DIRECTIVE 97/23/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 29 May 1997 on the approximation of the laws of the Member States concerning pressure equipment  

 
1.2. Fired or otherwise heated pressure equipment with the risk of overheating intended for generation of steam or super-heated water at temperatures higher than 100°C having a volume greater than 2L, and all pressure cookers (Annex II, table 5). 
 
1.3. Piping intended for: 
(a) gases, liquified gases, gases dissolved under pressure, vapours and those liquids whose vapour pressure at the maximum allowable temperature is greater than 0,5 bar above normal atmospheric pressure (1 013 mbar) within the following limits: 
- for fluids in Group 1 with a DN greater than 25 (Annex II, table 6), 
- for fluids in Group 2 with a DN greater than 32 and a product of PS and DN greater than 1 000 bar (Annex II, table 7); 
(b) liquids having a vapour pressure at the maximum allowable temperature of not more than 0,5 bar above normal atmospheric pressure (1 013 mbar), within the following limits: 
- for fluids in Group 1 with a DN greater than 25 and a product of PS and DN greater than 2 000 bar (Annex II, table 8), 
- for fluids in Group 2 with a PS greater than 10 bar, a DN greater than 200 and a product of PS and DN greater than 5 000 bar (Annex II, table 9). 
 
1.4. Safety and pressure accessories intended for equipment covered by 1.1, 1.2 and 1.3 including where such equipment is incorporated into an assembly. 
 
2. The assemblies defined in Article 1, section 2.1.5, which include at least one item of pressure equipment covered by section 1 of this Article and which are listed in 2.1, 2.2 and 2.3 of this Article must satisfy the essential requirements set out in Annex I. 
 
2.1. Assemblies intended for generating steam or superheated water at a temperature higher than 100°C comprising at least one item of fired or otherwise heated pressure equipment presenting a risk of overheating. 
 
2.2. Assemblies other than those referred to in 2.1, if the manufacturer intends them to be placed on the market and put into service as assemblies.

 

2.3. By way of derogation from the introductory paragraph to this section, assemblies intended for generating warm water at temperatures not greater than 110 °C which are manually fed with solid fuels and have a PS 7V greater than 50 bar 7L must comply with the essential requirements referred to in 2.10, 2.11, 3.4, 5 (a) and 5 (d) of Annex I. 
 
3. Pressure equipment and/or assemblies below or equal to the limits in sections 1.1, 1.2 and 1.3 and section 2 respectively must be designed and manufactured in accordance with the sound engineering practice of a Member State in order to ensure safe use. Pressure equipment and/or assemblies must be accompanied by adequate instructions for use and must bear markings to permit identification of the manufacturer or of his authorized representative established within the Community. Such equipment and/or assemblies must not bear the CE marking referred to in Article 15. 
 
 

1.1.

Article 4  Free movement

Member States shall not, on grounds of the hazards due to pressure, prohibit, restrict or impede the placing on the market or putting into service under the conditions specified by the manufacturer of pressure equipment or assemblies referred to in Article 1 which comply with this Directive and bear the CE marking indicating that they have undergone conformity assessment in accordance with Article 10
 

1.2. Member States shall not, on grounds of the hazards due to pressure, prohibit, restrict or impede the placing on the market or putting into service of pressure equipment or assemblies which comply with Article 3 (3). 
 
2. Member States may require, to the extent that it is needed for safe and correct use of pressure equipment and assemblies, the information referred to in Annex I sections 3.3 and 3.4 to be provided in the official language(s) of the Community which may be determined in accordance with the Treaty by the Member State in which the equipment or assembly reaches the final user.
