IEC 62702-1-2:20 22 RLV包含官方IEC国际标准及其红线版本。Redline版本仅提供英文版本，为您提供了一种快速简单的方法来比较IEC官方标准与其以前版本之间的所有变化。 IEC 62702-1-2:20 22规定了用于指定用于长期数据存储的可写BD盘(以下称为“盘”)的数据质量保证方法，以及可以将记录的数据维持在盘上以用于长期音频数据保存的数据迁移方法。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的更新:2021年，该版本相对于上一版本包括以下重大技术变更: 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 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its 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.
