CE marking for simple pressure vessels done! With easyCE expert support.

• Welded vessels for air or nitrogen, not intended to be fired, with internal gauge pressure above 0.5 bar.
• Pressure-resisting parts made from non-alloy quality steel, non-alloy aluminium or non-age-hardening aluminium alloys.
• A circular cylindrical section closed by outwardly dished and/or flat ends on the same axis, or two dished ends on the same axis.
• Maximum working pressure of 30 bar and PS × V no greater than 10,000 bar.L.
• Minimum working temperature of at least −50°C; maximum working temperature no higher than 300°C for steel or 100°C for aluminium or aluminium alloys.

• Vessels specifically designed for nuclear use where failure could release radioactivity.
• Vessels specifically intended for installation in, or propulsion of, ships and aircraft.
• Fire extinguishers.

A vessel outside this directive may still fall under other legislation, such as the Pressure Equipment Directive.

• Designing and manufacturing the vessel to meet the essential safety requirements.
• Preparing technical documentation and completing the prescribed conformity assessment.
• Issuing the EU declaration of conformity and affixing CE marking after conformity is demonstrated.
• Keeping the documentation and declaration for ten years after placing the vessel on the market.
• Maintaining conformity in series production and reviewing relevant changes.
• Providing type and serial or batch identification, manufacturer contact information, instructions and safety information in the required language.

Vessels with PS × V of 50 bar.L or less must follow sound engineering practice and bear the specified inscriptions, but not CE marking under this directive.

• Above 3,000 bar.L: Module C1, with supervised vessel testing.
• Above 200 and up to 3,000 bar.L: Module C1 or C2, the latter involving supervised vessel checks at random intervals.
• Above 50 and up to 200 bar.L: Module C1 or Module C, based on internal production control.

The manufacturer and notified body should establish the precise route and evidence before production.

• Supply in a normalised condition or an equivalent state.
• Carbon content below 0.25%, with sulphur and phosphorus each below 0.05%.
• Maximum tensile strength below 580 N/mm².
• The specified impact-energy requirements at the minimum working temperature. Annex I sets a mean KCV of at least 35 J/cm² for three longitudinal test pieces, together with individual-value and additional testing conditions.

• Non-alloy aluminium must contain at least 99.5% aluminium.
• Materials must be supplied in the annealed condition and have adequate resistance to intercrystalline corrosion.
• Maximum tensile strength must not exceed 350 N/mm².
• Elongation after fracture must be at least 16% for a test piece parallel to the rolling direction and at least 14% for one perpendicular to it.

• Access for inspecting the inside of the vessel and provisions for draining it.
• Maintaining the necessary mechanical properties throughout the intended service life.
• Suitable protection against corrosion for the intended use.
• Avoiding loads that impair safety in use.
• Preventing internal pressure from remaining above the maximum working pressure; a momentary excess of up to 10% is permitted by the directive.

• A description of the vessel, its intended use and relevant risk assessment.
• Design and manufacturing drawings and component details.
• Explanations of drawings, calculations and vessel operation.
• The harmonised standards or other technical specifications used and any alternative technical solutions.
• Design calculations and examination or test results.
• Instructions and safety information.
• Material specifications, welding procedures and the supporting qualification and inspection records required by the selected assessment route.

• Identify the applicable legislation and scope.
• Determine the vessel category and essential requirements.
• Select the conformity assessment modules.
• Assess the design and manufacture, including the required examinations and tests.
• Compile the technical documentation and instructions.
• Issue the declaration and affix the CE marking after conformity has been demonstrated.

• The identification number of the notified body involved in the production-control phase follows the CE marking.
• The vessel must also carry the inscriptions required by Annex III, such as pressure, temperature and identification information.
• Additional markings must not obscure or undermine the required markings.
• CE marking must not be applied under this directive to vessels with PS × V of 50 bar.L or less.
