Overview

SIST EN 60371-3-9:1998/A1:2007 is a European standard issued by CLC (European Committee for Electrotechnical Standardization) that specifies the requirements for moulding micanite, an insulating material based on mica. This amendment (A1:2007) updates the original 1995 version in alignment with IEC 60371-3-9:1995/A1:2007 and establishes harmonized specifications for moulding micanite used in electrical insulation applications. The standard is a part of the broader IEC 60371 series, which covers various insulating materials based on mica and their specifications, testing methods, and definitions.

Key Topics

• Material Definition
  Moulding micanite is a mica-based insulating material manufactured for electrical devices requiring robust and reliable insulation.

• Scope of Application
  The standard governs the composition, physical properties, and performance criteria of moulding micanite to ensure safety and functional consistency in electrical equipment.

• Raw Materials Requirements
  The mica splittings used must comply with IEC 60371-2 to ensure quality and consistency in insulation performance.

• Composition and Tolerances
  Products must meet specific composition limits verified by standardized testing methods in IEC 60371-2, guaranteeing reliable material properties.

• Physical Properties
  Thickness and other dimensional requirements are measured per procedures defined in IEC 60371-2, with strict tolerances to maintain uniformity.

• Performance Testing

  • Thermal Endurance: The material's ability to withstand elevated temperatures is tested according to Clause 21 of IEC 60371-2, ensuring durability under operational heat stress.
  • Electrical Strength: Tested using power frequency methods described in IEC 60243-1 and IEC 60371-2, moulding micanite must meet minimum electrical breakdown strength criteria to ensure safety and performance.

• Safety and Compliance
  Users are reminded to apply testing methods safely, emphasizing the responsibility to follow all safety guidelines when handling insulating materials.

Applications

SIST EN 60371-3-9:1998/A1:2007 applies primarily to the manufacture and quality assurance of moulding micanite used in electrical insulation systems. Typical applications include:

• High voltage electrical equipment
• Transformers and inductors
• Electrical motors
• Capacitors and other electrical components requiring mica-based insulating materials

The standard ensures these materials offer consistent thermal, mechanical, and electrical properties critical for reliable operation and safety in electrical engineering.

Related Standards

This amendment and standard form part of a cohesive framework of mica-based insulating material specifications, closely related to:

• EN 60371-1: Definitions and General Requirements for Mica-Based Insulating Materials
• EN 60371-2: Test Methods for Mica-Based Insulating Materials
• EN 60371-3-2: Specifications for Mica Paper (Sheet 2)
• IEC 60243-1: Test Methods for Electrical Strength of Insulating Materials at Power Frequencies
• IEC 60554-3-2: Specifications for Cellulosic Papers for Electrical Purposes
• IEC 60674-3-2: Specifications for Plastic Films Used in Electrical Insulation

These interconnected standards enable manufacturers and users to apply consistent quality and testing procedures across diverse insulating components based on mica.
