Full title and description

St ISO 1813-2025 — Belt drives — Electrical conductivity of antistatic belts: Characteristics and test methods. This international standard specifies requirements and test methods to determine the electrical conductivity (maximum electrical resistance) of antistatic V-ribbed belts, joined V-belts and single V-belts (including wide section and hexagonal belts), and the corresponding production-control and individual proof measurement methods.

Abstract

ISO 1813:2025 defines the characteristic limits and test procedures to verify that new antistatic belts intended for use where explosive atmospheres or fire risk exist are sufficiently conductive to dissipate electrical charges formed in service. It sets maximum electrical resistance criteria and describes both production control and individual proof tests to confirm compliance with those criteria.

Scope

This standard applies to new antistatic V-ribbed belts, joined V-belts and single V-belts (including wide section and hexagonal belts) intended for use where there is a risk from explosive atmospheres or fire. It specifies maximum allowable electrical resistance values and the test methods for production control and individual verification to ensure belts dissipate electrostatic charge in service. The 2025 edition replaces earlier editions (including the 2014 edition) as the current normative document for these tests.

Key topics and requirements

• Definition of antistatic belt types covered (endless V‑ribbed, joined V‑belts, single V‑belts including wide section and hexagonal shapes).
• Maximum electrical resistance limits to qualify as antistatic for use in hazardous/fire-risk environments.
• Standardized test procedures for measuring electrical resistance (production control and individual proof tests).
• Requirements for test specimen preparation, measurement conditions and reporting of results to ensure repeatability.
• Conformity and acceptance rules for manufacturers and testing laboratories.

Typical use and users

Typical users include belt manufacturers, product design and quality engineers in power transmission and industrial drive sectors, third‑party testing and certification laboratories, procurement and safety engineers in industries where explosive atmospheres may occur (e.g., mining, petrochemical, grain handling), and standards and compliance specialists responsible for component selection in safety‑critical applications.

Related standards

ISO 1813:2025 is the current revision in a sequence of ISO 1813 publications. It supersedes ISO 1813:2014 (Edition 4, withdrawn) and earlier editions from 1998 and 1979; those earlier versions addressed similar test methods and limits for antistatic V‑belts and were later revised and consolidated into the 2025 edition. For related belt‑drive standards and test methods, consult other ISO/TC 41 publications covering belt dimensions, performance and testing.
