is replaced by: The accelerometers shall be mounted at a single point (P) on the tunnel close to the vertical projection of vehicle centre of mass of the undeformed vehicle, but no further than 70 mm longitudinally and 40 mm laterally. Measurements made before the publication of the present standard, with accelerometers fixed to an installation close to the centre of mass are accepted. 6.2 Frequency requirements The following new requirement has been introduced: Since the data will be filtered by recursive (Butterworth) filters, more data should be collected than is specifically required by the analysis. A recursive filter always produces "starting transients" at the beginning and end of the data, and requires time to "settle down". An additional 500 ms of data shall be collected at the beginning and end of the data; this extra data can then be discarded after filtering. 6.3 Compensation for instrumentation displaced from the vehicle centre of mass The procedure has been extended also to the cases of non-null roll angle and roll velocity and when the three points Q1, Q2, P (P1, P2, P in the 1998 text) are aligned along any straight line. 8.1 Severity Indices The requirement for the index PHD (Post impact Head Deceleration) has been removed. ASI and THIV are required. 8.1.1 Summary of the procedure to compute ASI In the procedure to compute ASI, averaging of the three components of the acceleration over a moving window of 50 ms has been replaced by filtering with a four-pole phaseless Butterworth digital filter.
8.2 Vehicle cockpit deformation index (VCDI) 8.2.2 Location of the deformation The prefix ‘ND’ has been added for impacts where there is no deformation of the vehicle cockpit. 8.2.3 Extent of the deformation "The sub-index 3 has been added for reductions greater than 20 %, or measurements which cannot be taken due to the deformation of the vehicle." According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. SIST EN 1317-1:2010

This European Standard is a revision of EN 1317-1:1998. The standard identifies test methods and impact test acceptance criteria that the products for road restraint systems need to meet to demonstrate compliance with the requirements, given in EN 1317-5 and/or prEN 1317-6. The design specification, for road restraint systems entered in the test report, identify important functional site conditions in respect of the test installation. The performance range of the products for road restraint systems, designated in this standard, enables national and local authorities to recognize and specify the performance class to be deployed. Annexes A and B give informative explanation of the measurement of the severity index ASI and vehicle acceleration. SIST EN 1317-1:2010
