Toppling gravestones are not only annoying for those who are entitled to use the gravesite, but can also cause life-threatening injuries. For this reason, all cemeteries in Germany are required to undergo stability tests on standing tombs after the frost period. Correct implementation must be verifiably documented in a test log. In order to do this in accordance with the regulations and verifiably, each standing gravestone must be subjected to the minimum force of 300 Newtons once a year. If a grave stele withstands this force on its upper edge in all directions, its stability is in accordance with the TA gravestone given. If not, the first immediate measure is to mark the gravestone with at least a warning and ask the gravesite owner to restore stability. Our warning sticker meets these requirements and thus the cemetery operator fulfills his duty of care: he is immune from claims for damages and claims for pain and suffering as a result of a toppled gravestone.
