How Should You Use stringent?

Words that are synonymous with stringent include rigid, which implies uncompromising inflexibility ("rigid rules of conduct"), and rigorous, which suggests hardship and difficulty ("the rigorous training of firefighters"). Also closely related is strict, which emphasizes undeviating conformity to rules, standards, or requirements ("strict enforcement of the law"). Stringent usually involves severe, tight restrictions or limitations ("the college has stringent admissions rules"). That's logical.
