ISO 16100-4:2006 specifies the test method, the associated test criteria and the statement format used to evaluate and declare the degree of conformance of an implementation, i.e. a unit under test (UUT), to the requirements specified in other parts of ISO 16100.

ISO 16100-4:2006 includes definitions intended to assist a manufacturer or supplier (first party), a user or purchaser (second party), or an independent body (third party) to perform the assessment for type evaluation.

ISO 16100-4:2006 contains the following:

• an enumeration of those conformance aspects that can be used to determine whether an implementation conforms to ISO 16100;
• a definition of the conformance tests and statements used in declaring which aspects are met by an implementation;
• a description of the aspects to be included in a conformance statement;
• a set of rules to select valid or invalid combinations of aspects when they are combined.
