DIN EN 4888:2025-05

This document specifies minimum reliability test requirements for sub-components of commercial aircraft passenger seats. Test procedures including in-service load cases regarding passenger behaviour for sub-seat components are defined. Abuse loads are excluded. This document is applicable to the subseat components such as but not limited to backrest, headrest, armrest, table, literature pocket and control elements. This document does not apply to belts, Inflight-Entertainment, seat dress cover and cushions. Additional environmental influences like temperature, radiation, gases and liquids may also alter the reliability of the aircraft passenger seats and their sub-components over their lifetime but are not taken into consideration of this document. Tests on abrasion and surface durability are defined in EN 4860, EN 4864 and EN 4876. The standard EN 4888 has been prepared by the ASD-STAN of the AeroSpace and Defence Industries Association of Europe (ASD) with the participation of German experts at DIN Standards Committee Aerospace (NL). The responsible German standardization committee is Working Committee NA 131-09-02 AA "Sitze, Inflight-Entertainment" ("Seats, inflight-entertainment") at DIN Standards Committee Aerospace (NL).
