For the purposes of this document, the terms and definitions given in The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments and errata) applies. OPC 10000-1, OPC 10000-2, OPC 10000-3, OPC 10000-4, OPC 10000-6, and OPC 10000-8 as well as the following apply. An overview of the terms defined in this standard and their interaction can be viewed in Figure 1.

a software program that executes or implements some aspect of OPC UA

Note 1 to entry: The application could run on any machine and perform any function. The application could be software or it could be a hardware application, the only requirement is that it implements OPC UA.

a specific set of OPC UA features that can be tested as a single entity

Note 1 to entry: A ConformanceUnit can cover a group of services, portions of services or information models.

a group of ConformanceUnits that is given a name

Note 1 to entry: This grouping is only to assist in organizing ConformanceUnits. Typical ConformanceGroups include groups for each of the service sets in OPC UA and each of the Information Model standards.

a Profile dedicated to a specific feature that a Server or Client may require

Note 1 to entry: Facets are typically combined to form higher-level Profiles. The use of the term Facet in the title of a Profile indicates that the given Profile is not a standalone Profile.

a Profile that defines all features necessary to build a functional OPC UA Application

Note 1 to entry: A FullFeatured Profile in particular adds definitions of the transport and security requirements.

arranges Profiles into application classes, such as Server or Client

Note 1 to entry: These categories help determine the type of Application that a given Profile would be used for. For additional details see 4.4.

a technical description of a set of steps required to test a particular function or information model

Note 1 to entry: TestCases provide sufficient details to allow a developer to implement them in code. TestCases also provide a detailed summary of the expected result(s) from the execution of the implemented code and any precondition(s) that must be established before the TestCase can be executed.

a facility that is designated to provide testing services

Note 1 to entry: These services include but are not limited to personal that directly perform testing, automated testing and a formal repeatable process. The OPC Foundation has provided detailed standard describing OPC UA TestLabs and the testing they are to provided (see Compliance Part 8 UA Server, Compliance Part 9 UA Client).
