(1) “Angle Control” A safety feature designed to prevent a tool from operating when tilted beyond a predetermined angle. (2) “Cased Power Load” A power load with the propellant contained in a closed case. (3) “Caseless Power Load” A power load with the propellant in solid form not requiring containment. (4) “Direct-Acting Tool” A tool in which the expanding gas of the power load acts directly on the fastener to be driven. (5) “Fixture” A special shield which provides equivalent protection where the standard shield cannot be used. (6) “Head” That portion of a fastener which extends above work surface after being properly driven. (7) “Indirect-Acting Tool” A tool in which the expanding gas of the power load acts directly on a captive piston which in turn drives the fastener. (8) “Misfire” A condition in which the powder load fails to ignite after the tool has been operated. (9) “Powder-Actuated Fastening System” A method comprising the use of a powder-actuated tool, a power load, and a fastener. (10) “Powder-Actuated Tool,” also known as “Tool” A tool that utilizes the expanding gases from a power load to drive a fastener. (11) “Test Velocity” A series of deliberately free-flighted fasteners whose velocities are measured 6-1/2 feet from the muzzle end of the tool using accepted ballistic test methods.
