UNDERGROUND AND PLASTIC FITTINGSSYSTEMS FLEXIBLE PLIABLE AND PLAIN SELF-RECOVERING CONDUITS AND FITTING SYSTEMS

FIELD OF APPLICATION FIELD OF APPLICATION
Underground conduit systems and metallic and non-metallic conduit fittings, assem-bled, threaded and non. Conduit systems and fittingsConduit systems and pliable metallic fittings and non, assembled, threaded and non MARKINGS CLASSIFICATIONS
Heavy-duty conduit: Trade mark; Product identification mark; L (light); N (normal) Markings: between 1 and 3m Fittings: Trade mark; Product identification mark; L; N Composed of 12 figures MARKINGS AND DOCUMENTATION
Conduit: Trade mark; Product identification Conduit may be also marked with classification code of at least 4 figures. Conduit markings: Spacing pref. at intervals of 1m but not greater than 3m; each spacing marked at least once Fittings: Code of at least 4 figs; or labelling on product or packaging Manufacturer must specify min. inner diameter of system DIMENSIONS

Water temp.: 23 ±2°C Salt water (lg/l) Insulation: water temp.: 23 ±2°C Fittings: According to manufacturer’s instructions With the receipt of New Approach Directives, the products which apply within their fieldof application must be manufactured in conformity with the relevant and essential requi- rements that must be met to be put in the market and in service across the European Community.A presumption of conformity to European New Approach Directives is the affixing of theCE Marking on the product and/or on its instruction manual and/or on the packaging.The Directives that can be applied to TUBIFOR products are the following: Dir. 72/23/CEEreceipt with the Rule Nr. 791 dtd. 18/10/1977 and amended by the Dir. 93/68/CEE related to the relevant safety standards of electrical material included in the Low Voltage Directive.The CE Marking must be applied since01/01/1996 according to Dir. EMC (89/399/CEE and 93/68/CEE);01/01/1997 according to Dir. LVD (73/23/CEE and 93/68/CEE);TUBIFOR products which apply to Directives bear the CE Marking since the above indica-ted dates.
