IEC 62702-1-2:20 22作为IEC 62702-1-2:20 22 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 62702-1-2:20 22规定了一种用于长期数据存储的可写BD磁盘（以下简称“磁盘”）的数据质量保证方法，以及一种可以将记录数据维持在磁盘上以长期保存音频数据的数据迁移方法。可写盘包括BD可记录盘和BD可重写盘。IEC 62702-1-2:20 22取消并取代2016年发布的第一版。本版构成技术修订版。为了反映ISO/IEC 29121:2021的更新，此版本相对于上一版本包含以下重大技术变更:a)ISO/IEC 16963已被确定为估算寿命的参考试验方法； b)增加了测量最大数据误差的环境条件； c)考虑到用户的使用情况，改变了试驾要求； d)对估计寿命的要求得到了更明确的界定； e)更明确地定义了定期性能测试的要求。

IEC 62702-1-2:2022 is available as IEC 62702-1-2:2022 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 62702-1-2:2022 specifies a method of data-quality assurance for writable BD disks (hereafter referred to as "disks") which are specified for long-term data storage, and a data migration method which can sustain the recorded data on disks for long-term audio data preservation. The writable disks include BD recordable disk and BD rewritable disk. IEC 62702-1-2:2022 cancels and replaces the first edition published in 2016. This edition constitutes a technical revision. In order to reflect the updates to ISO/IEC 29121:2021, this edition includes the following significant technical changes with respect to the previous edition:
a) ISO/IEC 16963 has been identified as the referee test method for the estimation of lifetime;
b) the ambient conditions for the measurement of maximum data error have been added;
c) the requirements for test drives have been changed considering the use condition of users;
d) the requirements for the estimated lifetime have been defined more clearly;
e) the requirements for the periodic performance test have been defined more clearly.
