Fore word

This British Standard has been prepared under the direction of the Automobile
Standards Policy Committee and supersedes BS AU 1 65: 1 977, which is
withdrawn. It establishes a standard of performance to ensure the safety of j acks
supplied with passenger cars and light vans for the purpose of changing wheels
and fitting snow chains as recommended in the vehicle manufacturer’s manual.
A British Standard does not purport to include all the necessary provisions of a
contract. Users of British Standards are responsible for their correct application.

1 S cop e

This British Standard specifies requirements for the
materials, finish and safe performance of jacks
supplied as original equipment with passenger cars
of the European Communities classification
category M1 and light vans of the European
Communities classification N1 (see Appendix A).

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.

7) do 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.

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.

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 8 ± 1 % 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.
