Dark matter stands outside that. It's not interacting through those forces. When we look at the world around us, we don't usually see the effects of dark matter because there's so much of it that we do, and it doesn't have those forces that we know about. But the standard model has worked spectacularly well. It's been tested to a high degree of precision. People are still testing it.
