Описание (английский):

This document specifies the maximum electrical resistance of a conveyor belt and the corresponding test method. The test is intended to ensure that the belt is sufficiently conductive to avoid the accumulation of electrical static charge which can be developed during service use. This document is not suitable or applicable to light conveyor belts as described in ISO 21183-1, the static electrical properties of which are measured by ISO 21178.

Overview

ISO 284:2025 is an international standard that specifies the electrical conductivity requirements and test methods for conveyor belts. The standard ensures conveyor belts are sufficiently conductive to prevent the buildup of static electrical charges during operation. This is critical for maintaining safety and performance in industrial environments where static discharge could cause hazards or equipment malfunction.

This standard applies specifically to conventional conveyor belts and excludes light conveyor belts, which are covered under ISO 21183-1 and tested according to ISO 21178. The document defines the maximum allowable electrical resistance and details a standardized test procedure to verify compliance.

Key Topics

Maximum Electrical Resistance: The conveyor belt’s electrical resistance must not exceed 3 × 10^8 ohms (300 MΩ), although lower resistance levels may be required for special applications.

Test Methodology: The test involves passing an electric current through a prepared test piece of the conveyor belt using specified electrodes and measuring resistance under controlled laboratory conditions.

Test Equipment: Includes insulated materials, cylindrical brass electrodes, ohmmeters, a direct current source (up to 1,000 V), and a contact agent to ensure good electrode-to-belt interface.

Test Piece Preparation: Test samples must be square, at least 300 mm per side, cut from the full belt thickness, and properly cleaned and conditioned.

Conditioning Atmosphere: Testing is performed after conditioning test pieces in a controlled atmosphere (preferably 23 °C ± 2 °C and 50 % ± 5 % relative humidity) as defined by ISO 18573.

Reporting Requirements: Detailed test reports must include belt material designation, test conditions, voltage applied, resistance values, and any deviations from the standardized test.

Applications

ISO 284:2025 is essential for industries relying on conveyor belt systems where static electricity buildup poses a risk, including:

Mining and mineral processing: Preventing static discharge in dusty or explosive environments.

Manufacturing and assembly lines: Ensuring smooth electrical dissipation for safety and operational reliability.

Food and pharmaceutical industries: Maintaining cleanliness and reducing electrostatic attraction of contaminants.

Logistics and packaging: Avoiding sparks that could damage sensitive goods or equipment.

Automotive and heavy industry: Protecting electronic components from electrostatic interference.

By adhering to ISO 284:2025, companies can reduce downtime, enhance worker safety, and comply with regulatory requirements for electrostatic safety in conveyor belt applications.

Related Standards

ISO 21183-1: Specifies characteristics and applications of light conveyor belts.

ISO 21178: Defines test methods for the static electrical properties of light conveyor belts.

ISO 18573: Covers test atmospheres and conditioning periods for conveyor belt testing.

ISO 282: Provides sampling methods for conveyor belts.

IEC 60250: Details permittivity and dielectric dissipation factor testing for insulating materials, relevant to understanding static charge behaviors on conveyor belts.

Adopting ISO 284:2025 supports effective static charge control in conveyor belts, promoting safe and reliable industrial operations. For comprehensive testing and specification compliance, manufacturers and users should refer directly to the full standard and associated documents.
