SIST EN 60893-2:2005

Overview

EN 60893-2:2004 (CLC) is the European standard that specifies methods of test for industrial rigid laminated sheets based on thermosetting resins used for electrical insulating purposes. It complements EN 60893-1 (Part 1), which defines the material types, grades and general requirements. EN 60893-2:2004 provides the standardized way to verify that electrical insulating laminates meet performance expectations for use in electrical and electronic equipment.

Key Topics

This part of the EN 60893 series focuses on practical, repeatable test procedures and typically covers test categories such as:

• Electrical tests (e.g., tests that assess dielectric performance and insulation properties)
• Mechanical tests (e.g., assessments of tensile strength, flexural properties and impact resistance)
• Thermal tests (e.g., evaluation of thermal stability, heat resistance and thermal ageing behaviour)
• Environmental and ageing tests (e.g., humidity, water absorption, and long‑term endurance)
• Dimensional and visual tests (e.g., thickness, flatness, surface appearance)
• Chemical and resistance tests (e.g., resistance to solvents or corrosive atmospheres)

Note: EN 60893-2 defines how tests should be performed and reported for the material classes identified in EN 60893-1; it does not redefine material classification itself.

Applications

EN 60893-2 is directly applicable to organizations involved with electrical insulating laminates and is used to:

• Verify batch quality in manufacturing of rigid laminated sheets for switchgear, transformers, motor components and other electrical assemblies
• Provide objective, comparable test results for procurement and specification in component and equipment supply chains
• Support type testing and routine quality control in independent test laboratories
• Aid design engineers in selecting laminates that meet required mechanical, electrical and thermal criteria

Typical users: laminate manufacturers, electrical component designers, test laboratories, quality managers, procurement specialists and certification bodies.

Related Standards

• EN 60893-1 - Material definitions and general requirements (Part 1)
• Relevant IEC/CENELEC documents and national standards for electrical insulating materials and test methods (refer to CLC catalogue for up‑to‑date cross‑references)

By using EN 60893-2 test methods, stakeholders ensure consistent, reproducible assessment of industrial rigid laminated sheets based on thermosetting resins, improving safety, interoperability and product reliability in electrical applications.
