Overview
ISO 10500:1991 is an international standard developed by the International Organization for Standardization (ISO) that specifies requirements for industrial rubber solid tyres and rims with cylindrical and conical bases, part of the metric series. This standard focuses on the designation, dimensions, and marking of solid rubber tyres used mainly in material handling equipment operating on prepared surfaces. It addresses key technical parameters such as tyre sizing, load capacities, and identification markings to ensure safety, compatibility, and performance consistency in industrial environments.
Key Topics
-
Tyre Designation
The standard defines systematic tyre designation methods for both cylindrical base and conical base solid rubber tyres. Designations include:
- Outer diameter (overall tyre size)
- Nominal base width
- Nominal rim diameter
For example:
260 x 125/60 for cylindrical base tyres and additional markings for conical bases.
-
Dimensions
Detailed dimensional requirements cover:
- Outer diameter and base width of the tyre
- Rim diameter and rim profiling for correct tyre fitment
The standard provides tables of nominal dimensions with tolerance values aligned with ISO 286-2. Rim profiles and chamfering recommendations facilitate mounting and secure tyre seating.
-
Marking Requirements
To ensure traceability and correct application, tyres must be marked with:
- Designation per the standard
- Symbols KM or KS identifying conical base tyres with specific rim types
- Maximum permissible speed where relevant
Markings are placed on the tyre sidewall near dimensional data for clear visibility.
-
Load Capacity Ratings
Load capacities listed refer to forklift trucks and similar equipment, specifying load-bearing capacity according to tyre dimensions and application speed limits. The standard facilitates understanding of load ratings for:
- Single and dual tyre mounting configurations
- Various tyre sizes and base profiles
Ensuring operational safety and longevity.
-
Rim Compatibility
The standard specifies rim profiles corresponding to cylindrical and conical base tyres with detailed geometric and tolerance information. This compatibility ensures secure tyre mounting and stable performance.
Applications
ISO 10500:1991 is primarily applied in industries using material handling equipment such as forklifts, stackers, and industrial trucks. Key practical benefits include:
-
Tyre Selection and Procurement
Manufacturers and maintenance teams use this standard to select appropriately sized solid rubber tyres that fit specified rims and meet load and speed criteria.
-
Safety and Compliance
Adherence to the marking and load capacity provisions aids in compliance with operational safety requirements, reducing risks of tyre failure in industrial settings.
-
Interchangeability and Standardization
By standardizing tyre designations and dimensions across manufacturers, it simplifies replacement tyre sourcing and supports global trade.
-
Asset Management
Correct tyre marking assists in identification during inspections, maintenance scheduling, and record keeping.
Related Standards
ISO 10500:1991 references and complements multiple ISO standards for complete industrial tyre and rim standardization:
- ISO 4223-2:1991: Definitions for terms related to solid tyres.
- ISO 3877-4:1984: Terms equivalent to solid tyre terminology.
- ISO 286-2:1988: ISO system for tolerances and fits applicable to rim diameters and tyre dimensions.
- ISO 468:1982: Surface roughness specifications relevant to rim and tyre contact surfaces.
These related standards collectively ensure consistency and compatibility within the tyre manufacturing, specification, and operational landscape.
