标准范围

IEC 61753-111-07:20 21包含密封光纤封闭件需要满足的最低测试、测试严重性和测量要求，以便被归类为符合IEC 61753表A.13中定义的A类天线的IEC标准？1:2018.本文件不包括自由呼吸关闭。第一版取消并取代了2009年发布的IEC 61753-111-7。本版构成技术修订版。本版本包括以下与IEC 61753相关的重大技术变更？111？7:根据IEC 61753-1:20 18和IEC 61756-1:20 19更新术语和定义；增加了材料抗紫外线和抗真菌测试的详细测试严重性；根据IEC 61753-1:20 18更新测试严重性；密封试验的试验超压改为20 kPa；在机械密封试验中增加了试验过程中压力损失的通过-失败标准；除非另有规定，实验室测试条件符合IEC 61300-1至+23°C±5°C；根据IEC 61756-1:20 19，添加具有储存纤维最小弯曲半径的B-657纤维类型；振动密封试验改为10 Hz，振幅3 mm，循环次数1 000 000次；减少小直径电缆和管道的电缆保持试验中增加的载荷；减少小直径电缆和管道的电缆轴向压缩试验的载荷；增加了扭转和弯曲试验的循环持续时间；删除了自由落体测试（现在包含在光学冲击测试中）；组装和拆卸测试的持续时间减少到5个周期；温度变化的持续时间减少到12个循环。

IEC 61753-111-07:2021 contains the minimum tests, test severities and measurement requirements which a sealed fibre optic closure need to meet in order to be categorised as meeting the IEC standard for category A – Aerial, as defined in Table A.13 of IEC 61753？1:2018. Free breathing closures are not covered in this document. This first edition cancels and replaces IEC 61753-111-7 published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 61753？111？7:

1. terms and definitions updated according to IEC 61753-1:2018 and IEC 61756-1:2019;
2. detailed test severities added for UV light and fungus resistance tests of materials;
3. test severities updated according to IEC 61753-1:2018;
4. test overpressure for sealing tests changed to 20 kPa;
5. pass-fail criterion of pressure loss during test added to mechanical sealing tests;
6. laboratory test conditions harmonized with IEC 61300-1 to +23 °C ± 5 °C, unless otherwise specified;
7. addition of B-657 fibre types with minimum bending radius of stored fibres according to IEC 61756-1:2019;
8. vibration sealing test changed to 10 Hz, 3 mm amplitude and 1 000 000 cycles;
9. reduced loads added in cable retention test for small diameter cables and tubes;
10. reduced loads for cable axial compression test for small diameter cables and tubes;
11. duration of the cycles in torsion and bending test added;
12. free fall test removed (is covered now by the optical shock test);
13. duration of the assembly and disassembly test reduced to 5 cycles;
14. duration of the change of temperature reduced to 12 cycles.
