); and-measure the stiffness (clause 9) of such a cable;-kink test (clause 10).It is to be read in conjunction with Part 3-1 of EN 50289, which contains essential provisions for its application.
