The exception among the negotiators is Paul H. Nitze, who has reversed his earlier position that the treaty prohibits such testing.

In 1963, many countries ratified the Partial Test Ban Treaty which prohibited atmospheric nuclear testing.

Last week, the Senate voted, 58 to 38, to prohibit advanced testing and quicker development of the missile shield.

The original interpretation of this treaty, which was ratified, prohibits such testing.

This interpretation prohibits the development and testing needed for faster deployment.

The commission voted 6 to 3 to prohibit testing, either in job applications or when employers suspect a worker has a drug problem.

The agreement now prohibits nuclear testing in the atmosphere, in space or under the oceans.

The convention prohibits testing, production and development of biological agents for warfare purposes.

The rest of the children come from biological parents who are impoverished, putting them in a category under federal law that prohibits such testing.

New York State, meanwhile, prohibits testing, even for inmates requesting it, unless they show symptoms.
