British Standards Institution

Sector: Manufacturing

Overview: Under the direction of the Standards Policy and Strategy Committee, is responsible for all UK Standardization work related to international and European proposals for Standards on Aerospace Hydraulic Systems. This committee shadows the work of ISO/TC 20/SC 10 carrying out appraisals of all documents issued by ISO/TC 20 SC 10 and CEN/ASD/STAN and preparing UK responses; determination of UK position on international proposals, appointment and briefing of UK delegates to ISO/TC 20/SC 10 meetings.
