Can anyone please tell me what you call it when you don't meet the conditions of a law and therefore can't use it

To put it in context

The second law of thermodynamics is an expression of the tendency that over time, differences in temperature, pressure, and chemical potential equilibrate in an isolated physical system

Expressly I am not saying the law is violated or anything I am trying to describe the periods when you are outside the law because like in the law above

You haven't had enough time to reach equilibrium or the physical system is not isolated.

The joys of trying to work across languages.

I wanted to call it a local violation but the very use of the word violation seems to get people upset.

Anyone able to help with what those periods are called?
