Overview

EN 60674-3-3:1998 (CLC) specifies requirements for polycarbonate (PC) films used for electrical insulation. Aligned with IEC 60674-3-3:1992, this sheet of the EN 60674 series defines material classification and the essential performance characteristics required for PC films used in electrical and electronic applications. The standard covers three material types:

• Type 1: General purpose, amorphous, unstretched
• Type 2: General purpose, amorphous, stretched
• Type 3: For capacitor dielectrics, partially crystalline and stretched

This standard is intended to ensure consistent quality, safe electrical behavior and reliable performance of PC insulating films.

Key Topics and Requirements

EN 60674-3-3 addresses the following technical topics (as defined by the standard for PC films):

• Material classification by type (1–3) and intended electrical use
• Electrical performance criteria relevant to insulation and dielectric function (e.g., suitability as capacitor dielectric for Type 3)
• Mechanical and dimensional properties, including film thickness and tolerances, stretch condition (stretched/unstretched) and physical integrity
• Thermal behaviour and stability under expected service conditions
• Surface condition and appearance, to ensure proper processing and electrical safety
• Testing and conformity procedures to verify that manufactured films meet the specified requirements

Note: EN 60674-3-3 defines the scope and categories of tests and acceptance criteria for polycarbonate films rather than prescribing application-specific design values.

Applications and Who Uses It

This standard is relevant for:

• Manufacturers of polycarbonate insulating films and film suppliers seeking to certify product conformity
• Capacitor manufacturers selecting dielectric films (especially Type 3 materials)
• Electrical and electronic component designers specifying insulating materials for motors, transformers, coil windings, flexible substrates and other insulation layers
• Quality control and testing laboratories performing acceptance testing and type approvals
• Procurement, compliance and regulatory teams requiring documented material specifications for safety and interoperability

Using EN 60674-3-3 helps ensure consistent material selection, reliable dielectric performance and traceable quality for electrical insulation applications.
