Assessment Procedures.
The valves with DN equal or lower than DN25 are not included in compliance with Article 4, paragraph 3.
Valves designed for use with gas, liquid gas, gases dissolved under pressure, steam and those liquids with a vapour
pressure at maximum admissible temperature exceeding 0.5 bar at normal atmospheric pressure (1.013 mbar) are
included within the following limits:
- The valves with DN ranging from 32 to 100 (included) with Group 1 fluids;
- The valves with DN equal or higher than DN125 with Group 2 fluids.
The end user must carry out noise assessment testing once the
