ATEX certification for the ETH cylinder is always for specific ATEX application data.
Therefore, we need your precise application data in advance.

Maximum ambient temperature
In general it must be taken into consideration, that the
maximum ambient temperature of the ETH cylinder is
the temperature which can act upon any spot of the
cylinder surface when the thrust rod is extended.
In addition, it applies for the measurement:
Linear interpolation of F(x) or F(t) between
interpolation points.
For x(t), no interpolation between interpolation points.

Measurement of the internal heat generation
We set up your cycle in the lab and measure the maximum
temperature occurring at the screw nut. This is the spot
where the cylinder is most susceptible to heating up.

Evaluation of the measurement results / measures
Application can be released
If the permitted internal heat generation is met, the
application specific ETH ATEX certification can be
granted (proceed from 5.)
Application can not be released
If the internal heat generation is too high, modifications
are required.
The required modifications are defined in cooperation
with Parker. (proceed from 2.)

ATEX release
ATEX Certification for the submitted ATEX application data
and the specific ETH cylinder defined by the order code.
Allocation of an unambiguous A number (part of the
order code) for the ATEX application data verified.
Via the A number included in the order code and the
designation for ATEX cylinders (17th digit in the order
code = “A”), the ETH ATEX cylinder is unambiguously
defined and can be ordered accordingly.
