1范围本国际标准参考其他规范。这是通过参考ISO/IEC 9804中定义的CCR服务在此类规范范围内完成的。对CCR服务的引用会调用本国际标准的程序，以产生外部影响。当CCR服务的使用不包括任何直接或间接使用ISO 8326中定义的会话活动管理服务的通信活动时，本国际标准适用。它可以在会话活动内部使用，也可以在会话活动功能单元未使用的会话连接上使用。 当通过附录B的机制使用S-ACTIVITY服务时，也可以使用该标准。本国际标准规定了实施这些程序的系统的静态和动态一致性要求。它不包含可用于证明符合率的测试。

1ScopeThis International Standard is to be applied by reference from other specifications. This is done within such specifications by reference to the CCR services defined in ISO/IEC 9804. A reference to a CCR service invokes the procedures of this International Standard to cause external effects.This International Standard applies whenever the use of CCR services does not encompass any communication activity which makes direct or indirect use of the session activity management services defined in ISO 8326. It can be used inside a session activity, and on a session-connection where the session activity functional unit is not in use. It can also be applied when the S-ACTIVITY service is used through the mechanisms of annex B.This International Standard specifies the static and dynamic conformance requirements for systems implementing these procedures. It does not contain tests which can be used to demonst rate conformance.
