IEC 61300-2-10:20 21作为IEC 61300-2-10:20 21 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 61300-2-10:20 21评估了当光纤设备暴露在危急情况下可能发生的负载影响，例如被踩踏、被车辆轮胎碾过、当均匀分布的静态负载施加到街道机柜的顶部表面或当负载施加到街道机柜的打开门时。这第三版取消并取代了2012年出版的第二版。与上一版相比，此版本包括以下重大技术变更: -增加测试施加在街柜的顶表面上的均匀分布的静态载荷；-增加测试施加到街柜门的静态负载； -增加了在标准大气条件中规定的其他指定温度下进行测试的描述，并增加了表1中的测试温度； -根据IEC 61753-1:20 18更新严重性。

IEC 61300-2-10:2021 is available as IEC 61300-2-10:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 61300-2-10:2021 evaluates the effect of loads which is possible to occur when fibre optic devices are exposed to critical situations such as being stepped on, being run over by vehicle tyres, when an evenly-distributed static load is applied to the top surface of a street cabinet or when a load is applied to a street cabinet's open door. This third edition cancels and replaces the second edition published in 2012. This edition includes the following significant technical changes with respect to the previous edition:
- addition of testing an evenly distributed static load applied on the top surface of a street cabinet;
- addition of testing a static load applied to a street cabinet door;
- addition of descriptions to perform the test at a specified temperature other as specified in the standard atmospheric conditions and addition of test temperature(s) in Table 1;
- update of the severities according to IEC 61753-1:2018.
