Performance ZRS engineers:

The testing institutes active in Germany in the testing of earth building materials meet regularly to exchange experiences. ZRS engineers are members of this so-called PÜZ-committee for earthen building products and together with BAM they are active in a leading position. Frequently, so-called interlaboratory tests are carried out, in which the validity of the standardised test methods is checked or recommendations for their modification are made to the DIN standards committee for earth construction.

The picture shows the testing of the criterion of abrasion of clay plaster surfaces according to DIN 18947:2018-12, which has been mandatory since 2018.
