including multiple and repetitive extensions of applied torque requirements, measured in units of inch-pounds
(avoirdupois) or Newton-Meters.
“A” diameter: Diameter of bottle around which pilfer proof or tamper evident band is applied.
bottle control: Equipment parts used for supporting and indexing bottles through a machine.
bottle finish: Sealing surface, threads, neck, neck ring or support ring of bottle.
bottle neck: The throat area below and including the thread finish of the bottle.
bridge torque: Same as secondary Torque.
calibration: The test performed to verify that actual test measurements coincide with certifiable standards or
conform to specifications.
cap feed: Parts or units, which relate to closure transfer or orientation.
cap release: Capper component, which allows bottle pick up of closure.
