This Subsection forms part of Section 5 of this British Standard. This Subsection specifies rim profiles and dimensio
10、ns suitable for use with the code-designated series tyres specified in BSAU50-1.5.1. Requirements for rims for metric series tyres are specified in the other Subsections of Section 5. Part 4 of this standard is concerned with rim profiles and dimensions. Other Parts are as follows: Part 1: Tyres; Pa
11、rt 2: Wheels and rims; Part 3: Valves. Other Sections of Part 4 are as follows: Section 1: Passenger car rims; Section 2: Commercial vehicle rims; Section 3: Off-the-road vehicle rims; Section 4: Agricultural vehicle rims; Section 5: Industrial vehicle rims; Section 6: Motor cycle rims; Section 7: M
12、oped rims. 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

14、95 BSI 09-1999 1 1 Scope This Subsection of BSAU50-4 specifies contours and dimensions of rims for use with code-designated series tyres used on industrial vehicles. Requirements for such tyres are specified in BSAU50-1.5.1:1994. Requirements for rim construction and workmanship are specified in BSA
15、U50-2.0:1979. SAFETY NOTE. The wheel manufacturer should also be consulted to determine whether the rim and wheel is of sufficient strength for the intended service. In particular, care should be taken to ensure that the wheel will withstand the maximum pressure of any tyre that can be fitted in acc
16、ordance with BSAU50-1.5.1:1994. This pressure may exceed1000 kPa (10bar) for both diagonal and radial tyres. 2 References 2.1 Normative reference This Subsection of BS AU50-4 incorporates, by dated or undated reference, provisions from another publication. This normative reference is made at the app
