Test Methods and Specimens8.1 Introduction:8.1.1 Three basic vibratory methods exist:8.1.1.1 Forced vibration of a nonresonant system involving only the specimen,8.1.1.2 Free vibration of a resonant system involving the specimen and a mass, and8.1.1.3 Forced vibration of the above resonant system.8.1.2 The first and third can be broken down further into two kinds of apparatus, those…

5 Apparatus 5.1 Impact surface, which should be either: a) a plane inclined to the vertical at 10° ± 1° (for the inclined plane test), or b) a plane vertical to within 1° (for the horizontal or pendulum test). The dimensions of the impact surface shall be greater than those of the impacting face, or…

3 Apparatus 3.1 GeneralTheapparatus shall consist of a jig or any other arrangement capable of: a)applying the specified diametric and/or angular deflection; b)applying the specified test pressure(s), positive or negative; c)maintaining the test assembly in the required position throughout the test; d)resisting the forces resulting from the mass of the water in the test assembly…
