1.3 EU Pressure Equipment Directive
These devices are designed, assembled and tested to agree with the EU Pressure Equipment
Directive (PED). The CE mark on the nameplate shows that the manufacturer did a conformity
assessment. The PED conformity assessment is approved by a Notified Body. The identification
number of the Notified Body is given on the nameplate.
A code on the nameplate gives data about the PED rating of the device:
For more data about the nameplate refer to
Bypass chamber nameplate
on page 13 ("Namur").
The manufacturer did a risk analysis on the device that agrees with the Pressure Equipment
Directive. All personnel must know the design and operating conditions that follow to prevent the
risk of damage and injury:
•
This device is designed to function at almost constant pressure and temperature conditions.
A maximum of 500 cycles is permitted along the full pressure range. A maximum of 2000
cycles is permitted along the full temperature range.
•
This device is not designed for operating conditions where vibration or fatigue stress is
present.
•
Events that are not taken into account in the calculations include exceptional risks such as:
earthquakes, bad weather, fire etc..
•
The standard design calculation does not take into account the theoretical coefficient of
corrosion. The product circulating in the device must not have properties that cause surface
erosion.
•
Our conformity declaration is limited to the parts of the device that are pressurized. It does
not include parts that can be dismantled (valves etc.).
•
The process connections must be attached correctly to prevent mechanical stress. The axis
of the process connection must be parallel to and centred with the axis of the tank's process
connections. Tighten the process connections in agreement with the design code.
•
The user must take necessary steps to protect the installed device from shock waves (water
hammer). A pressure-limiting valve must protect the installation.

WARNING!
The process pressure (PS) and process temperature (TS) are given on the device nameplate and
are only applicable to your bypass chamber. Do not use the device at a process pressure more
than the maximum limit for a given process temperature. For more data, refer to Maximum
process pressure: bypass chamber on page 37
.
WARNING!
If the device has an Ex approval, then you must obey other temperature limits. For more data,
refer to the Ex supplementary instructions.
