The Declaration of incorporation is the document supplied by the manufacturer of partly completed machinery. A window actuator on its own is usually such partly completed machinery: it only becomes a finished machine – the power-operated window – together with the window and the control.
What does the declaration of incorporation contain?
It names the manufacturer, the product and which essential safety requirements the actuator itself meets. It also states that the partly completed machinery may only be put into service once the finished machine meets the requirements. The assembly instructions belong to it.
What does this mean for window fabricators and installers?
Whoever assembles window, actuator and control is the manufacturer of the power-operated window. They carry out the Risk assessment for the complete window and files the declaration of incorporation and instructions of the actuators with the project documents.
