This standard is related to others that will be drawn up for each system component (techn
18、ical characteristics and test methods). 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of an identical text or by endorsement, at the latest by February 2002, and conflicting national standards shall be withdrawn at the latest by February 2002.

20、Spain, Sweden, Switzerland and the United Kingdom. 3 EN 13635:2001 (E) Introduction The growing use of localised irrigation systems in farming and gardening has drawn attention to the need for a model on which to base the characteristics of these systems. This document is intended to enhance underst
21、anding between localised irrigation users and facility assemblers. 4 EN 13635:2001 (E) 1 Scope This European Standard specifies the technical and functional characteristics that shall be indicated by manufacturers of localised irrigation systems for user information to aid them in their choice of fa
22、cilities and materials. This standard is related to others that will be drawn up for each system component (technical characteristics and test methods). This European standard defines localised irrigation systems, characterising the various components which comprise them. 2 Terms and definitions For
23、 the purposes of this European Standard, the following terms and definitions apply: 2.1 localized irrigation method of irrigation whereby plants are watered by small amounts of water at low pressure applied to the soil, below or at the ground surface, without wetting the entire soil surface. It embr
24、aces several methods such as drip and microsprinkler irrigation 2.1 .I drip irrigation the application of water as drips or tiny streams through outlets 2.1.2 microsprinkler irrigation method of irrigation whereby water is applied in the form of a spray, mist or stream 2.2 chemigation application of
