Intent.¹ The intent of this test is to establish the ability of a fiber optic cable (or fiber optic cable component, when appropriate) to mechanically withstand twisting.

Measurements. The following parameters may be measured or observed:

(a) The number of broken fibers caused by twisting.

(b) Any change in the outer covering.

(c) The change in optical measurement results caused by twisting.
