CGA P-81 – Standard for Microbulk Liquid Nitrogen Supply Systems, First Edition

CGA P-81 provides a standard for microbulk liquid nitrogen supply systems. It contains minimum requirements and recommended practices for the design, construction, installation, operation, and maintenance of microbulk liquid nitrogen supply systems from the fill connection to the nitrogen discharge liquid and gas use outlet. This standard does not cover the use of portable tanks built to U.S. Department of Transportation (DOT) standards.

While this publication is to be used as a standard for user installations, final approval of the design, equipment, appurtenances, and installation rests with the authority having jurisdiction.
