The Scope
PI Marking of Transportable Pressure Equipment (TPED) verifies that transportable pressure equipment complies with applicable European safety, design, manufacturing, inspection, and conformity assessment requirements before being placed on the market. The certification ensures that pressure receptacles used for the transport of compressed, liquefied, or dissolved gases meet the required standards for safety, reliability, and performance throughout their operational lifecycle.
The PI Mark demonstrates that the equipment has successfully undergone the required conformity assessment procedures and is authorised for use and circulation within applicable markets.

Directive 2010/35/EU – Transportable Pressure Equipment Directive (TPED)
Directive 99/36/EC – Transportable Pressure Equipment Directive
Directive 97/23/EC – Pressure Equipment Directive (PED)
Applicable European standards governing transportable pressure equipment
Relevant conformity assessment, inspection, and approval requirements
The certification may include:
Conformity assessment of transportable pressure equipment
Approval of materials and manufacturing processes
Quality assurance system assessment
Verification of design and manufacturing compliance
Qualification of welding procedures and welders
Qualification and approval of Non-Destructive Testing (NDT) personnel
Inspection and certification of pressure receptacles and assemblies
Who Should Apply
PI Marking certification is suitable for manufacturers, owners, operators, inspection bodies, and organisations involved in the design, manufacture, maintenance, testing, or distribution of transportable pressure equipment.
