Air-conditioned test hall
Hygrothermics
| Measurement | Total water content, driving rain load |
| Standard | Own testing method |
| Measurement object | Wall elements in air-conditioned test hall exposed at the exterior to natural climate conditions |
Technical data
| Sample size | Wooden frame 50 × 50 cm, width: 20 cm or 40 cm |
| Field investigation | Wall with different composition Outdoor climate exposure to the west or east |
Special features
| Accredited by DAkkS D-PL-11140-11-02 |
The laboratory has a flexible accreditation according to DIN EN ISO/IEC 17025 Test laboratory moisture, mortar, radiation, emmissions |
| Test reports can be issued | |
| The wall elements can be removed from the test hall façade with a fork lift and weighed. Changes in weight of the wall elements can be determined, which are in correlation with the total water content. |
More information
Determination of moisture absorption or release to small-format wall elements, which are exposed to a controled interior climate in the winter and to natural weathering on the outside. This method is meant to compare for example different external coatings or insulation systems. Moisture content, temperature profiles and heat fluxes can be measured.
