Full title and description

Textile conveyor belts — Full thickness tensile strength, elongation at break and elongation at the reference load — Test method (ISO 283:2023). This international standard specifies a laboratory test method to determine full-thickness tensile strength and elongation characteristics of conveyor belts with a textile carcass, in the longitudinal direction and (where requested) the transverse direction.

Abstract

ISO 283:2023 defines procedures for preparing specimens, conditioning, performing tensile tests on full-thickness samples, recording elongation at a specified reference force and at break, and calculating/reporting full-thickness tensile strength and elongation values. The method excludes light conveyor belts as described in ISO 21183‑1.

Scope

ISO 283:2023 specifies a test method for determination of full-thickness tensile strength in the longitudinal direction, and for determining elongation at a defined reference force and at break, for conveyor belts having a textile carcass. The method can also be applied to determine transverse tensile strength and elongation at break when requested by the purchaser. The standard explicitly excludes light conveyor belts; those are covered by the ISO 21183 series and related light-belt test standards.

Key topics and requirements

• Specimen preparation and full-thickness sampling of conveyor belts with textile carcass.
• Conditioning requirements prior to testing (temperature/humidity control).
• Tensile test procedure for longitudinal (and optionally transverse) full-thickness tensile strength.
• Measurement and reporting of elongation at the reference load and elongation at break.
• Calculation of tensile strength (force per unit width) and presentation of results for purchaser/manufacturer agreements.
• Notes on exclusions and applicability (not for light conveyor belts covered elsewhere).

Typical use and users

Used by conveyor-belt manufacturers, independent testing laboratories, quality and R&D engineers, procurement/specification teams, and conformity assessors to verify tensile and elongation performance of textile carcass conveyor belts and to provide comparable test results for contract specification and acceptance testing.

Related standards

Key related documents include the previous edition ISO 283:2015 (withdrawn and replaced by the 2023 edition) and the ISO 21183 series (light conveyor belts — principal characteristics and related test methods) which defines the light-belt category excluded from ISO 283. Standards from ISO/TC 41/SC 3 (conveyor belts) provide complementary test methods and definitions.

FAQ

Q: What is this standard?

A: ISO 283:2023 is an ISO international standard defining a laboratory test method for measuring full-thickness tensile strength and elongation (at a reference load and at break) of conveyor belts with a textile carcass.

Q: What does it cover?

A: It covers specimen preparation, conditioning, tensile testing procedures, measurement of elongation at specified loads and at break, calculation of tensile strength per unit width, and reporting of results. It does not apply to light conveyor belts (see ISO 21183‑1).

Q: Who typically uses it?

A: Conveyor-belt manufacturers, independent test laboratories, product and quality engineers, procurement/specification teams, and conformity assessment bodies use the standard to produce reproducible tensile/elongation data for material selection, quality control, and contract acceptance.

Q: Is it current or superseded?

A: ISO 283:2023 is the current published edition (Edition 5, March 2023) and replaces ISO 283:2015, which has been withdrawn.

Q: Is it part of a series?

A: Yes. ISO 283 is part of the body of standards maintained by ISO/TC 41/SC 3 on conveyor belts; related documents include the ISO 21183 series for light conveyor belts and other ISO/TC 41 test-method standards.

Q: What are the key keywords?

A: conveyor belt, textile carcass, tensile strength, elongation, reference load, full-thickness test, ISO 283.
