These devices contain both a means of sensing seismic activity and a way of shutting off the flow of gas. Applicable to systems carrying natural gas and propane, the devices are used in piping, equipment, and the appliances typically found in structures of three stories or less. Topics include: An overview of applicability, operation, marking, and warranty for these devices; Construction issues, such as equipment and data to be provided by the manufacturer, corrosion and chemical resistance, instructions, and continued operation; Performance issues, including rigidity of mounting, deflection limits, test specimens, ruggedness, performance requirements, and durability; Definitions and references; and Detailed commentary with explanatory and supplementary information. The seismic performance requirements established in this standard are based on dynamic testing of current devices and in-depth examination of data on ground motions, structural damage, fire initiation, and actuation of existing earthquake shutoff devices. This new edition, which updates the previous Standard ANSI/ASCE/SEI 25-06, provides greater transparency regarding the performance of these devices. Standard ANSI/ASCE/SEI 25-16 is a primary reference for structural and mechanical engineers incorporating gas shutoff devices and systems into a design. It also will be of interest to manufacturers, inspectors, insurers, and owners in seismically active areas. 606 $aGas appliances$xStandards$zUnited States 606 $aEarthquakes$xSafety measures 610 0$aEarthquakes 610 0$aAutomation and robotics 610 0$aStandards and codes 610 0$aSeismic tests 610 0$aConstruction equipment 610 0$aSeismic effects 610 0$aGas flow 610 0$aTerminology and definition 615 0$aGas appliances$xStandards 615 0$aEarthquakes$xSafety measures. 676 $a683/.88 712 02$aAmerican Society of Civil Engineers, 801 0$bAmerican Society of Civil Engineers 801 1$bAmerican Society of Civil Engineers 906 $aBOOK 912 $a9910157804003321 996 $aEarthquake-Actuated Automatic Gas Shutoff Devices (ANSI$92833186 997 $aUNINA
