Full title and description

ISO 9563:2015 — Belt drives — Electrical conductivity of antistatic endless synchronous belts — Characteristics and test method. This International Standard specifies the maximum and minimum electrical resistance and associated test procedures for antistatic (electrostatic-dissipative) endless and open-ended synchronous belts used where static charge accumulation could create a fire or explosion risk.

Abstract

ISO 9563:2015 gives guidelines and a production-control test method to verify that synchronous belts are sufficiently conductive to dissipate electrostatic charges formed in service. The standard applies to new belts intended for use in explosive atmospheres or other locations where fire risk exists and covers selection of electrodes and conductive coatings used in proof tests.

General information

• Status: Published (confirmed in ISO systematic review process).
• Publication date: 14 September 2015.
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 21.220.10 — Belt drives and their components.
• Edition / version: Edition 2 (2015).
• Number of pages: 6 pages.

Scope

The standard specifies electrical resistance limits and an associated test method for antistatic endless and open-ended synchronous belts. Its application is limited to new belts intended for use where dissipation of electrostatic charge is required (for example in explosive atmospheres or other fire-risk environments). It provides guidance for production-control testing and leaves the decision about batch testing frequency to national standards or contractual agreement between parties.

Key topics and requirements

• Defined maximum and minimum electrical resistance values for antistatic synchronous belts.
• Test procedures and conditions to measure electrical conductivity/dissipative properties.
• Guidance on electrode type and conductive coating selection for proof testing.
• Application limits (new belts; use in explosive or fire-risk environments).
• Provisions for production-control testing (sampling vs. 100% testing left to national rules or agreement).

Typical use and users

Primary users are manufacturers of synchronous (timing) belts, quality-control and test laboratories, safety and reliability engineers in industries using belt drives (e.g., petrochemical, grain handling, printing, pharmaceuticals), procurement/specification engineers, and regulatory or certification bodies assessing equipment for explosive-atmosphere use.

Related standards

ISO 9563:2015 replaces and updates the earlier ISO 9563:1990. It is published under the work of ISO/TC 41 (belt drives and their components) and sits alongside other ISO standards covering belt types, pulleys and test methods for belt performance and uniformity. Users should consider complementary ISO standards for belt dimensions, profiles and mechanical testing when specifying belts for safety-critical applications.

FAQ

Q: What is this standard?

A: ISO 9563:2015 is an International Standard that defines electrical resistance limits and test methods for antistatic endless and open-ended synchronous (timing) belts to ensure they can dissipate static charges.

Q: What does it cover?

A: It covers characteristics and a test method for measuring electrical conductivity (dissipative properties), guidance on electrodes and conductive coatings for testing, and production-control testing considerations. It is aimed at new belts intended for use where static-charge dissipation is required.

Q: Who typically uses it?

A: Belt manufacturers, test laboratories, safety engineers, purchasers and compliance bodies in industries where electrostatic discharge could create a hazard (for example in explosive atmospheres). Manufacturers use it for product specification and quality control.

Q: Is it current or superseded?

A: ISO 9563:2015 is the current edition (second edition) published 14 September 2015; it replaced ISO 9563:1990 and has been through ISO's systematic review/confirmation process. Users should check for any later revisions or amendments before quoting the standard for new projects.

Q: Is it part of a series?

A: It is part of the ISO work programme for belt drives (ISO/TC 41) and complements other ISO standards on belt profiles, dimensions, mechanical properties and test methods for belt drives and their components.
