Standards :
GB/T 9138-2015 Concrete Test Hammer, the National Standard of the People's Republic of China
National Metrological Verification Regulation of the People's Republic of China "Concrete Test Hammer" JJG 817-2011
The National Standard of the People's Republic of China "Technical Standard for the Field Detection of Masonry Works" GB/T 50315-2011
Product characteristics:
Brick rebound hammer is the equipment that one spring drives the impact hammer and impacts the resilience of transient elastic deformation produced on the surface of sintered common brick masonry or sintered porous brick masonry middle brick, so that the hammer drives the pointer to rebound and points the rebound distance. The rebound value is used as one of indexes of compressive strength of sintered common brick masonry or sintered porous brick masonry middle brick to deduce the compressive strength label of the brick.
Because of the advantages in light weight, flexibility, low price, easiness to operate, non-damage, wide detection surface, convenient and rapid test, the concrete test hammer is widely used in practical engineering detection.
