EN 13531:2001+A1:2008 (E) 9 5 Test method and facilities 5.1 General The requirement for TOPS is energy absorption in the lateral direction. There are limitations on deflections under the lateral loading. The energy requirements and limitations on deflection (DLV) under lateral loading are intended to assure that the TOPS will not significantly deform while retaining significant capability to withstand impact in the tip. The evaluation procedure will not necessarily duplicate structural deformations due to a given actual tip-over. However, it is expected that crush protection for a seat-belted operator will be assured under at least the following conditions: a flat hard soil surface; 90° of tip-over about the swing frame longitudinal axis without losing contact with the surface. 5.2 Instrumentation Systems used to measure mass, force and deflection shall be capable of meeting the requirements of ISO 9248:1992. 5.3 Test facilities Fixtures shall be adequate to secure the TOPS/swing frame assembly to a bedplate and to apply the required lateral load as determined by the formulae given in Table 1. 5.4 TOPS/swing frame assembly and attachment to bedplate 5.4.1 The TOPS shall be attached to the swing frame as it would be on an operating machine (see Figure 4). A complete swing frame is not required for the evaluation. However, the swing frame and mounted TOPS test specimen shall represent the structural configuration of an operating installation. All normally detachable windows, panels, doors, and other non-structural elements shall be removed so that they do not contribute to, nor detract from, the structural evaluation. 5.4.2 The TOPS/swing frame assembly shall be secured to the bedplate so that the members connecting the assembly and bedplate experience minimal deflection during testing. The TOPS/swing frame assembly shall not receive any support from the bedplate, other than that due to the initial attachment. 5.4.3 The test shall be conducted with any machine/ground suspension elements blocked externally so that they do not contribute to the load-deflection behaviour of the test specimen. Suspension elements used to attach the TOPS to the machine frame
