Automobile Association British Industrial Truck Association British Pressure Gauge Manufacturers’ Association British Rubber Manufacturers’ Association Bus and Coach Council Department of Transport Freight Transport Association Institute of Road Transport Engineers (Inc) Motor Cycle Industry’s Association of Great Britain Ltd Motor Industry Research Association National Tyre Distributors’ Association Retread Manufacturers’ Association Road Haulage Association Ltd Society of Motor Manufacturers and Traders Ltd This British Standard, having been prepared under the direction of the Automobile Standards Policy Committee, was published under the authority of the Standards Board and comes into effect on 15 February 1994 © BSI 12-1999 The following BSI references relate to the work

Subsection of this Part of BS AU 50 has been prepared under the direction of the Automobile Standards Policy Committee and is identical with ISO 10500:1991 Industrial tyres and rims — Cylindrical and conical base rubber solid tyres (metric series) — Designation, dimensions and marking, published by the International Organization for Standardization (ISO) Other Parts of this standard are: — Part 2: Wheels and rims; — Part 3: Valves; — Part 4: Rim profiles and dimensions Cross-references The Technical Committee has reviewed the provisions of ISO 286-2, ISO 468, ISO 3877-4 and ISO 4223-2 to which normative reference is made in the text and has decided that they are acceptable for use in conjunction with this standard 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 Compliance with a British Standard does not of itself confer immunity from legal obligations Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages to 6, an inside back cover and a back cover This standard has been updated (see copyright date) and may have had amendments incorporated This will be indicated in the amendment table on the inside front cover ii © BSI 12-1999 BS AU 50-1.5.6:1994 Scope This International Standard specifies the main requirements, including designations, dimensions, markings and load ratings, of the metric series of cylindrical and conical base rubber solid tyres primarily intended for industrial machines for use on prepared surfaces Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard At the time of publication, the
