About This Item
IEC 61249-2-22:2005 defines requirements for reinforced base materials used in printed boards and other interconnecting structures, specifically modified non-halogenated epoxide woven E-glass laminated sheets with defined flammability performance in a vertical burning test, including copper-clad forms. For engineering teams and procurement specialists, it serves as a focused technical reference when evaluating laminate material suitability, documenting product requirements, and supporting conformity assessment. As a primary reference in the IEC 61249 series, IEC 61249-2-22:2005 helps align material selection, test evidence, and supplier documentation with a clearly defined material specification.
Purpose of IEC 61249-2-22:2005
The purpose of IEC 61249-2-22:2005 is to establish a recognized technical basis for a particular class of reinforced laminate materials used in printed board applications. Its scope is centered on material definition and flammability-related performance for modified non-halogenated epoxide woven E-glass laminated sheets, with copper-clad variants included in the title. In practice, it is relevant where technical review, product evaluation, and documented evaluation of base materials are needed to support compliance, procurement decisions, and engineering validation.
Compliance applications of IEC 61249-2-22:2005
Organizations may use IEC 61249-2-22:2005 during supplier qualification, incoming material review, laboratory evaluation, and product documentation for printed boards or other interconnecting structures. It is particularly useful where material traceability, flammability classification, and consistent construction details matter in compliance workflows. The reference can support quality workflows and technical assessment for electronics manufacturing, materials sourcing, and verification activities involving copper-clad laminate materials intended for controlled, repeatable use in board fabrication.
Benefits of IEC 61249-2-22:2005
Using IEC 61249-2-22:2005 can improve consistency in specification writing, procurement review, and conformity assessment preparation by giving teams a common technical baseline for a defined laminate material family. It may reduce risk in engineering documentation by clarifying what material class is being referenced and how its key performance expectation is framed. For laboratories and compliance teams, it can also support more consistent testing workflows, easier comparison of supplier data, and more reliable technical validation across projects.
