The IEC 60587:2022 standard specifies the methods for testing the resistance of polymer and other insulating materials to tracking and erosion under conditions of high voltage stress, contamination, and humidity. The test evaluates the material’s ability to withstand surface degradation caused by electrical arcing paths, which can compromise insulation integrity and safety in electrical systems.

Scope:

This standard applies to a wide range of polymer, composite, and other insulating materials used in electrical and electronic applications, including insulators, cable accessories, and other components prone to surface tracking. It aims to determine the material’s resistance to surface deterioration due to electrical tracking and erosion under specified test conditions, simulating operational environments, especially in polluted or moist conditions.

Conductor Types:

• Copper conductors
• Aluminum conductors
• Other metallic conductors used in insulation systems

Temperature Limit:

The maximum surface temperature during testing is typically controlled and specified based on the material’s rated temperature and application conditions.

Generally, the test is conducted at temperatures up to 70°C or as specified in the material datasheet or application standards.

Elevated temperature conditions can accelerate the aging and degradation processes for certain materials.

Tests and Requirements:

The testing involves the following key elements:

• Surface Contamination: Application of standardized pollution, salt fog, or other contaminants to simulate real environmental conditions.
• Voltage Application: Application of AC or DC voltage with varying levels depending on the standard’s specifications.
• Tracking and Erosion Observation: Monitoring for the formation of tracking paths, surface carbonization, erosion, or material degradation.
• Sample Evaluation: After testing, samples are inspected for:
• Development of carbonized tracks
• Material erosion or removal
• Surface degradation affecting insulation properties
• Acceptance Criteria: The sample passes if no significant tracking or erosion occurs beyond specified limits.

Significant Changes (from previous editions or related standards):

• Clarification of test durations and voltage levels for different material classes.
• Introduction of more precise environmental simulation conditions, including humidity and pollution levels.
• Updated procedures for surface preparation and insulation resistance measurement post-test.
• Enhanced documentation and criteria for evaluating erosion and tracking severity.
