12、n and the need to assure a reliable supply of energy became important public concerns in the 1970s,the Board on Perform-ance Test Codes began to explore the possibility of addressing these concerns within the test code framework.As a result of these discussions,the PTC 40 Committee on Flue Gas Desul
13、furization units was organized in 1978;it held its first meeting in April 1979.The Committee faced considerable initial obstacles:there were no ASME PTC documents in this area,the technology was in the early stages of rapid development,and the boundary of the FGD equipment is to some extent a matter
14、 of definition.Nevertheless,in the next several years the PTC 40 Committee gradually evolved a systematic testing procedure for FGD units.The PTC 40 code draft was approved by the Board on Performance Test Codes on May 11,1990.The Code was adopted by the American National Standards Institute as an A
