scope:

This part of IEC 60794 is a family specification that covers optical self-supporting aerial telecommunication cables. Requirements of the sectional specification IEC 60794-3 for duct, buried and aerial cables are applicable to cables covered by this standard. Self-supporting aerial telecommunication cable in this context means a cable construction having sufficient strength members and designed to be suspended on poles and similar devices without the aid of another supporting wire or conductor. Clause 5 of this standard describes a blank detail specification for optical self-supporting aerial telecommunication cables. It incorporates some minimum requirements. Detail specifications may be prepared on the basis of this family specification. The parameters specified in this standard may be affected by measurement uncertainty arising either from measurement errors or calibration errors due to lack of suitable standards. Acceptance criteria should be interpreted with respect to this consideration (see IEC 60794-3 clause 9). The number of fibres tested is representative of the cable design and should be agreed between the user and the manufacturer.
