Overview

EN 61628-2:1999 - Corrugated pressboard and presspaper for electrical purposes - Part 2: Methods of test (CLC) specifies the standardized test methods used to assess corrugated pressboard and presspaper that are classified under EN 61628-1. The standard defines how to determine corrugation geometry, dimensional stability on drying, and key mechanical properties relevant to electrical insulation performance.

Key topics

The standard focuses on test methods and measurable properties rather than material composition. Main technical topics include:

• Type and dimensions of corrugation - standardized identification and measurement of corrugation profile and geometry.
• Dimensional changes on drying - procedures to evaluate shrinkage/expansion when the material is dried under specified conditions.
• Compressive strength - methods to measure the load-bearing capacity of corrugated pressboard/presspaper under compression.
• Compression modulus - procedures to determine stiffness in compression (elastic response) for quality control and design input.
• Relationship to classification in EN 61628-1 - tests apply to materials as classified in Part 1.

Note: EN 61628-2 provides test procedures and acceptance criteria context, not manufacturing specifications.

Applications

EN 61628-2 is used wherever corrugated pressboard and presspaper serve as electrical insulating materials. Typical practical applications include:

• Design verification and quality control for insulating components and barriers in electrical equipment
• Material acceptance testing by manufacturers and purchasers
• Specifying test requirements in procurement documents for electrical insulation materials
• Supporting safety and reliability assessments for transformers, switchgear, coils, and other electrical apparatus where board/paper insulation is employed

(Use of the materials in specific equipment should be validated against device-specific and national regulations.)

Who uses this standard

• Manufacturers of corrugated pressboard and presspaper for electrical insulation
• Independent testing laboratories and quality assurance teams
• Design and development engineers in electrical equipment industries
• Procurement specialists specifying insulation material performance
• Certification and compliance bodies validating material test results

Related standards

• EN 61628-1 - Classification and general requirements for corrugated pressboard and presspaper (reference for material classes)
• Other international and regional standards on insulating papers and boards and general electrical insulation testing (e.g., related IEC/CENELEC documents) - consult national standardization bodies for cross-references.
