The organization had been started in 1920s as the International Federation of the National Standardizing Associations (ISA). But in 1942 during World War 2 It was out of the role. be that as it may, after the war ISA was drawn closer by the as of late framed United Nations Standards Coordinating Committee (UNSCC) with a proposition to shape another worldwide norm body. In October 1946, ISA and UNSCC delegates from 25 nations met in London and consented to unite to make the new International Organization for Standardization. The new association authoritatively started activities in February 1947.
