What international certifications and testing standards should a glass facade comply with?

Owners and specifiers should require recognized test evidence to verify performance. Core structural and air/water tests include ASTM E330 (structural), ASTM E283 (air infiltration), ASTM E331/E547 (water penetration), and EN equivalents where applicable. Cyclonic or impact regions require ASTM E1886/E1996 missile impact and cyclic pressure testing. Curtain wall systems often reference EN 13830 for system performance and ISO methods for thermal (U-value) and acoustic testing (ISO 140/717). Fire-related performance and reaction to fire are covered by NFPA, EN 13501 and local fire authority standards; glazed fire assemblies must be tested to maintain compartmentation. For Gulf projects, demonstrate compliance with local authority requirements (municipal approvals, SASO where applicable) and provide third-party factory audit records and material traceability. Central Asian projects may require harmonized technical documentation and national approvals; include certified test dossiers for customs and permitting. For metal curtain wall suppliers, produce a performance pack with test certificates, witness reports, QA records and material certificates so procurement teams can validate claims and expedite approvals.
