RTA has protective clothing available but it is advisable to bring your own scarf, gloves, beanie/cap and jacket. Grippy, warm shoes are not available and must be brought by oneself.  


Climatic Simulation

All climatic simulations are carried out as instructed by the customer. RTA accepts no liability for any resulting damage caused to the test object.

The Vienna Climatic Wind Tunnel is a complex facility which is carefully maintained and continuously further developed by RTA in order to ensure that the facility remains state of the art. Despite all these efforts, however, technical malfunctions may arise which delay or restrict testing operations. Sometimes, especially at weekends, repairs may only be possible in exceptional cases. RTA makes every effort to keep downtimes to a minimum.

Any resulting delays in the testing schedule will be discussed with the customer in order to find an optimum solution to compensate for the delay (e.g. rescheduling tests, using time reserves, splitting tests according to priorities, offering alternative periods for testing).

The customer shall be responsible for ensuring that only suitable test objects are submitted for testing in the Climatic Wind Tunnel.

Transport, Packaging

The customer shall be responsible for organising the transport (incl. timely transport or landing permits, accompanying documents, special transport arrangements) at his own expense and for appropriate packaging of the test objects. Deliveries of any necessary equipment, spare parts etc. must be coordinated with RTA prior to the arrival of the test objects.

All materials (spare parts, packaging material etc.) for the return transport shall be properly and immediately prepared by the customer, failing which RTA will charge the costs for transport and external storage. If the customer requires RTA’s assistance in preparing the return transport of the test object, this must be coordinated and requested in advance. RTA can provide support in loading operations on Monday to Friday1 between 7:00 and 15:30; this support must be coordinated and requested in advance. The customer shall be responsible for ensuring that the goods are suitable for transport.


Customs Clearance

Customs declaration and clearance, any charges and import duties related thereto shall be the responsibility of the customer and shall be organised and paid by the customer. RTA will be glad to support the customer, if required, (see “assistance customs affairs - third party countries”), but will not accept liability for any misdeclarations.

The following information may help you to organise transport and customs affairs: pdfAssistance with customs affairs


Measurement setup and Preparation

The measurement equipment will not be installed until the customer has confirmed the test schedule and sensor plan. These plans and schedules will be prepared by the responsible RTA project manager after contract placement and forwarded to you for coordination and approval.

The customer shall provide on-site support during measurement setup (Monday through Friday1 7:00 to 15:30), in particular where special measurement points are required. The customer may be required to assist in moving the test object into the climatic test facility, if necessary.

Unless agreed otherwise, the test object will no longer be available to the customer once RTA staff have started installing the measurement equipment. 

We ask you to inform us of any preparation work you plan to carry out after the delivery of the test object so that we have time to coordinate procedures prior to the arrival of the test object. The preparation halls can be rented for this purpose on a daily basis.


Start-up, Electrical installations and Adjustments 

The customer shall be responsible for start-up of the test object following arrival at RTA (energising, powering up…) and shall support the process on site. RTA provides the power supply for the test object and is available for assistance.

Electrical installations for power and energy measurements which require opening the power supply of the test object must be carried out and approved by an authorised specialist provided by the customer during measurement setup from Monday through Friday1 between 7:00 and 15:30.

If necessary the customer may make additional adjustments to the test object in the preparation hall (e.g. fresh air rate settings, modifications etc.) in consultation with RTA even between 15:30 and 22:00. The customer will not incur additional charges if RTA staff is on site during that time because of parallel projects.

Once the tests in the climatic wind tunnel are completed, any cabling installed by the customer (e.g. computer interface cables) must be removed in consultation with RTA at the earliest possible time so that the test object can be removed by 11:00 at the latest.


Test procedure

RTA operates its facilities 6 testing days per week (Monday through Saturday). 

The customer should be continuously present during the tests in the climatic wind tunnels, at least until 17:00 (we recommend staying for the late shift until 23:00) in order to be able to make quick decisions based on current measurement results and to determine the testing programme for the late and night shifts. We also recommend scheduling a daily meeting before 16:00 to discuss the current test results and adapt the programme, if required.

We kindly ask you to give us feedback. We have prepared a feedback questionnaire and would like to discuss the findings with you. Please help us to improve our test service.


Online live observation of tests via remote control

RTA provides the possibility to monitor and observe the performance of climatic tests from any given place provided an internet connection is available. By this measure business travel as well as related costs and envirnomental impact can be reduced because the number of present technicians may be optimised to a minimum.  

If you want to use the remote connection for your project please contact your project manager in charge.


Presence of customer during measurement setup and climatic tests 

The customer shall nominate a professionally qualified representative familiar with the project prior to transport (incl. customs clearance), who will support testing on site and is authorised to make decisions concerning the test procedure and any supplementary tests. The customer representative shall ensure that all arrangements have been made for the return transport of the test object.

If the customer wishes to expand the scope of services, RTA requires a written follow-up order by the authorised customer representative.
