Impact test steel cylinders and steel liners
Impact test. The test according to this paragraph is not to be carried out for devices integrated in the bodywork of the vehicle and providing a frontal deflecting area of an angle not more than 45° measured in relation to the longitudinal median plane of the vehicle, or devices not protruding more than 100 mm measured beyond the circumscribing bodywork of the vehicle according to Regulation No. 26.
6.1.3.2.1. Description of the test rig
6.1.3.2.1.1. The test rig consists of a pendulum capable of swinging about two horizontal axes at right angles to each other, one of which is perpendicular to the plane containing the "release" trajectory of the pendulum. The end of the pendulum comprises a hammer formed by a rigid sphere with a diameter of 165 ± 1 mm having a 5 mm thick rubber covering of Shore A hardness 50. A device is provided which permits determination of the maximum angle assumed by the arm in the plane of release.
Impact test. The impact properties of welded steel in the inner vessel shall be tested in accordance with EN 1251-2:2000 and EN 10045-1:1990.

6.1.3.2.1.2. The centre of percussion of the pendulum coincides with the centre of the sphere, which forms the hammer. It is at a distance l from the axis of oscillation in the release plane, which is equal to 1 m ± 5 mm. The reduced mass of the pendulum is mo = 6.8 ± 0.05
Impact test. The test according to this paragraph is not to be carried out for
(a) exterior devices not projecting beyond the overall width and length of the vehicle and providing a frontal deflecting area of an angle not more than 45° measured in relation to the longitudinal median plane of the vehicle, or
(b) devices not protruding more than 100 mm measured at the attachment point beyond the circumscribing external original surface of the vehicle according to Regulation No. 26. See Annex 9. "
6.3.2.2.2.1. amend to read:
6.3.2.2.2.1. Devices for indirect vision shall be positioned on the pendulum impact rig in such a way that the axes which are horizontal and vertical when the device for indirect vision is installed on a vehicle in accordance with the applicant's mounting instructions are in a similar position;"
Impact test. 8.2.1. Description of the test device:
8.2.1.1. The test device shall consist of a pendulum capable of swinging about two horizontal axes at right angles to each other, one of which is perpendicular to the front plane containing the "release" trajectory of the pendulum. The end of the pendulum shall comprise a hammer formed by a rigid sphere with a diameter of 165 + 1 mm and having a 5 mm-thick rubber covering of Shore A 50 hardness. A device shall be provided which permits determination of the maximum angle assumed by the arm in the plane of release. There shall be a support firmly fixed to the structure supporting the pendulum which serves to hold the specimens in compliance with the impact requirements stipulated in paragraph 8.2.2.6. below. Figure 1 below gives the dimensions of the test facility and the special design specifications.
8.2.1.2. The centre of percussion of the pendulum shall coincide with the centre of the sphere which forms the hammer. It is at a distance "1" from the axis of oscillation in the release plane which is equal to 1 m +5 mm. The reduced mass of the pendulum to its centre of percussion is mo = 6.8 +0.05
Impact test. 10.1 Use a hammer or impact device coupled with a suitable backing block to support the article to be tested to deform the sample. Reproducible results am more easily obtained by the use of a suitably modified impact tester where the force is reproducible and the impact head contour is in the form of a 5-mm diameter ball, shock loaded by a failing weight or swinging pendulum weight. The severity of the test may be altered by changing the load and diameter of the ball. Exfoliation or blisters in and around indentations are evidence of inadequate adhesion.
10.2 This test is sometimes difficult to interpret. Soft and ductile coatings are generally not suited for evaluation.
Impact test. 3.5.1.1. The resistance of door locks to inertia loads may be determined either by dynamic or by analytical means. In the case of a dynamic test, the test vehicle itself or the simulated structure shall be secured to a chassis with the door lock system in the fully latched position. An acceleration of 30-36 g, shall be applied to the chassis for a period of at least 30 milliseconds in a forward direction in parallel to the vehicle longitudinal axis as well as in a direction of the door opening that is perpendicular to the above described first direction.
3.5.1.2. When equipped with a lock device (a device to secure the latch and striker in a locked position), ensure that the device does not come into action during the tests.
3.5.1.3. The instrumentation shall permit the recording of the acceleration value without distortion for the phenomena having frequencies up to 100 hertz, the permissible distortion being: Db to 60 Hz and +05 Db to 100 Hz. 1/ - 1 - 4
