ISO 14890:2026

Overview

ISO 14890:2026 is an internationally recognized standard developed by ISO for conveyor belts. This standard specifies the requirements for rubber- or plastics-covered conveyor belts of textile construction designed for general surface use. It covers both flat and troughed idler applications, ensuring reliable performance and uniform quality across industries. This document is not applicable to light conveyor belts, as defined in ISO 21183-1.

By providing clear guidelines for the designation, construction, tolerances, and performance characteristics of textile conveyor belts, ISO 14890:2026 supports the design, selection, and procurement of belts that ensure efficiency and safety in material conveying systems.

Key Topics

• Scope of Application: Focuses on conveyor belts with textile carcasses covered in rubber or plastics for bulk material handling, excluding light-duty belts.
• Belt Designation: Details the method to designate belts based on length, width, thickness, textile material, tensile strength, number of plies, cover class, and safety category.
• Construction Requirements: Specifies carcass construction with options for multi-ply, duo-ply, mono-ply, and solid woven belts, as well as the placement of breakers and pile components.
• Dimensional Requirements: Defines tolerances for length, width, total belt thickness, and cover thickness to ensure compatibility and quality.
• Physical Properties: Establishes criteria for tensile strength, elongation, adhesion, and troughability as tested by referenced ISO methods.
• Joint Specifications: Regulates the location, spacing, and number of transverse and longitudinal fabric joints for durability and operational reliability.
• Identification and Marking: Outlines the minimum manufacturer and product information to be displayed for traceability and compliance.

Applications

ISO 14890:2026 is essential in sectors where robust bulk material conveyance is critical, including:

• Mining and Quarrying: Bulk transport of minerals, aggregates, and ores using textile-reinforced conveyor belts.
• Industrial Processing: Handling of bulk chemicals, agricultural products, and foodstuffs along automated production lines.
• Construction: Movement of sand, gravel, cement, and building materials on site or within plants.
• Warehouse and Distribution: General material handling on flat or troughed conveyor systems.
• Harbor and Port Operations: Conveyance of bulk shipments like grains, coal, or raw materials for loading or unloading.

Exacting standards for mechanical properties and dimensional tolerances contribute to enhanced operational safety, reduced downtime, and lower maintenance costs across these industries.
