The impact value is expressed in joules per square metre. 4 Principle The impact value is determined by using a pendulum-type impact machine on a metal-to-metal or wood-to-wood specimen. 5 Apparatus 5.1 Pendulum-type impact machine, with a impact-head velocity of 3,4 m/s, comprising the elements specified in 5.1 .1 to 5.1 .3. 5.1.1 Impact head, with a flat striking face slightly wider than the specimen and aligned to strike the specimen full- face. 5.1.2 Specimen-holding fixture, as shown in figure 1 . The fixture illustrated is not always suitable for use with all impact machines and vices. Dimensions and design of the fixture may be varied as required for adaptation to machines and vices available, provided the following general requirements are met: The fixture shall be machined from a solid piece of steel and solidly bolted to the base of the testing machine. Corners shall...
