Design specification for sealing and purging of instrument and tubing in petrochemical industry
This European Standard gives requirements for the types of industrial trucks specified in the scope of EN ISO 3691-5. This European Standard is intended to be used in conjunction with EN ISO 3691-5. These requirements are supplementary to those stated in EN ISO 3691-5 with the addition of the following hazards: Electromagnetic compatibility (EMC); when operating in potentially explosive atmospheres. This European standard partially replaces the following requirements of EN ISO 3691-5: Electrical requirements. This European standard defines supplementary requirements to EN ISO 3691-5: protection against crushing, shearing and trapping; information for use (instruction handbook and marking). Annex A (informative) contains the list of significant hazards covered by this standard.

This standard describes the various classes of cold-water trubine meters in sizes 3/4 in.(20mm)through 20 in.(500mm)for water supply customer service, mainline metering, and custody transfer of water among purveyors, and the materials and workmanship employed in their fabrication. The turbine meters described in this standard are divided into class Ⅰ and classⅡ meters. Both classes of meters register by recording the revolutions of a turbine set in motion by the force of flowing water striking its blades. Class Ⅰ. Class Ⅰ meters are the vertical-shaft and low-velocity, horizontal-shaft models. Class Ⅱ. Class Ⅱ meters are the in-line, horizontal-axis, high-velocity-type trubines characterized by lower head loss and a wider normal operating flow range than class Ⅰ models.
