Automatic steam traps - Classification (ISO 6704:1982)

Establishes a simple classification of the main types according to the mode of actuation of their obturation device and disregarding their details of conception and construction. Three categories of steam traps can be distinguished: mechanical traps, actuated by the level of condensate; thermostatic traps, actuated by the temperature of the condensate; thermodynamic traps, actuated by fluid dynamics.

Foreword ISO (the International Organization for Standardization) is a worldwide federation of national Standards institutes (ISO member bodies). The work of developing Inter- national Standards is carried out through ISO technical committees. Every member body interested in a subject for which a technical committee has been set up has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISO Council. International Standard ISO 6704 was developed by Technical Committee ISO/TC 153, Valves, and was circulated to the member bodies in February 1980. lt has been approved by the member bodies of the following countries : Australia Austria Belgium Brazil Canada China Czechoslovakia Denmark Finland France Germany, F.
