Scope. This standard specifies limits,for the displacement into the windshield,area of motor vehicle components,during a crash.,S2. Purpose. The purpose of this,standard is to reduce crash injuries and,fatalities that result from occupants,contacting vehicle components displaced,near or through the windshield.,S3. Application. This standard applies,to passenger cars and to multipurpose,passenger vehicles, trucks and buses of,4,536 kilograms or less gross vehicle,weight rating.

Definitions. Daylight Opening,(DLO) means the maximum unobstructed,opening through the glazing,surface, including reveal or garnish,moldings adjoining the surface, as,measured parallel to the outer surface,of the glazing material.,S5. Requirement. When the vehicle,travelling longitudinally forward at,any speed up to and including 48 km/h,impacts a fixed collision barrier that is,perpendicular to the line of travel of,the vehicle, under the conditions of S7,no part of the vehicle outside the occupant,compartment, except windshield,molding and other components designed,to be normally in contact with,the windshield, shall penetrate the protected,zone template, affixed according,to S6, to a depth of more than 6 mm,and no such part of a vehicle shall penetrate,the inner surface of that portion,of the windshield, within the DLO,below the protected zone defined in S6.,S6. Protected zone template.,S6.1 The lower edge of the protected,zone is determined by the following,procedure (See Figure 1).,(a) Place a 165 mm diameter rigid,sphere, with a mass of 6.8 kg in a position,such that it simultaneously contacts,the inner surface of the windshield,glazing and the surface of the instrument,panel, including padding. If,any accessories or equipment such as,the steering control system obstruct,positioning of the sphere, remove them,for the purposes of this procedure.,(b) Draw the locus of points on the,inner surface of the windshield,contactable by the sphere across the,width of the instrument panel. From,the outermost contactable points, extend,the locus line horizontally to the,edges of the glazing material.,(c) Draw a line on the inner surface,of the windshield below and 13 mm distant,from the locus line.,(d) The lower edge of the protected,zone is the longitudinal projection onto,the outer surface of the windshield of,the line determined in S6.1(c).,S6.2 The protected zone is the space,enclosed by the following surfaces, as,shown in Figure 1:,(a) The outer surface of the windshield,in its precrash configuration.,(b) The locus of points 76 mm outward,along perpendiculars drawn to,each point on the outer surface of the,windshield.,(c) The locus of lines forming a 45°,angle with the outer surface of the,windshield at each point along the top,and side edges of the outer surface of,the windshield and the lower edge of,the protected zone determined in S6.1,in the plane perpendicular to the edge,at that point.,S6.3 A template is cut or formed,from Styrofoam, type DB, cut cell, to,the dimensions of the zone as determined,in S6.2. The template is affixed,to the windshield so that it delineates,the protected zone and remains affixed,throughout the crash test.,S7. Test conditions. The requirement,of S5. shall be met under the following,conditions:,S7.1 The protected zone template is,affixed to the windshield in the manner,described in S6.,S7.2 The hood, hood latches, and,any other hood retention components,are engaged prior to the barrier crash.,S7.3 Adjustable cowl tops or other,adjustable panels in front of the windshield,are in the position used under,normal operating conditions when,windshield wiping systems are not in,use.,S7.4 The parking brake is disengaged,and the transmission is in neutral.,S7.5 Tires are inflated to the vehicle,manufacturer’s specifications.,S7.6 The fuel tank is filled to any,level from 90 to 95 per cent of capacity.,S7.7 The vehicle, including test devices,and instrumentation, is loaded as,follows:,(a) Except as specified in S7.6, a passenger,car is loaded to its unloaded vehicle,weight plus i……
