Design and CE-Approval

Table of Contents

Berghof high-pressure laboratory reactors are designed, built, and tested following the Pressure Equipment Directive DGR 2014/68/EU and the AD-2000 regulations.This includes in particular:

  • EU type examination/design type (module B) according to DGR 2014/68/EU
  • Conformity to type (module F) according to DGR 2014/68/EU

Regardless of material and size, all reactors are designed with a corrosion allowance of at least 1 mm. Every BERGHOF high-pressure laboratory reactor is subjected to a pressure test to prove the pressure resistance of the finished product. The level of the test pressure corresponds to AD-2000 Merkblatt HP30, Section 4.17 This ensures the function of each reactor and delivery is made with the corresponding works certificate.

CE marking:

Pressure equipment as defined by EU Directive 2014/68/EU is categorized according to the fluids used in it and the pressure content product. The fluids are divided into 2 groups.

  • Group 1: hazardous fluids (explosive substances/mixtures, flammable gases, oxidizing gases, flammable liquids, pyrophoric liquids, oxidizing liquids, acutely toxic substances);
  • Group 2: all substances that do not belong to fluid group 1.


Since the high-pressure laboratory reactors manufactured and sold by Berghof are intended for use in chemical laboratories, they generally fall into group 1 - hazardous fluids! The diagram below thus shows the categorization according to the pressure content product, which ultimately defines the test intervals to be observed.

The pressure content product is the product of the max. operating pressure (in bar) and the volume (in liters) and is thus a measure of the energy stored in the pressure device.

Pressure content product: P x V = [bar x l].

As can be seen from the diagram shown, Berghof laboratory reactors with a volume of less than 1000 ml and a max. working pressure of 200 bar cannot be assigned to any category. These are to be designed, constructed, and tested according to Art. 4 para. 3 (PED 2014/68/EU). These vessels are not subject to CE marking and must not be CE marked.
