IEC 60794-1-215:2020定义了用于建立环境性能统一要求的测试程序 -与采用类似技术的电信设备和装置一起使用的光纤电缆，以及 -具有光纤和电导体的组合的电缆。 贯穿本文件，措辞“光缆”还可以包括光纤单元、微导管光纤单元等。本文件定义了一个测试标准，通过观察护套物理外观或测量的电缆光衰减的任何变化来确定电缆承受可能立即包围光纤电缆护套的冻结水的影响的能力。方法F15A是模拟埋地电缆周围介质冻结的测试标准，如在潮湿的土壤或水中。方法F15A移自IEC 60794-1-22:20 17中的方法F15，无任何技术变更。方法F15B是模拟由刚性材料（例如钢）制成的刚性导管（管道）中外部电缆周围的介质冻结的测试标准。方法F15B包括防止电缆在刚性导管（管道）中经历冻结条件时被压碎的解决方案，其是压力吸收垫和任何其他建议的电缆保护装置。所有类型测试方法以及一般要求的参考指南可在IEC 60794-1-2中找到。

IEC 60794-1-215:2020 defines test procedures to be used in establishing uniform requirements for the environmental performance of
- optical fibre cables for use with telecommunication equipment and devices employing similar techniques, and
- 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 document defines a test standard to determine the ability of a cable to withstand the effects of freezing water that can immediately surround the optical fibre cable sheath by observing any changes in the physical appearance of the sheath, or in the measured cable optical attenuation. Method F15A is a test standard to simulate freezing of the medium surrounding a buried cable, as in wet earth or water. Method F15A is moved from method F15 in IEC 60794-1-22:2017 without any technical changes. Method F15B is a test standard to simulate freezing of the medium surrounding an outside cable in a rigid conduit (duct) which is made of rigid material, for example steel. Method F15B includes the solution to prevent the cable from being crushed when experiencing freezing conditions in a rigid conduit (duct) which are pressure absorber pads and any other suggested means of cable protection. A reference guide to test methods of all types as well as general requirements can be found in IEC 60794-1-2.
