This document specifies the designations, contours and dimensions of drop-centre (one-piece) rims for use on trucks and buses. The rim dimensions are those rim contour dimensions necessary for mounting and fitment of the tyre to the rim. Tyre designations, dimensions and load ratings are given in ISO 4209‑1.

This document specifies requirements for five types of hose and hose assembly used in automobile power-steering systems, the five types differing in their pressure ratings and volumetric expansion. They are for use with fluids in the temperature range −40 °C to +135 °C. This document is based on performance tests. In order to take account of technological developments, no requirements are included for specific materials, detailed construction or manufacturing methods.

ISO 3894:2015 specifies two laboratory methods for testing certain essential strength characteristics of disc wheels intended for road use on commercial vehicles, buses, trailers, and multipurpose passenger vehicles, as defined in ISO 3833. The test methods are ? dynamic cornering fatigue test and ? dynamic radial fatigue test.

ISO 3006:2015 specifies two laboratory methods for testing certain essential fatigue strength characteristics of wheels intended for road use on passenger cars as defined in ISO 3833. The test methods are a) dynamic cornering fatigue test; b) dynamic radial fatigue test.

ISO 4000-2:2013 specifies the designation, contour and dimensions of 5° tapered (drop-centre) rims primarily intended for passenger cars.

This International Standard specifies test methods and performance requirements for ensuring proper wheel or rim assembly on road vehicles by means of hexagonal nuts with a flat seating captive washer used with 18 mm, 20 mm and 22 mm studs. It is applicable to commercial vehicles as defined in ISO 3833 and to those nuts as specified in ISO 7575. It is not applicable to fasteners for less common or special applications.

ISO 4107:2010 specifies the dimensions necessary for the attachment of a commercial road vehicle wheel on the hub of the vehicle whose fixing has six, eight or ten stud holes. ISO 4107:2010 considers the flat attachment type with centring on central bore, which is the recommended type for future equipment. Other types are currently in use. The specifications do not imply that the wheel is interchangeable from one vehicle to another.

ISO 13988:2008 specifies procedures and minimum performance requirements for testing without tyres the retention of clip balance weights for use on wheels for passenger vehicles. It also specifies general features for configurations of clip balance weights and rim flanges for light alloy and steel wheels intended for use on passenger cars. Alternative materials and geometries can be considered in the future.

ISO 16833:2006 defines criteria that characterise geometrical uniformity of wheels, and describes principles of measurements of these criteria.

ISO 7141:2005 specifies a laboratory test procedure to evaluate the axial (lateral) kerb impact collision properties of a wheel manufactured either wholly or partly of light alloys. It is intended for passenger car applications, and special vehicle applications where the wheel may impact the kerb, with the purpose of screening and/or quality control of the wheel.

ISO 15172:2005 specifies a test method to evaluate the strength of the nut seat of wheels intended for use on passenger cars, light trucks and multi-purpose vehicles. While this test ensures the minimum strength of the nut seat, the wheel must also have a degree of flexibility to allow torque retention. This test evaluates the axial strength of the nut seat. In addition, an informative annex provides recommended bearing area to ensure enough strength for the rotational force in tightening a nut ...view more

ISO 14400:2005 specifies requirements for the use, and general maintenance and safety of wheels and rims, and defines their out-of-service conditions, such as cracked, worn and bent wheels. It is applicable to wheels intended for use on road vehicles as defined in ISO 3833, excepting mopeds and motorcycles, and including multi-piece wheels for trucks.

Specifies the nominal dimensions and tolerances which affect interchangeability as well as designation. Dimensions and tolerances of the mating parts, i.e. type T cross-tooth gearbox flanges, are specified in ISO 8667.

Specifies the essential dimensions of hexagon nuts with a flat seat captive washer for 18 mm, 20 mm and 22 mm studs.

Specifies the nominal dimensions and tolerances which affect interchangeability and appropriate designation.
