FinalCenter for Devices and Radiological Health05/01/1980

Description

This guideis intended to help manufacturers of high-intensity mercury vapor discharge lamps to establish adequate quality control and testing programs for compliance with the Federal performance standard for such lamps (21 GR 1040.30). It is intended as guidance and to define good manufacturing. practice in this area. Although, specific sampling plans are included in Section 4, other sampling plans could be used as long as they provide equal protection and assurance of compliance.
