Well...there are SOME specifications. I don't have my COM book with me but there are at least two interfaces (=methods) that are required to be COM-compliant (iAdviseSink, iUnknown) and, I believe, that a COM-compliant object cannot directly expose properties to external change. Also, interfaces can never be changed nor deleted. New versions must expose new interfaces.
