Conveyor belts with textile carcass - Widths and lengths
Conveyor belts with textile carcass - Widths and lengths
This International Standard specifies the widths and lengths of conveyor belts with a textile carcass. It also specifies the corresponding tolerances. It is not applicable to light conveyor belts as described in ISO 21183-1, as tolerances on the widths and lengths of cut light conveyor belts are given in ISO 15147.
Courroies transporteuses à carcasse textile - Largeurs et longueurs
L'ISO 251:2012 spécifie les largeurs et les longueurs des courroies transporteuses à carcasse textile. Elle spécifie également les tolérances correspondantes.
Elle n'est pas applicable aux courroies transporteuses légères telles que décrites dans l'ISO 21183-1, puisque les tolérances sur les largeurs et les longueurs des courroies transporteuses légères à bords tranchés sont données dans l'ISO 15147.
Naprave za kontinuirni transport - Trakovi tračnih transporterjev s tekstilnimi vložki - Širine in dolžine
Ta mednarodni standard določa širine in dolžine trakov tračnih transporterjev s trupom iz tekstila. Določa tudi ustrezne tolerance. Ne uporablja se za lahke trakove tračnih transporterjev, opisane v standardu ISO 21183-1, ker so tolerance glede širine in dolžine izrezanih lahkih trakov tračnih transporterjev podane v standardu ISO 15147.

Overview
ISO 251:2012 - "Conveyor belts with textile carcass - Widths and lengths" is an international standard that specifies nominal widths and permissible tolerances for textile‑carcass conveyor belts. It also defines tolerances on belt lengths measured without tension and clarifies that belt lengths themselves are not standardized. This edition (4th, 2012) replaces ISO 251:2003.
Key topics and technical requirements
- Nominal widths and width tolerances for open (cut‑edge) textile carcass conveyor belts are specified in a list of standard sizes. Examples include:
- 300 mm ±5 mm
- 400 mm ±5 mm
- 500 mm ±5 mm
- 600 mm ±6 mm
- 800 mm ±8 mm
- 1000 mm ±10 mm
- 1600 mm ±16 mm
- 2000 mm ±20 mm
- 3000 mm ±30 mm
- 3200 mm ±32 mm (Full nominal width table and tolerances are given in the standard.)
- Length tolerances (measured without tension) are given for belts without ends (endless belts) by length ranges:
- ≤ 15 m: ±50 mm
15 m but ≤20 m: ±75 mm
20 m: ±0.5% of the belt length in metres
- Open belt length tolerances (for belts supplied as open lengths or in multiple lengths) are addressed in a separate table; tolerances depend on the delivery mode (single length or multiple lengths). Refer to ISO 251:2012 for the full treatment and exact allowable deviations.
- Scope exclusions: The standard does not apply to light conveyor belts covered by ISO 21183‑1; tolerances for some light cut‑edge belts are given in ISO 15147.
Practical applications
- Procurement and specification: Use ISO 251:2012 to define acceptable belt widths and length tolerances in purchase orders and technical specifications.
- Manufacturing and quality control: Belt manufacturers apply the nominal widths and tolerance limits during production, cutting and inspection.
- Installation and maintenance: Installers and maintenance teams use the tolerances to assess acceptance, splicing accuracy and replacement suitability.
- Conveyor system design: Engineers incorporate standardized widths and realistic length tolerances when designing belt paths, pulley widths and splicing procedures.
Who uses this standard
- Conveyor belt manufacturers
- OEMs and system integrators
- Procurement and quality assurance teams
- Mechanical and materials engineers in bulk handling, mining, logistics and manufacturing sectors
- Inspection and testing laboratories

Avant-propos
L’ISO (Organisation internationale de normalisation) est une fédération mondiale d’organismes nationaux de
normalisation (comités membres de l’ISO). L’élaboration des Normes internationales est en général confiée aux
comités techniques de l’ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du comité
technique créé à cet effet. Les organisations internationales, gouvernementales et non gouvernementales,
en liaison avec l’ISO participent également aux travaux. L’ISO collabore étroitement avec la Commission
électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI, Partie 2.
La tâche principale des comités techniques est d’élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur publication
comme Normes internationales requiert l’approbation de 75 % au moins des comités membres votants.
L’attention est appelée sur le fait que certains des éléments du présent document peuvent faire l’objet de droits
de propriété intellectuelle ou de droits analogues. L’ISO ne saurait être tenue pour responsable de ne pas avoir
identifié de tels droits de propriété et averti de leur existence.
L’ISO 251 a été élaborée par le comité technique ISO/TC 41, Poulies et courroies (y compris les courroies
trapézoïdales), sous-comité SC 3, Courroies transporteuses.
