Übersetzung für "Test cabinet" in Deutsch

Procedure Tests shall be carried out in the test cabinet in subdued light.

A commercial climate test cabinet was used for temperatures down to -40°C.

Temperature and Climate Test Cabinet Weiss SB222/500 used (print version)

These tests were performed in a climatic test cabinet from Weiss, year of construction 1989, under the following conditions:

The exsiccator is temperature-controlled in a climatic test cabinet for 48 h at constant 50° C.

The system can be coupled with a height-adjustable 2200-litre climatic exposure test cabinet in both types of operation.

The degree of hydration was determined in samples which had been kept in a climatic test cabinet for 48 hours at a temperature of 40° C. and an atmosphere of 95 percent relative humidity.

The prepared tresses were then dried and conditioned overnight in the climatic test cabinet at 25° C. and 50% relative humidity or at 25° C. and 75% relative humidity.

The complete measurement is carried out in the climatic test cabinet under constant climatic conditions at 25° C. and 50% relative humidity or at 25° C. and 75% relative humidity.

The shelf life was investigated by subsequently storing the cores for an additional 24 hours in a climatic test cabinet (from Rubarth Apparate GmbH) at 30° C. and a relative atmospheric humidity of 60%, which corresponds to an absolute atmospheric humidity of 18.2 g/m 3, and their bending strength was measured again.

The accuracy with which the specified values for temperature and atmospheric humidity were prepared by the climatic test cabinet was checked regularly with a calibrated testo 635 humidity/temperature/pressure dew point measuring device from the testo company.

Comparison of Examples 1.2 to 1.6 clearly shows that with increasing [Li 2 O active]/[M 2 O] amount of substance ratio the shelf life of the binder increases, such that a residual strength of 94%, based on the cold strength, after storage in the climatic test cabinet can be achieved.

Whereas for Examples 1.11 to 1.13 the strengths of the cores after storage in the climatic test cabinet increase with increasing molar ratio, because of the opposite trend of the decreasing cold strengths no absolute improvement can be achieved.

The printed samples were then stored for 7 days in a climatic test cabinet of Heräus at a temperature of 40° C. and relative humidity of 80%.

The samples were stored in glass containers equipped with airtight screw caps in a climatic exposure test cabinet for various periods at 23° C. or 40° C.

Whereas, for example, the German Association of the Automotive Industry (VDA) test requires the pollutant concentrations to be measured in a test cabinet, in Asia the samples are usually packaged in bags and then heated in an oven.

Surprisingly the compounds used in accordance with the invention, containing one or more above-defined organic anions, exhibit no particular increase in H 2 O content (Karl-Fischer method) following 48 h storage at 90% relative air humidity at 35° C. in a conditioning test cabinet, while the analogous double hydroxides with inorganic anions have much higher H 2 O contents, in some cases a multiple of that prior to conditioning storage.
