Up-to-date lists and bibliographical references concerning such nationalstandards may be obtained on application to the Central Secretariat or to any CEN member.This European Standard exists in three official versions (English, French, German). A version in any other language made by translationunder the responsibility of a CEN member into its own language and notified to the Central Secretariat has the same status as the officialversions.CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia,Slovenia, Spain, Sweden, Switzerland and United Kingdom.EUROPEAN COMMITTEE FOR STANDARDIZATIONCOMITÉ EUROPÉEN DE NORMALISATIONEUROPÄISCHES KOMITEE FÜR NORMUNGManagement Centre: rue de Stassart, 36

As a consequence, vacuum is designated by a negative value 3.8 maximum allowable pressure PS maximum operating pressure for which the equipment is designed, as specified by the manufacturer. This is identical to the design pressure 3.9 maximum/minimum allowable temperature TS maximum/minimum temperature for which the equipment is designed, as specified by the manufacturer. The maximum allowable temperature is identical to the design temperature 3.10 lamina ply or layer of glass reinforced thermosetting resin 3.11 laminate composite structure consisting of one or more lamina 3.12 filament winding production technique for winding of continuous filaments of glass fibre with the specified resin system applied in a systematic manner and cured on a mandrel or other supporting structure 3.13 chemical resistant layer (CRL) protective layer in accordance with 4.3 of EN 13121-2:2003 3.14 thermoplastic lining (TPL) protective layer in accordance with 4.4 of EN 13121-2:2003 3.15 contact layer layer to increase adhesion between TPL and structural laminate 3.16 hoop winding winding for which the fibre direction is perpendicular to the rotation axis of the vessel
