scope:

The purpose of this pamphlet is to set forth performance/selection criteria that should be utilized in identifying dual valve systems for bulk chlorine transportation applications (i.e. tank cars, cargo tanks and barges) after publication of this pamphlet. These configurations are intended to meet U.S. Department of Transportation (DOT) and Transport Canada (TC) performance requirements. This pamphlet contains information pertaining to standardizations, performance and design criteria as well as an appendix that includes information on valves/fittings and arrangements that meet these criteria.
