17、 the Secretariat of which is held by AFNOR. Within its programme of work, Technical Committee CEWC 334, Irrigation techniques, charged CEWC 3WG 1, Reel Machine Systems, to prepare the following standard: EN 12324-2, Irrigation techniques - Reel machine systems - Part 2: Specifications of polyethylen
18、e tubes for reel machines. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 2000, and conflicting national standards shall be withdrawn at the latest by February 2000. According to the CEN
19、ICENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden
20、, Switzerland and the United Kingdom.

OBSI 11-1999 Page 4 EN 12324-211 999 1 scope This European Standard specifies the characteristics that are requir
22、ed for the polyethylene (PE) tubes for irrigation reel machines. Those tubes are destined to be coiled onto structures of reel machines that conform to the size series specified in EN 12324-1, and to achieve the functions of carrying water and dragging the water emitting system, while it travels alo
23、ng the irrigated lane. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent
