Flatness test of a building facade

For the examination of the flatness tolerances according to DIN 18202, a laser scanner Surphaser is very well suited due to its sub millimeter measurement accuracy. The Surphaser model 400 has a measuring noise of 0.2mm (0.9mm) up to 30m (160m) distance.

The picture shows the color-coded flatness of a subsequently heat-insulated external facade wall (width = 8m).

DIN 18202 is a German standard that describes the tolerances for buildings and civil engineering works. It provides specifications for tolerances in linear dimensions and angular deviations in construction projects. The standard covers various aspects of construction, including foundations, walls, floors, ceilings, roofs, and other structural elements.

The tolerances defined in DIN 18202 are crucial for ensuring the quality and accuracy of construction projects. They help to establish acceptable limits for deviations from the specified dimensions and angles, ensuring that the finished structure meets the required standards and functions properly.

DIN 18202 provides guidance for architects, engineers, contractors, and other professionals involved in construction projects, helping them to understand and implement the necessary tolerances to achieve the desired quality and performance of buildings and civil engineering works.
