Full title and description

STB BS EN 60464-3-2:2002 (with Amendment A1:2006) — "Varnishes used for electrical insulation — Part 3: Specifications for individual materials — Sheet 2: Hot curing impregnating varnishes". This is the European/IEC specification that defines requirements for hot‑curing impregnating varnishes used as electrical insulating materials, including key property requirements at elevated temperatures and test/marking information.

Abstract

This standard specifies requirements and performance characteristics for hot‑curing impregnating varnishes used in electrical insulation systems (for example in windings, coils, transformers and similar applications). It sets material specifications, test conditions (including elevated temperature requirements), and conformity criteria to ensure safe electrical insulating performance when used in relevant electrical equipment.

Scope

This sheet of EN/IEC 60464 Part 3 specifies material requirements for hot‑curing impregnating varnishes used for electrical insulation. It covers composition‑related specification points and performance tests — in particular tests at elevated temperatures relevant to the service conditions of varnished impregnated windings and components — and lists the required test methods, limits and conformity information for material suppliers and test laboratories.

Key topics and requirements

• Definition and material classification of hot‑curing impregnating varnishes (scope and terminology).
• Specified physical and electrical properties to be met (including dielectric, thermal and mechanical characteristics at elevated temperatures).
• Required test methods and test conditions (temperatures, durations, test specimens).
• Marking, documentation and supplier conformity/declaration requirements for materials.
• Guidance on selection and limits for application in electrical equipment (e.g., windings, coils, transformers).

Typical use and users

Primary users are varnish manufacturers, material suppliers, test laboratories, and engineers in electrical equipment manufacturing (motors, transformers, coils, generators). The standard is used for material specification, quality control, product datasheets and type testing when impregnating varnishes are specified for electrical insulation applications.

Related standards

Related documents often referenced alongside EN/IEC 60464-3-2 include other parts of the IEC/EN 60464 series (Part 3 sheets for different varnish types), electrical insulation test standards such as EN/IEC test methods for thermal evaluation and dielectric strength (for example EN 60085, IEC test methods), and other material‑specification standards in the IEC 60000–60999 series that cover insulating materials and test procedures. Users should consult the national catalogue for exact cross‑references and amendments.
