PED Pressure Equipment Certification

PED Directive 2014/68/EC

PED stands for Pressure Equipment Directive, which means Pressure Equipment Directive.

The new directive 2014/68/EC was enforced in July 2016.

The PED directive stipulates that the design, manufacturing, and conformity assessment of all pressure equipment with a maximum allowable pressure greater than 0.5 bar that must enter the EU market must meet the requirements of this directive.

1. What products are included in the CE certification of PED

The PED stipulates that all pressure equipment with a maximum allowable pressure greater than 0.5 bar must comply with the requirements of the PED, which is much broader than the regulations in China and includes the following categories

1. Pressure vessel

2 Pressure pipelines

3 Safety attachments

4 Pressure attachments

5 components

here:

Composite component refers to a manufacturer assembling several pressure equipment into a single functional unit.

2. What products are not included in the CE certification of PED

1) A pipeline designed to transport fluids or substances from or to a station (onshore or offshore), as well as a pipeline composed of pipelines, including all additional equipment specifically designed for official lines, starting from the final isolation device;

20) Radiators and pipelines for hot water heating systems;

21) Designed to hold liquids with an air pressure not exceeding 0.5 bar.

3. Classification of PED products and CE certification mode

The EU's classification of pressure equipment is mainly based on the following parameters:

Filling medium; Volume V (L); Allowable pressure PS (bar); Diameter DN (mm)

The conformity review modes for different categories of pressure equipment are shown in the table below



The selection of compliance review mode depends not only on the hazard classification of the equipment, but also on the production type (single piece production or batch production) and quality management (routine inspection or quality assurance system) of the equipment, as shown in the table below



The description of each mode is as follows:
