TS EN 60763-1

TS EN 60763-1 is the foundational part of the laminated pressboard series for electrical purposes, providing the definitions, material classification, and general requirements that apply across the whole standard set. It establishes the common technical language used to identify laminated pressboard materials and the main material types into which they are divided, so that later parts of the series can be read consistently.

Why terminology and classification matter

Laminated pressboard is a cellulose-based insulating material built up into a structured form for electrical applications. In this field, definitions and classification are not merely vocabulary aids; they determine how material families are distinguished by construction, intended use, and expected behavior. The terminology in this part supports a coherent interpretation of the more detailed requirements that appear elsewhere in IEC 60763.

General technical context

Paper-based laminated insulation materials are widely used where electrical insulation must be combined with mechanical strength, such as in transformers and rotating electrical machinery. Classification does not itself prove suitability for a particular design, but it gives a stable framework for discussing material types across manufacturers and applications. That makes this part especially useful as a reference for consistent specification and communication in the electrical insulation domain.

• Provides the core definitions used throughout the IEC 60763 series.
• Organises the material into defined types.
• Sets out general requirements applicable to all covered material.
• Standardises terminology for laminated pressboard used in electrical applications.
