23、from entering dangerous zones or areas. The road restraint systems designated in this standard are designed to specified performance levels of containment, to redirect errant vehicles and to provide guidance for pedestrians or other road users. The objective of this standard is to provide a procedur
24、e whereby the present national standards and regulations, which currently pertain in member countries, can be harmonized to a common European Standard. Many types of road restraint systems are available; their characteristics differ both by function and by on-road use. European standardization requi
25、res common terminology in order to provide a clear understanding of the design, performance, production and construction of the various road restraint systems. This standard identifies impact test tolerances and vehicle behaviour criteria that need to be met to gain approval. The design specificatio
26、n, for road restraint systems entered in the test report, should identify the on-road site conditions under which the road restraint system should be installed. The performance range of restraint systems, designated in this standard, enables national and local authorities to recognize and specify th
27、e performance class to be deployed. The range of possible vehicular impact into an on-road road restraint system is extremely large in terms of speed, approach angle, vehicle type, vehicle performance, and other vehicle and road conditions. Consequently the actual on-road impacts which occur may var
28、y considerably from the specific standard test conditions. However, adequate implementation of the standard should identify the characteristics, in a candidate safety road restraint system, that are likely to achieve maximum safety and reject those features which are unacceptable. It is recommended
29、that this standard is reviewed within a period of five years, or following the completion of a proposed set of impact validation tests. 1 Scope This European Standard gives the definitions of the principal terms used for road vehicle restraint systems and pedestrian restraint systems in other parts
30、of this standard. It also specifies the general provisions for test methods. Informative annexes B and C give information on impact kinetic energy and vehicle acceleration. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. T
31、hese normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For und

Page 6 EN 1317-1:1998 BSI 1998 6 Measurement of the acceleration severity index (ASI) 6.1 Calculation of ASI The acceleration severity index ASI is a function of time, compute
48、d using the following equation (1): ASI(t) =(ax/a x)2+ (ay/a y)2+ (az/a z)2 (1) where: a x, a y and a z are limit values for the components of the acceleration along the body axes x, y and z; ax, ay and az are the components of the acceleration of a selected point P of the vehicle, averaged over a m
49、oving time interval d = 50 ms, so that: ax =ax dt; 1 d t t + d ay =ay dt; 1 d t t + d az =az dt.(2) 1 d t t + d The index ASI is intended to give a measure of the severity of the vehicle motion for a person seated in the proximity of point P during an impact. The average in equation (2) is actually a low pass filter, taking into account the fact that vehicle accelerations can be transmitted to the occupant body through relati
