Both national and local governments have been paying great attention to the work of industrial standardization with the enormous increase in international trade after China joined WTO. According to the standards revising plan of Standardization Administration Committee of China (SAC),TC54 has already revised a series of national standards and industrial standards for foundry operations,and proposed some new ones. As a result,some old fashioned standards containing low-level techniques have been gradually discontinued or replaced with new versions.……展开更多
