There is usually no acoustic classification for tapware used in supply systems of Type 2 and no specifications governing the level of noise emissions from these water installations. If supply pressures are such that excessive noise is generated it is recommended that pressure or flow regulators are fitted in the system. Or where practicable, tapware conforming to the appropriate acoustic classification are used.
Annex B lists possible consequences of using a product outside its recommended operating range. SIST EN 15091:2014

a It is permitted to serrate or knurl this thread to assist the retention of sealing tape or compounds. In such cases, the lower deviation tolerance on the basic major diameter indicated in EN ISO 228-1 may be increased to – 0,35 mm. Use of deformable washers is permissible. NOTE Other dimensions are permissible (for replacement) when market tradition requires it, provided the manufacturer specifies the actual dimensions in literature to avoid confusion with the standard dimension – which can be achieved using an excentric connection.
5.2.9 Nozzle outlets for use with flow rate regulators Nozzle outlets to accept flow rate regulators shall be in accordance with EN 246. Nozzle outlets not in accordance with EN 246 are covered by 5.2.10. 5.2.10 Special cases Tapware intended for special applications e.g. for installation on sanitary appliances not conforming with European Standards or where dimensional interchangeability is not a requirement may incorporate dimensional deviations, provided: — all other requirements of this standard are satisfied; — secure fixing to the mounting surface is provided with all fixing holes covered; — thread connection to the supply pipes complies with EN ISO 228-1; — suitable air gap dimension or a backflow prevention device is provided. The manufacturer's literature including the installation instructions supplied with the tapware shall indicate clearly that the tapware has unique characteristics e.g. not standard dimensions. 5.3 Hydraulic characteristics 5.3.1 General The tests described are type tests (laboratory tests), not quality control tests carried out during manufacture. This clause gives a test method for measuring the flow rate and the cross-flow between the hot and cold water supply for a given pressure. SIST EN 15091:2014
