取消并替换第一版（1988年）。指定将数据和控制信息从一个演示实体传输到对等演示实体的程序；通过功能单元选择展示实体使用的程序的方式；用于传输数据和控制信息的表示协议数据单元的结构和编码。这些程序适用于支持OSI参考模型表示层且希望在OSI环境中互连的系统之间的通信实例。还规定了实施这些程序的系统的一致性标准。 不包含可用于证明符合性的测试。

Cancels and replaces the first edition (1988). Specifies procedures for the transfer of data and control information from one presentation-entity to a peer presentation-entity; the means of selecting, by means of functional units, the procedures to be used by the presentation-entities; the structure and encoding of the presentation-protocol-data-units used for the transfer of data and control information. These procedures are applicable to instances of communication between systems which support the presentation layer of the OSI reference model and which wish to interconnect in an OSI environment. Also specifies conformance criteria for systems implementing these procedures. Not contains tests which can be used to demonstrate this conformance.
