Drop Hammer Test
Traditional screeds are tested for soundness with BRE drop hammer test
The device consists of a 1m long cylindrical guide rod a long which an annular weight of 5kg (2.5kg if screed on insulation) travels when released. At bottom of the guide rod the weight strikes the collar of a case hardened steel anvil which transmits the impact to the selected area of screed. Four successive impact blows on the same spot are sufficient to create an indent in the screed. The depth of the indent determines the strength of the screed.
