'The Pressure Equipment Directive (PED, 97/23/EC) adopted by the European Parliament and the European Council in May 1997. It has initially come into force on 29 November 1999. From that date until 28 May 2002 manufacturers have a choice between applying the pressure equipment directive or continuing with the application of the existing national legislation. From 29 May 2002 the pressure equipment directive will be obligatory throughout the European Union.' (text from the original PED site)
Also the related EN codes are getting more momentum. Tools to calculate according the EN code are available (also at Red-Bag), EN materials can be purchased and manufacturers are getting more acqainted with the European code requirements.
This page provides a starting point when dealing with equipment or piping according the Pressure Equipment Directive. The first step is usually to determine the classification category of the equipment or piping. This classification defines the further requirements such as material certificates, design method and calculations, testing and documentation requirements.
PED classification procedure in short
- Provide a tag (or equipment) number and optionally a name to identify the subject item
- Indicate the type of equipment which will define one of the three table groups (1,2,3,4 or 5 or 6,7,8,9)
- Only for the pressure accessory it is required to indicate the assessment background (volume or nominal size of pipe)
- Select the fluid state and group, this will define the applicable table
- Enter the maximum pressure, maximum temperature (is sometimes required for example generators), the volume (for equipment and accessories) or the nominal diameter DN (for piping and accessories)
- The additional information is required to be selected where applicable to determine possible exceptions to the classification tables
Enter the above information in the following page and the classification category will be calculated: PED classification >.
