Evaluation: None of the tested substances could be detected in measurable concentrations
with the exception of formaldehyde and acetaldehyde. The measured values are below the
specific limit of detection set for each analysis so the tested products are assigned to emission
class A+ (

2.5 Heavy metals
By determining the metals contained in the building materials, a statement can be made re-
garding health risks and possible environmental hazards of the base products used. The most no-
torious environmentally harmful heavy metals are lead, cadmium and mercury.
Test method: Quantitative determination according to DIN EN ISO 17294-2 using ICP-MS (induc-
tively coupled plasma mass spectrometry). This method enables detection of a large number of
elements in a short time and, due to its capability to detect elements reliably, it is one of the
most common methods of trace element analytics.
The limit values according to LAGA (working group of the German federal states on waste is-
sues) are used to identify a possible environmental impact due to heavy metals. The assignment
values Z 0 to Z 2 are the upper limits for each incorporation class when ground material is used
for earthworks, road building, landscaping and landfill work (e.g. cap layers), for the filling of
building pits and for land reclamation.
Z 0: Unrestricted incorporation
Z 1.1: Restricted incorporation in open sites
