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:

Applicable to polymer, composite, and other insulating materials used in electrical and electronic components, such as insulators and cable accessories. The test simulates harsh operational environments, including pollution and moisture, to assess surface degradation resistance.

Conductor Types:

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

Temperature Limit:

• The test temperature is generally up to 70°C, adjustable based on material specifications and application requirements.
• Elevated temperatures may accelerate aging and degradation in testing.

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 :

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.
