An implementation that conforms to one of the SOP Classes of the Study Root SOP Class Group shall support queries against the Query/Retrieve Information Model described in Section C.6.2.1 using the C-FIND SCU behavior described in Section C.4.1.2.

An implementation that conforms to one of the SOP Classes of the Study Root SOP Class Group as an SCU shall state in its Conformance Statement whether it supports Optional Keys. If it supports Optional Keys, then it shall list the Optional Keys that it supports.

An implementation that conforms to one of the SOP Classes of the Study Root SOP Class Group as an SCU shall be capable of generating queries using the Hierarchical Search. It shall not generate queries using Relational-queries unless the Relational-queries option has been successfully negotiated.

An implementation that conforms to one of the SOP Classes of the Study Root SOP Class Group as an SCU shall state in its Conformance Statement whether it may generate Relational-queries. If it supports Relational Search, then it shall also support Extended Negotiation of relational-queries as an SCU.

An implementation that conforms to one of the SOP Classes of the Study Root SOP Class Group as an SCU shall state in its Conformance Statement whether or not it supports Extended Negotiation of combined date-time matching, fuzzy semantic matching of person names, Empty Value Matching, and/or Multiple Value Matching.

An implementation that conforms to one of the SOP Classes of the Study Root SOP Class Group as an SCU shall state in its Conformance Statement how it makes use of Specific Character Set (0008,0005) and Timezone Offset From UTC (0008,0201) when encoding queries and interpreting responses.

An implementation that conforms to one of the SOP Classes of the Study Root SOP Class Group as an SCU shall support transfers against the Query/Retrieve Information Model described in Section C.6.2.1 using the C-MOVE SCU Behavior described in Section C.4.2.2.

An implementation that conforms to one of the SOP Classes of the Study Root SOP Class Group as an SCU shall support retrievals against the Query/Retrieve Information Model described in Section C.6.2.1 using the C-GET SCU Behavior described in Section C.4.3.2.

An implementation that conforms to one of the SOP Classes of the Study Root SOP Class Group as an SCU, which generates retrievals using the C-GET operation shall state in its Conformance Statement the Storage Service Class SOP Classes under which it shall support the C-STORE sub-operations generated by the C-GET.
