== Distinguishing recalls from failures ==

Cylinder safety records describe several different events that should not be conflated.

'''Inspection rejection''' occurs when a cylinder is found unsuitable for continued service because of visible damage, internal corrosion or another defect.

'''Hydrostatic test failure''' occurs when a cylinder does not satisfy the requirements of the pressure test or associated requalification process.

'''Manufacturing non-compliance''' occurs when a cylinder has not been produced, inspected or tested according to its applicable approval.

'''Product recall or withdrawal''' is a corrective action affecting identified cylinders or production batches. A recall does not necessarily mean every affected cylinder is physically defective.

'''In-service failure''' involves an uncontrolled loss of pressure containment, leakage, structural rupture or failure of another component during operation.

Consequently, a cylinder may be recalled without ever having failed hydrostatic testing, while another may fail inspection without having been the subject of a manufacturer recall.
