本文件建立了有关成像材料、相关存储材料和数字存储介质永久性的术语和定义词汇表。 在大多数情况下，这些术语和定义是通用的，适用于整个成像行业。有关特定应用的术语和定义，请参阅行业标准。然而，在某些情况下，一个术语的定义仍在演变，并且/或者被不同的用户群体以不同的方式使用。在这种情况下，给出了一个适用于成像材料的定义——永久性工作，并对这种效果进行了说明。

This document establishes a vocabulary of terms and definitions used in respect of the permanence of imaging materials, related storage materials and digital storage media. In most cases these terms and definitions are generic and are applicable to the entire imaging industry. For terms and definitions specific to particular applications, refer to industry standards. However, in some cases the definition of a term is still evolving and/or is used by different user groups in different ways. In this case a definition fit for use in Imaging Materials – Permanence work is given and a note to this effect is included.
