passenger cars of the European Communities classification category M1 and light vans of the European Communities classification N1 (see Appendix A) Ge ne ral The jack shall be suitable for locating at the jacking points as specified by the vehicle manufacturer and shall be capable of being operated without fouling any part of the vehicle with the doors closed It shall not be possible to raise the vehicle with a jack that has been incorrectly assembled from its component parts Means shall be provided to prevent over-travel of the jack Instructions for the safe use of the jack shall be provided Written instructions for the use of the jack shall be provided in the vehicle manufacturer’s instruction manual, together with the following information 2.1 2.2 2.3 2.4 6) give consideration to advice for jacking on soft ground; 7) not run the engine when the vehicle is jacked up; 8) loosen wheel nuts slightly prior to jacking up the vehicle; 9) only use the supplied jack with the vehicle make and model marked on the jack e) When wheel changing at the roadside: 1) clean the brake drum/mounting flange before fitting a wheel; 2) screw up the wheel nuts before lowering the vehicle; 3) finally tighten the wheel nuts, to the manufacturer’s recommended torque, after lowering the vehicle f) Stow the jack in its stowing point or in a covered container in the vehicle Mate rials Strength and other essential physical properties of the component parts of the jack shall be adequate for use with the vehicle with which it is supplied All castings, which shall be in accordance with the appropriate British Standards, shall be of uniform NOTE It may be in a style compatible with the remainder of the quality, free of blow holes, porosity, hard spots, vehicle manual text shrinkage, cracks or other deleterious defects which a) The vehicle jack is only for wheel changing and might adversely affect the intended use Processes snow chain attachment (if appropriate) such as peening or plugging shall not be used on b) Do not place any part of the body under the castings or forgings for reclaiming any part of the vehicle when the vehicle is supported by the jack jack Lubricants, hydraulic fluids and paints shall alone Note that it is very dangerous for users to be compatible with seal materials, where seals are go underneath a vehicle supported only by the used vehicle jack For repair work where the user needs to go underneath, special vehicle supports are to be All cast, forged, moulded or welded parts shall be used free of sand, dirt, fins, scale, flux and other harmful c) Use chocks when stopped on a hill or cambered extraneous materials All external surfaces shall be road Seek advice on the number, position and free of burrs, fins and sharp edges At the delivery placement of chocks from the manufacturer’s stage the surfaces shall be protected against handbook Note that the jack is designed only for corrosion, and moving parts shall be lubricated as use on a gradient of less than % and a camber of necessary less than 5.5 % d) When using the vehicle jack for wheel changing at the roadside: When tested in accordance with Appendix B, the jack shall have adequate extension for use on the 1) use hazard lights; vehicle with which it is supplied 2) apply the handbrake; 3) place gears in “1” or “Reverse” on manual gear boxes, or “P” on automatic transmissions; 4) occupants should leave the vehicle; 5) place the jack at the placement position advised by the vehicle manufacturer; 2.5 Finish D ime nsions © BSI 10-1999 BS AU 65 a: 990 O p eration O ve rload When tested in accordance with the jack shall not collapse and the permanent deflection shall be It shall be possible to perform the jacking operations not more than % of the height measured at d) described in Appendix B by applying a force that shall not exceed the following values: a) 250 N for jacks operated by up and down lever The jack shall be permanently and indelibly marked action; in accordance with type 8A of BS 4781-1 and b) 125 N for all other types of jack operation BS 4781-2 The marking shall include the following information: At any point over its full travel while raising or a) the make and model of vehicle for which the lowering the vehicle, the jack mechanism shall not jack is intended; operate independently when the operating force is b) the number and date of this British Standard, removed i.e BS AU 165a:19901) ; c) a warning sign or other indication to illustrate that the operating instructions are to be found in When tested in accordance with Appendix C, the the vehicle handbook jack shall support the vehicle without the vehicle coming off the jack O p e rational e ffort D.3 D.3 Marking Accid e ntal op e ratio n S tab ility D urab ility When tested in accordance with there shall be no undue wear or permanent deformation of either the jack or the handle and the operating force measured after the tenth cycle shall differ from the fiftieth lift by not more than ± 10 % D.2 1) Marking BS AU 165a:1990 on or in relation to a product represents a manufacturer’s declaration of conformity, i.e a claim by or on behalf of the manufacturer that the product meets the requirements of the standard The accuracy of the claim is therefore solely the responsibility of the person making the claim Such a declaration is not to be confused with third party certification of conformity, which may also be desirable © BSI 10-1999 BS AU 65a:1 990 Appendix A Classification of vehicles in accordance with the Commission of the European

or having three wheels when the maximum mass exceeds t, and used for the carriage of goods Vehicles used for the carriage of goods and having a maximum mass not exceeding 3.5 t Appendix B Test for adequacy of extension of the j ack Appendix C Tests for stability Use a new jack for each of the procedures in C.2 , C.3 and C.4 C.2 Load the vehicle to the weight given in B.1 Apply the parking brake Using all available jack travel at any jacking point, apply a longitudinal force of 250 N to the vehicle in both directions separately followed by a lateral force of 250 N in both directions Apply the force approximately 60 cm above the road surface C.3 Load the vehicle to the weight given in B.1 Park the vehicle on a surface having a gradient of ± % and a camber of 5.5 ± 0.5 % Apply the parking brake and set the transmission control as instructed by the manufacturer’s manual Carry out the jacking procedure given in Appendix B first with the vehicle facing uphill and then facing downhill C.4 Load the vehicle to kerb weight and repeat stability tests C.2 and C.3 C.1 Appendix D Tests for durability and overload D.1 General Use a new jack for each of the procedures in D.2 and D.3 D.2 Durability test Carry out this test with a new jack and handle equally around the jacking points Follow the procedure given in Appendix B for 50 jacking cycles One jacking cycle consists of raising and lowering any wheel Each jacking cycle may be followed by a cooling period of not more than B.1 Load the vehicle to the manufacturer’s D.3 Overload test maximum gross vehicle weight (GVW), less 100 kilos at the driver’s position, immobilize it Carry out the procedure as follows in accordance with the manufacturer’s instructions, a) Set any available means of height adjustment and stand it on a level concrete surface or (other than that provided by the normal travel of equivalent the jack) to its highest position B.2 Locate the jack correctly at each jacking point, b) Where fitted, render the jack’s overload with the nearest tyre completely deflated to give the protection device inoperative least favourable conditions c) Raise the head cap to 66 % of its range of travel B.3 Lift the vehicle off the ground to provide d) Mount the jack on a flat, rigid surface and sufficient clearance between the ground and tyre to measure the height of that part of the load (test fit the spare wheel, for all tyre sizes specified by the rig or weight) which bears on the headcap, above vehicle manufacturer the flat, rigid surface B.4 Inflate the spare wheel tyre to the maximum e) Apply a force equal to 200 % of the vertical specified pressure force taken by the jack under the conditions of Appendix B, at the location with the highest loading Apply the test force in the same manner as the service loading f) Maintain the force for min, then remove the force g) Examine the jack for collapse, and measure the height of the load above the flat, rigid surface © BSI 10-1999 blank BS AU
