Before the 1990s, the ASME had numerous test codes for individual components, such as gas turbines (PTC 22) and steam turbines (PTC 6), but no standard existed for determining the combined performance of an entire power generation facility. Recognizing this gap, the ASME Board on Performance Test Codes approved the formation of the PTC 46 Committee in June 1991. After several years of development involving manufacturers, users, and other experts, ASME PTC 46-1996, "Performance Test Code on Overall Plant Performance," was issued in October 1997. This new code filled a critical industry need, establishing itself as the go-to standard for combined cycle and other thermal plant testing. The standard was subsequently revised, with the current active edition being , officially reaffirmed in 2025.
