IEC 60227-7:1995/AMD2:2011 标准是聚氯乙烯绝缘电缆的国际标准，适用于额定电压为450/750V的屏蔽和非屏蔽柔性电缆，两个或多个导体。该标准规定了电缆的要求，包括导体、绝缘、护套、屏蔽和标记等方面。

该标准要求电缆的导体采用铜或铜合金制成，导体的截面积应符合标准要求。绝缘材料应为聚氯乙烯，其厚度应符合标准要求。电缆的护套材料应为聚氯乙烯或聚氨酯，其厚度应符合标准要求。屏蔽材料应为铝箔或铜网，其覆盖率应符合标准要求。电缆的标记应包括电缆型号、额定电压、制造商名称和生产日期等信息。

该标准还规定了电缆的试验方法，包括导体电阻、绝缘电阻、耐电压、屏蔽效能、机械性能和燃烧性能等方面的试验。电缆应符合标准要求才能出厂销售。

IEC 60227-7:1995/AMD2:2011 标准适用于在固定安装或移动设备中使用的电缆，如电力设备、通信设备、控制设备等。该标准的实施可以保证电缆的质量和安全性能，有助于保障设备的正常运行和人身安全。
