IEC 60794-1-127: 2026 defines the test procedures used to establish uniform requirements for mechanical performance – Indoor simulated installation test. It 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. Throughout this document the wording “optical cable” can also include optical fibre units, microduct fibre units, etc. This first edition cancels and replaces Method E27 of the first edition of IEC 60794-1-21 published in 2015, and its Amendment 1:2020. It constitutes a technical revision. This edition includes the following significant technical changes with respect to Method E27 of IEC 60794-1-21:2015, and 60794-1-21:2015/AMD1:2020: a) addition of a new Clause “11 Details to be reported.”
