IEC 60794-208:2025 describes test procedures to be used in establishing uniform requirements for optical fibre cables for the pneumatic resistance environmental property, for unfilled cables which are protected by gas pressurization. This document applies to optical fibre cables for use with telecommunication equipment and devices employing similar techniques, and to cables having a combination of both optical fibres and electrical conductors. NOTE Throughout the document, the wording "optical cable" can also include optical fibre units, microduct fibre units, etc.
This first edition of IEC 60794‑1‑208 cancels and replaces method F8 of the second edition of IEC 60794‑1‑22 published in 2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) the form of the formula for pneumatic resistance is modified for ease of calculation with test pressures other than 62 kPa;
b) details to be reported are added.
The content of the corrigendum 1 (2025-12) has been included in this copy.
