Explanation:
The treaty was signed in 1963 to ban the test of Nuclear Weapon Tests in under water, outer space and atmosphere. It also banned all nuclear detonations except those conducted underground.
Further Explanation:
Partial Test ban treaty is the short form of Treaty Banning Nuclear Weapon Tests in the Atmosphere, in Outer Space and Under Water. It prohibited the detonation of the nuclear weapons except the underground explosions. It is called LTBT(Limited Test Ban Treaty).
Initial negotiations for the treaty included complete ban, but it was changed due to the technical questions about the inability to detect underground tests. The stimulus specified to the test-ban was given by the increasing public fear over the immensity of nuclear tests, especially of thermonuclear weapons. The ban on nuclear tests was believed to be the only way to slow down the spread of nuclear weapons and arms race. The treaty did not stop the spread of nuclear arms. The amount of radioactive elements present around the atmosphere declined after this treaty.
United States Soviet Union and United Kingdom singed on it on 5th August 1963 and later it was opened for other countries who wanted to become a signatory.
The treaty declared that its aim was to achieve an agreement on complete disarmament of nuclear weapons. The treaty forbids the signatories from conducting nuclear detonations. It also prohibited peaceful nuclear explosions as it was difficult to differentiate it from the military tests.
By April 1964 more than 100 states had signed the treaty and 39 had passed it. And by 2015, 126 states had signed it, ten countries has signed but not put down the instruments of ratification. And Sixty states had not signed the PTBT.
