GB/T 30540-2014 in English

《GB/T 30540-2014文件管理应用 电子数据的存档 计算机输出缩微品（COM）/计算机输出激光光盘（COLD）》由TC86（全国文献影像技术标准化技术委员会）归口，TC86SC1（全国文献影像技术标准化技术委员会质量分会）执行，主管部门为国家标准化管理委员会。
本标准规定了为长期确保电子数据的完整性、可存取性、可用性、可读性和可靠性而将其存档的技术,以便保护数据的证据价值。在本标准中,长期的含义是延续100年以上的时间(见GB/T18444―2001)。本标准使用化学药液处理的黑白缩微品。之所以选择该方法,是因为其结果总是不可逆转的记录,而且作为长期保存的介质,缩微品的质量是经过验证的。本标准还规定了由一个制作单位从同样数据并行记录COM 和COLD输出的方法。本标准适用于多种不同类型的电子数据,诸如文本数据和能够以黑白影像表达的二维图形数据。本标准不适用于:―――动画影像或声音;―――三维影像;―――灰度或彩色影像;―――X射线影像。热法处理生成的缩微品由于在不可更改性和长期性方面没有提供足够的保证,所以这样的缩微品不包括在本标准的范围内。

Scope

This International Standard specifies techniques for archiving electronic data to ensure their integrity, accessibility, usability, readability and reliability over time, in order to protect the evidentiary value of the data. In this standard, the meaning of long-term is to last for more than 100 years (see GB/T 18444-2001). This standard uses black and white microforms processed with chemical liquid. This method was chosen because the results are always irreversible records and the quality of the microforms is proven as a medium for long-term preservation. This standard also specifies methods for recording COM and COLD outputs in parallel from the same data by one production unit. This standard applies to many different types of electronic data, such as text data and two-dimensional graphic data that can be expressed in black and white images. This standard does not apply to: - animated images or sound; - three-dimensional images; - grayscale or color images; - X-ray images. Microforms produced by heat treatment are not included in the scope of this standard because they do not provide sufficient guarantees of inalterability and long-term durability.
