NIST SP 951
A Guide to EU Standards and Conformity Assessment

Declaration of Incorporation

Annex II of the Machinery Directive lists the information that must appear in the Declaration of Conformity. It is the only directive that also calls for more than one type of Declaration. Machines that operate standing alone are covered by a Declaration of Conformity as described in Part A of Annex II. But, where the maker of a larger machine integrates or incorporates a subassembly, the manufacturer of the subassembly is required to issue a Declaration of Incorporation (Part B of Annex II).

The general principle behind a Declaration of Incorporation is that the manufacturer of a subassembly cannot be required to foresee all the ways the subassembly may be incorporated, and, more importantly, may not be able to provide all the safety aspects of the larger machine.

The Declaration of Incorporation includes a statement that protects the subassembly manufacturer, and transfers the responsibility for safe incorporation to the builder of the larger system. Annex II part B contains suggested language for this statement by the manufacturer of the subassembly: "This machinery may not be put into service until the machinery into which it is to be incorporated has been declared in conformity with the provisions of the Directive."
