给出了安装在机场照明和信标用串联系统一次电路中的屏蔽或非屏蔽单芯电缆的结构、尺寸和试验要求。它不适用于带有模制连接器的主电缆。 本规范不考虑电缆在火灾情况下的特殊性能。如果需要此类特殊性能（火焰传播、烟雾排放和烟气的酸性/腐蚀性），则应采用此处未提及的相关国际标准。 此外，如果客户要求，电缆还可以符合本规范中未包含的特殊要求。制造商和客户应就任何附加测试或尺寸修改达成一致。 本规范考虑了一次电路的特殊条件，并尽可能符合IEC 60502-2中包含的规范。

Gives the construction, dimensions and test requirements of screened or unscreened single core cable to be installed in the primary circuits of series systems for lighting and beaconing of airports. It does not apply to primary cables with connectors moulded to them. This specification does not consider special performance of cables in case of fire. If such special performance (flame propagation, smoke emission and acidity/corrosivity of fumes) is required, relevant International Standards not mentioned here should be applied. The cables can, additionally, be subjected to particular requirements not included in this specification, if requested by the customer. Any additional tests or modification of dimensions should be agreed between the manufacturer and the customer. This specification takes into account the particular conditions of primary circuits and, as far as possible, is in line with the specifications contained in IEC 60502-2.
