The steel anvil (100 mm diameter \u00d7 70 mm height) is screwed onto the top of a steel block (230 mm length \u00d7 250 mm width \u00d7 200 mm height) with a base (450 mm length \u00d7 450 mm width \u00d7 60 mm height). A column of seamless drawn steel tubing is fixed in a bracket that is bolted to the back of the steel block. The fallhammer is fixed with 4 anchoring screws on a solid concrete block (60 cm \u00d7 60 cm) in such a way that the guides are exactly vertical and the drop weight is easily guided. Drop weights are made of solid steel and are available, for example, in 5 kg and 10 kg weights. The striking head of each weight is made of hardened steel, HRC 60 to 63, and has a minimum diameter of 25 mm.<\/p>\n<p>The test result is assessed as positive if an explosion (a bang and\/or ignition is equivalent to an explosion) occurs with the apparatus described in at least one test.<\/p>\n<\/div>\n<\/div>\n<p>[\/vc_column_text][vc_row_inner rt_row_style=&#8221;global-style&#8221;

The porcelain plate is fixed in a carriage which runs in two guides. The carriage is connected to an electric motor via a connecting rod, an eccentric cam and suitable gearing such that the porcelain plate is moved, once only, backwards and forwards beneath the porcelain peg for a distance of 10 mm. The porcelain peg can be loaded with 120 or 360 N, for example.<\/p>\n<p>The flat porcelain plates are made of pure technical white porcelain (roughness 9 \u03bcm to 32 \u03bcm) and have the dimensions 25 mm (length) \u00d7 25 mm (width) \u00d7 5 mm (height). The cylindrical porcelain peg is also made of pure technical white porcelain. It is 15 mm long, has a diameter of 10 mm and a rough spherical end face with a radius of curvature of 10 mm.<\/p>\n<p>The test result is considered positive if an explosion occurs at least once in any of the tests with the specified friction apparatus. Crackling and\/or a bang, sparking or flame is equivalent to an explosion. Decomposition (change of color or odor) is not considered an explosion.<\/p>\n<\/div>\n<\/div>\n<p>[\/vc_column_text][vc_row_inner rt_row_style=&#8221;global-style&#8221; rt_bg_custom_alignment=&#8221;top&#8221;
