[中文适用范围]： IEC 62087的本部分规定了带有可移动介质的视频记录设备的功耗测量方法。它指定了与测量功耗相关的不同操作模式。测量方法仅适用于可连接至电源的设备。本标准中的测量条件代表设备的正常使用，可能与安全标准中指定的特定条件@不同。 [外文原描述]： IEC 62087-4:2015 specifies methods of measurement for the power consumption of video recording equipment with removable media. It specifies the different modes of operation which are relevant for measuring power consumption. This first edition of IEC 62087-4 cancels and replaces Clause 7 of IEC 62087:2011. This standard together with IEC 62087-1 to IEC 62087-3 and IEC 62087-5 to IEC 62087-6 cancels and replaces IEC 62087:2011. This International Standard constitutes a technical revision. This edition includes significant technical changes with respect to Clause 7 of IEC 62087:2011. The changes include fundamental and extensive revisions to cover video recorders such as DVD and BD types as well as recorders with removable solid state memory. Clause 7 has been revised in its entirety.
