How do you check? The FCC only requires that you test it yourself and file the results in a drawer. Nothing is submitted to any approval agency. If there is a complaint they come and check your files.
And there are two levels of checking. Industrial use, which is more lax, and consumer use, which is strict. I don't know what a module would require. Maybe nothing since it is always part of a product and the product is what matters.
