The 'Treaty Banning Nuclear Weapon Tests In The Atmosphere, In Outer Space And Under Water', often abbreviated as the 'Partial Test Ban Treaty' ('PTBT'), 'Limited Test Ban Treaty' ('LTBT'), or 'Nuclear Test Ban Treaty' ('NTBT') (although the latter also refers to the Comprehensive Test Ban Treaty) is a treaty prohibiting all test detonations of nuclear weapons except underground. It was developed both to slow the arms race (nuclear testing is necessary for continued nuclear weapon advancements), and to stop the excessive release of nuclear fallout into the planet's atmosphere.
It was opened for signature on August 5 1963, and entered into force on October 10 1963.
