Requirements regarding electronic records and signatures were published in the United States Federal Register 21 CFR Part 11 in August 1997. These requirements regulate the control of records and signatures and associated security issues in order to respond to the movement towards paperless systems. In the QC lab, printouts from analytical equipment are often treated as raw data and especially for analytical equipment which are computer controlled, where the output is received via electronic media, compliance with the requirements of 21 CFR Part 11 is required to assure the output results.
