It was formed in 1947 to develop specifications for connections with high-strength bolts. At that time, high-strength structural steel rivets were common in buildings and bridges, but bolts were expected to be safer, quicker, and more economical if technical equivalence could be demonstrated. The council's first ''Specification'' identified
