0.    INTRODUCTION

       This specification provides the definition of the Dangerous
       goods recapitulation message (DGRECA) to be used in Electronic
       Data Interchange (EDI) between trading partners involved in
       administration, commerce and transport.

1.    SCOPE

1.1   Functional Definition

       A message to specify recapitulations pertaining to the
       dangerous goods on board of a means of transport, e.g. a
       vessel.

1.2   Field of Application

       The Dangerous goods recapitulation message may be used for both
       national and international applications. It is based on
       universal practice related to administration, commerce and
       transport, and is not dependent on the type of business or
       industry.

1.3   Principles

       The message has been designed to enable control of pollution
       caused by a means of transport, e.g. in the maritime and port
       environment.
       
       * The message relates to one means of transport.
       
       * The message contains summary information of all dangerous
       goods on board of the means of transport.
       
       * Summary information is given as a recapitulation across all
       consignments on board of the means of transport, for the
       dangerous goods that adhere to a certain combination of IMO
       code (i.e. International Maritime Organisation), IMO page
       number, UNDG number (i.e. United Nations Dangerous Goods
       number) and flashpoint.
       
       Business area: control of pollution by a means of transport
       (e.g. maritime pollution)
       
       Sending function: authority (e.g. port), centralised database
       of authorities
       
       Receiving function: authority, search and rescue organisation.
