2)Quantity required
One(1) unit- standard BS EN
3)Technical specifications
a.Vertical post and cross bar
-To hold cylinder/impactor
b.Pneumatic cylinder
-To hold, release and raise the impactor
-Height: Adjustable height up to 300mm (adjustable)
c.Impactor consists of (refer attachment):
-Circular body –200 mm in diameter, separated from the striking surface by helical compression springs
and free to move relative to it on a line perpendicular to the plane of the central area of the striking
surface. The body and associated parts minus the springs shall have a mass of (17±0.1) kg and the whole
apparatus including mass, springs and striking surface shall have a mass of (25±0.1) kg.
-Spring – the nominal spring rate of the combined spring system is (7±2) N/mm and the total friction
resistance of the moving parts is less than 1 N. The spring system shall be compressed to an initial
force of (1040±5) N(measured statistically) and the amount of spring compression point to the point where the
springs become fully closed shall be not less than 60 mm.
-Striking surface- shall be a rigid circular object, 200 mm in diameter, the face of which has a convex
spherical curvature of 300 mm radius with a 12 mm front edge radius
d.On/Off switch, machine can be operated manually
