Overview

EN 60763-2:2007/A1:2023 is a vital European standard providing the Specification for laminated pressboard – Part 2: Methods of test. Developed and maintained by CLC in alignment with the International Electrotechnical Commission (IEC 60763-2:2007/AMD1:2023), this amendment updates testing methods for laminated pressboard materials used predominantly in electrical insulation. The standard ensures consistent and reliable evaluation of physical and mechanical properties critical for safety and performance in electrical applications.

This amendment, approved in December 2023 and mandatory for national adoption by September 2024, focuses on modernizing test procedures, including dimensional stability and moisture content assessments, which are essential for quality control in the manufacturing and utilization of laminated pressboard.

Key Topics

• Test Methods Specification
  EN 60763-2:2007/A1:2023 defines precise procedures for testing laminated pressboard properties, ensuring repeatable and accurate results across laboratories and production facilities.

• Shrinkage Measurement
  The updated test for shrinkage involves measuring the dimensional changes in length and thickness of the laminated pressboard after drying. This includes:

  • Conditioning test specimens under specified moisture content
  • Using calibrated calliper gauges and micrometers for dimensional measurements
  • Calculating shrinkage as a percentage difference before and after drying
  • Reporting directional shrinkage (machine and cross-machine direction) and thickness change

• Moisture Content Determination
  Accurate determination of moisture content is crucial for evaluating material stability and performance. The amendment specifies the calculation based on mass loss due to drying, contributing to assessing the pressboard's insulating quality.

• Test Specimen Preparation and Conditioning
  The standard outlines exact dimensions for test pieces and conditioning protocols to maintain consistency in sample handling prior to testing.

Applications

• Electrical Insulation Materials
  Laminated pressboard tested under this standard is widely used in transformers, switchgear, and other electrical equipment requiring reliable solid insulation, ensuring electrical safety and durability.

• Quality Control in Manufacturing
  Manufacturers of laminated pressboard rely on EN 60763-2:2007/A1:2023 to verify that products meet critical physical criteria, supporting compliance with international standards and customer specifications.

• Research and Development
  This standard supports innovation in insulating materials by providing a benchmark for evaluating new laminates or composites in electrotechnical applications.

• Regulatory Compliance
  By implementing the standardized test methods, companies ensure that their products conform to European and international electrotechnical regulations, facilitating market access.

Related Standards

• IEC 60763 Series
  EN 60763-2:2007/A1:2023 is part of the broader IEC 60763 series covering the overall specifications for laminated pressboard, including general requirements (Part 1) and other test methods.

• ISO/IEC Directives
  The development and maintenance of this standard follow ISO/IEC guidelines to ensure international harmonization and technical rigor.

• IEC 60085 – Electrical Insulation
  Complements testing of insulating materials, providing overarching safety and performance criteria.

• EN/IEC 60216 – Thermal Endurance of Electrical Insulating Materials
  Relevant when combined with laminated pressboard testing to assess long-term stability under thermal stress.
