Overview
SIST EN ISO 14890:2026 – Conveyor belts – Specification for rubber- or plastics-covered conveyor belts of textile construction for general use sets out the requirements for conveyor belts with textile carcasses and rubber or plastics covers, intended for general surface use on flat or troughed idlers. This standard is essential for manufacturers, suppliers, and users in industries where reliable and standardized conveyor belting solutions are crucial for efficient material handling.
EN ISO 14890 does not apply to light conveyor belts as described in ISO 21183-1, focusing instead on heavier general-purpose belting suitable for a wide range of industrial applications. Developed by CEN in partnership with ISO, this standard harmonizes product requirements, ensuring safety, quality, and interoperability across international markets.
Key Topics
SIST EN ISO 14890:2026 addresses a comprehensive set of characteristics and requirements for textile-based conveyor belts, including:
-
Designation and Ordering: Guidance on how belts should be designated for specification and procurement, detailing belt length, width, type, cover thickness, tensile strength, number of plies, textile materials, and safety category as per EN 12882.
-
Construction and Materials:
- Types of textile carcass: mono-ply, duo-ply, multi-ply, and solid woven belts.
- Cover types: rubber or plastics, including thickness and classification according to ISO 10247.
- Requirements for breaker layers and fabric piles.
-
Dimensions and Tolerances:
- Specified tolerances on belt length, width, thickness, and cover thickness.
- Guidance for measuring and verifying belt dimensions and testing procedures.
-
Mechanical Properties:
- Minimum values and testing methods for full thickness tensile strength, elongation at reference force, as well as adhesion strengths between plies and between cover and carcass.
- Troughability requirements according to ISO 703, ensuring belts are suitable for use on troughed idlers.
-
Joints and Fabrication:
- Permitted numbers and locations of longitudinal and transverse joints in multi-ply belts.
- Restrictions for joints in mono-ply, duo-ply, and solid woven belts.
-
Identification and Marking:
- Requirements for marking the belt with manufacturer’s name, compliance, date, and safety category.
Applications
SIST EN ISO 14890:2026 is widely applicable across industries where robust and reliable conveyor systems are essential. Its standardized approach offers significant advantages in sectors such as:
- Mining and Quarrying: For the transport of aggregates, ores, and coal.
- Cement and Construction: Moving raw materials, clinker, and finished goods.
- Bulk Material Handling: Grain, fertilizer, chemicals, and waste handling facilities.
- General Manufacturing: Production and assembly lines requiring consistent, high-performance belt systems.
The standard streamlines the specification, procurement, and maintenance of conveyor belts, enhancing compatibility in international projects and supporting operational safety and efficiency.
