Overview - ISO 27996:2024 (Aerospace fluid systems - Elastomer seals - Storage and shelf life)

ISO 27996:2024 defines requirements for packaging, storage and data recording of elastomeric seals and seal assemblies used in aerospace fluid systems prior to their installation into hardware. The standard covers how manufacturers and suppliers should protect elastomeric (vulcanized) parts from environmental degradation, maintain product identity, and record cure and batch information. It does not set limits for assembled components or their in-service life.
