National foreword This document (EN 13206:2017) has been prepared by Technical Committee CEN/TC 249 “Plastics” (Secretariat: NBN, Belgium). The responsible

5、German body involved in its preparation was DIN-Normenausschuss Kunststoffe (DIN Standards Committee Plastics), Working Committee NA 054-04-10 AA “Thermoplastic films for use in agriculture”. For the International Standards referred to in this standard there are no national standards available. The

6、European Standards referred to in this document have been published as DIN EN or DIN EN ISO Standards with the same number. This European Standard specifies minimum requirements for thermoplastic tunnel and covering films in the agricultural sector, including their resistance to weathering (UV stabi

7、lity) which is tested in an accelerated laboratory test in a test apparatus with a filtered Xenon arc fading lamp test to simulate sunlight. Annex B of this standard describes an empirical correlation from a comparative study between natural exposure and artificial weathering and an accelerated labo

8、ratory test at an irradiance of 0,35 W/(m2nm) at 340 nm. For practical reasons, this standard also enables the testing of the UV resistance of the plastics in a Xenon arc test apparatus with an irradiance of 0,51 W/(m2nm) at 340 nm as is customary in other test standards, or with UV fluorescent tube

9、s or metal halide lamps as alternative light sources. The material degradation of polymers commonly induced by the UV portion of the radiation is a complex, multi-stage process, and each change of the testing scenario can influence the individual degradation stages to a varying degree or even change

10、 routes of degradation in general (see indications in DIN EN ISO 4892-1:2016-10, Clause 4 and Annex A). The comparative study is to be considered as material-specific and is not necessarily applicable to all types of film. The empirical correlation between the differentlight sources described in thi

11、s standard can thus not be considered as generally applicable. The change inthe irradiance or the use of different filter types to simulate solar radiation in Xenon devices can have an influence on the correlation as well as the use of alternative light sources and is ideally supported by an individ

12、ual assessment. Amendments This standard differs from DIN EN 13206:2001-07 as follows: a) normative references have been updated; b) a minimum thickness of the film has been specified; c) test methods have been updated accordingly; d) this revision also specifies test methods for the determination o

13、f the chlorine and sulphur contents of used films and defines guidelines for their installation, use and disposal; e) the classification according to the durability of the covering films has been extended to include an additional class; f) the standard has been editorially revised.

29、ean foreword This document (EN 13206:2017) has been prepared by Technical Committee CEN/TC 249 “Plastics”, the secretariat of which is held by NBN. This document supersedes EN 13206:2001. This European Standard shall be given the status of a national standard, either by publication of an identical t

30、ext or by endorsement, at the latest by July 2017, and conflicting national standards shall be withdrawn at the latest by July 2017. The following technical changes have been made in comparison to EN 13206:2001: a minimum thickness of the film is fixed; the test methods have been updated as appropri

31、ate; this revision specifies also test methods for the determination of the chlorine and sulfur contents of the films subjected to use and defines guidelines for installation, use and disposal; the classification for the durability of the covering films is extended to a further class. Attention is d

32、rawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the follo

33、wing countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, N

DIN EN 13206:2017-05 EN 13206:2017 (E) 51 Scope This European Standard specifies the requirements related to dimensional, mechanical, optical and thermal characteristics of thermo

35、plastic films used for covering permanent or temporary greenhouses and walking tunnels and low tunnels used for forcing and semi-forcing vegetable, fruit and flower crops. Lay-flat perforated cover films are also in the scope of this European Standard. It specifies a classification for the durabilit

36、y of covering films and the test methods referred to in this standard. This European Standard specifies also test methods for the determination of the chlorine and sulfur contents of films subjected to use. This European Standard is applicable to thermoplastic covering films used in agriculture and

37、horticulture in Europe, in the thickness range 20 m up to more than 250 m, based on polyethylene and/or ethylene copolymers materials, of the following types: non-thermal films, thermal clear films and thermal diffusing films. This European Standard also defines guidance for installation, use and di

38、sposal of covering films. It defines the conventional expected lifetime, as well as rules that allow evaluating the remaining use potential in the event of a failure before the normal end-of-use date. NOTE These rules allow estimating the residual value of the films. These provisions only apply to t

39、he film itself and the damage it has undergone. Any other problem falls within the scope of professional practices and the general terms and conditions of sale. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for
