Article 14 User inspectorates
1. By way of derogation from the provisions relating to the tasks carried out by the notified bodies, Member States may authorize in their territory the placing on the market, and the putting into service by users, of pressure equipment or assemblies referred to in Article 1 of which conformity with the essential requirements has been assessed by a user inspectorate designated in accordance with the criteria referred to in paragraph 8. 2. When a Member State has designated a user inspectorate in accordance with the criteria set out in this Article, it may 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 provided for in this Article of pressure equipment or assemblies the conformity of which has been assessed by a user inspectorate designated by another Member State in accordance with the criteria set out in this Article. 3. Pressure equipment and assemblies the conformity of which has been assessed by a user inspectorate shall not bear the CE marking. 4. The pressure equipment and assemblies referred to may be used only in establishments operated by the group of which the inspectorate is part. The group shall apply a common safety policy as regards the technical specifications for the design, manufacture, inspection, maintenance and use of pressure equipment and assemblies. 5.

Article 15 CE marking
1. The CE marking consists of the initials ‘CE’ in accordance with the model in Annex VI. The CE marking shall be accompanied by the identification number, as referred to in Article 12 (1), of the notified body involved at the production control phase. 2. The CE marking shall be affixed in a visible, easily legible and indelible fashion to each — item of pressure equipment referred to in Article 3 (1), or — assembly referred to in Article 3 (2) which is complete or is in a state permitting final assessment as described in section 3.2 of Annex I. 3. It is not necessary for the CE marking to be affixed to each individual item of pressure equipment making up an assembly as referred to in Article 3 (2). Individual items of pressure equipment already bearing the CE marking when incorporated into the assembly shall continue to bear that marking. 4. Where the pressure equipment or assembly is subject to other Directives covering other aspects which provide for the affixing of the CE marking, the latter shall indicate that the pressure equipment or assembly in question is also presumed to conform to the provisions of those other Directives. However, should one or more of those Directives allow the manufacturer, during a transitional period, to choose which arrangements to apply, the CE marking shall indicate conformity only with the Directives applied by the manufacturer. In this case, the particulars of the said Directives, as published in the Official Journal of the European Communities , must be given in the documents, notices or instructions required by the Directives and accompanying the pressure equipment or assembly. 5. The affixing of markings on pressure equipment or assemblies which are likely to mislead third parties as to the meaning or form of the CE marking shall be prohibited. Any other marking may be affixed to pressure equipment or assemblies provided that the visibility and legibility of the CE marking is not thereby reduced.
Article 16 Unduly affixed CE marking
Without prejudice to Article 8: (a) where a Member State establishes that the CE marking has been affixed unduly, the manufacturer, or his authorized representative established within the Community, shall be obliged to make the product conform as regards the provisions concerning the CE marking and to end the infringement under the conditions imposed by the Member State; (b) should non-conformity persist, the Member State must take all appropriate measures to restrict or prohibit the placing on the market of the product in question or to ensure that it is withdrawn from the market in accordance with the procedures laid down in Article 8.

Member States shall take appropriate measures in order to encourage the authorities responsible for implementing this Directive to cooperate with each other and provide each other and the Commission with information in order to assist the functioning of this Directive.
Article 18 Decisions entailing refusal or restriction
