1 Scope
This part of ISO 6953 specifies which characteristics of compressed air pressure regulators are to be included in literature from their suppliers. It also applies to filter-regulators .
This part of ISO 6953 applies to
— manually controlled direct operated types (with or without relieving mechanism),
— manually controlled internal pilot operating types (e.g. nozzle flapper), and
— external pilot operated types.
In addition, it specifies the product marking requirements for pressure regulators and filter-regulators .
This part of ISO 6953 is applicable to compressed air pressure regulators with a rated inlet pressure of up to 2 500 kPa (25 bar) and an outlet adjustment pressure of up to 1 600 kPa (16 bar); and to filter-regulators with rated inlet and outlet pressures of up to 1 600 kPa (16 bar), in which the major contaminants are removed by mechanical means.
NOTE 1 1 bar = 0,1 MPa = 10 5 Pa; 1 MPa = 1 N/mm 2 .
The rated pressure should be selected from the preferred pressures listed in ISO 2944.
