Pressure equipment directive
For instruments with nominal widths of ≤ DN 25 (1"), an EU conformity assessment in
■
accordance with the pressure equipment directive (PED) is not permitted.
Instruments with nominal widths of ≤ DN 25 (1"), and thus without CE marking, should
■
be designed and manufactured in line with the applicable sound engineering practice
(PED article 4, chapter 3).
For instruments > DN 25 (1") and for the associated marking on the measuring
■
instrument or thermowell, WIKA confirms conformity with the pressure equipment
directive in accordance with the conformity assessment procedure, module H.
For further specifications see WIKA data sheet TE 60.25 and the order documentation.
