Test of pressure equipment
According to the Pressure Equipment Directive (PED 97/23/EC) and TÜV Darmstadt (German
supervising authorities). State: 10th of December, 2005
Subject pressure equipment with a product permissible operating pressure [bar] x content volume
[litres] from 200 up to max. 1000.
Example: Filter housing 0.5 l
Maximum operating pressure: 350 bar
Content volume: 0.5 litres
350 bar x 0.5 litres = 175
175 is smaller than the minimum of 200 -> result: Test is not applicable!!
Pressure equipment from 200 up to 1000 have to be tested as follows:
1. Examination after 5 years by a qualified person or authorized organisations.
Visual inspection, inside and outside.
2. Examination after 10 years by a qualified person or authorized organisations.
Visual inspection, inside and outside.
In addition, a water pressure test is carried out at 1.5 times of the permissible vessel operating
pressure.
