Overview

EN 60371-3-3:1995 (adopted as SIST EN 60371-3-3:1998) is a European specification for rigid mica materials used in electrical heating equipment. Aligned with IEC 60371-3-3:1983, the standard defines requirements for several types of insulating materials produced from mica splittings or mica paper, focusing on materials intended to provide reliable electrical insulation and mechanical support in heating devices.

Key topics

The standard addresses the essential aspects suppliers, manufacturers and designers need to control for rigid mica insulating materials. Main technical topics include:

• Material types and composition - classification of rigid mica products produced from mica splittings or mica paper.
• Functional requirements - performance characteristics required for use in electrical heating equipment (mechanical integrity, suitability for insulation under heating conditions).
• Dimensional and manufacturing tolerances - specification of acceptable sizes, thicknesses and product uniformity for rigid mica sheets and laminates.
• Quality and conformity - requirements for batch identification, marking and documentation to demonstrate compliance.
• Scope of application - definition of intended use cases within electrical heating equipment and limits of applicability.

Note: EN 60371-3-3 is a specification standard; it sets out the required characteristics and acceptance criteria rather than prescribing detailed design methods.

Applications

This standard is directly relevant for:

• Manufacturers of rigid mica insulating materials (mica sheets, laminates) who need to certify product conformity for heating equipment markets.
• Designers and OEMs of electrical heating equipment (e.g., industrial heaters, domestic appliances, heating elements) selecting insulation materials that must withstand thermal stress while providing electrical isolation.
• Testing and quality assurance laboratories that verify material compliance with European/IEC specifications.
• Compliance officers and procurement teams seeking standardized material specifications for contracts and product declarations.

Using EN 60371-3-3 helps ensure consistent material performance, interchangeability of supply and compliance with recognized international practice for mica-based insulation in heating applications.
