IEC 61249-2-4:2001

IEC 61249-2-4:2001 defines requirements for reinforced base materials used in printed boards and other interconnecting structures, specifically polyester non-woven/woven fibreglass laminated sheet of defined flammability with copper cladding. It is relevant when engineering teams, procurement staff, or compliance reviewers need a technical reference for material selection and documented evaluation. By linking material construction, flammability behavior, and copper-clad form, IEC 61249-2-4:2001 supports technical review, verification activities, and procurement alignment for board-related manufacturing workflows.

IEC 61249-2-4:2001 standard overview

This document is part of the IEC 61249 series and focuses on reinforced base materials for printed boards and related interconnecting structures. Its scope, as indicated by the title, is centered on a polyester non-woven/woven fibreglass laminated sheet with defined flammability characteristics in a copper-clad form. For organizations handling engineering documentation or conformity assessment, it can serve as a compliance reference for material classification, product evaluation, and technical validation during design and sourcing reviews.

Applications of IEC 61249-2-4:2001

IEC 61249-2-4:2001 is commonly relevant to printed board fabrication, laminate procurement, and laboratory evaluation of copper-clad base materials used in electronic assemblies. It may be used in quality workflows where material consistency, flammability-related checks, and documented product assessment are part of approval or incoming inspection processes. The document is also useful for suppliers and manufacturers preparing technical documentation for board materials intended for controlled production and compliance-oriented engineering review.

Why IEC 61249-2-4:2001 matters

For teams responsible for technical compliance, the value of IEC 61249-2-4:2001 lies in providing a clear reference point for material identification and conformity assessment. It helps reduce risk in procurement and manufacturing by aligning expectations around the reinforced base material and its copper-clad construction. In testing workflows, it supports more consistent evaluation and documentation, which can improve operational consistency, quality assurance, and preparation for regulatory or customer-driven technical acceptance.

• Supports specification review for copper-clad reinforced base materials used in printed board applications
• Useful for procurement checks, supplier qualification, and material documentation control
• Helps laboratories and QA teams align testing workflows with a defined material reference
• Assists engineering and compliance teams with technical assessment and conformity assessment preparation
