PRESSURE EQUIPMENT DIRECTIVE CALCULATOR

Determine the correct conformity assessment module and procedures in just a few clicks

Do you find it difficult or time consuming to determine the correct PED conformity assessment module or follow the correct module procedures?

Many of our clients do, which is why we have put together an interactive PED calculator.

It calculates the correct conformity assessment module and provides the procedures to follow in under 60 seconds with just four easy steps.

To start the calculator, select your pressure equipment type.

PED Guideline B-41

Where to find additional information on classification of fluids based on PED Article 13 as of 1 June 2015?

As of 1 June 2015 classification of fluids is based on article 13 of PED 2014/68/EU. Article 13 paragraph 1 (a) lists the physical and health hazard classes and categories for substances and mixtures included in Group 1. The classification is based on the CLP Regulation (EC) No 1272/2008. The table below provides an overview of the hazard classes and categories and the corresponding hazard statements according the CLP Regulation including references to the criteria and label elements in the CLP Regulation.

Note 1

Article 13 paragraph 1 (a) also states that "Group 1 comprises also substances and mixtures contained in pressure equipment with a maximum allowable temperature which exceeds the flash point of the fluid". The purpose of this provision is to ensure that the flammability hazard is properly addressed for those substances and mixtures which are not classified as flammable under the CLP Regulation (based on the temperature criteria of the CLP Regulation) but which are presenting this hazard due to the maximum allowable temperature (TS).

For example, Heat transfer oils are not classified as flammable liquids according to the CLP Regulation because their flashpoint is above 60 °C (see CLP Regulation Annex I, Table 2.6.1 in Section 2.6 Flammable Liquids, 2.6.2 Classification criteria). However, if the maximum allowable temperature (TS) is above the flashpoint, the hazard of heat transfer oil corresponds to a Group 1 fluid.

Note 2

Please note that the CLP Regulation is subject to adaptations to technical progress and therefore the information in the table above should be checked with the version of the CLP Regulation in force at the time the equipment is placed on the market.

Note 3

For questions related to the CLP Regulation please consult your national CLP-helpdesks. Further information on the CLP Regulation can be found on the European Chemicals Agency (ECHA) website: www.echa.europa.eu. On the ECHA website there is also a list with the contact details of all national CLP-helpdesks.

Calculating Pressure Vessel Volume

To calculate the volume of a pressure vessel, choose applicable vessel sections and input data for each section in turn. The calculated volume for each section will be added to the total volume. The volume of features which have not been calculated can be input as "Additional Volume"
