This European Standard specifies the requirements related to dimensional, mechanical, optical and thermal characteristics of thermoplastic 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 durability 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 horticulture in Europe, in the thickness range 20 µm up to more than 250 µm, 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 disposal 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.Cross References:ISO 4593ISO 527-1ISO 527-3EN 13031-1ISO 4892-1ISO 4592EN ISO 4892-1EN 16472EN ISO 527-1ISO 4892-3EN 10244-2EN ISO 527-3ISO 4591EN ISO 4892-3:2016ISO 7765-1:1988 (R09)EN ISO 7765-1:2004ASTM D1003 - 13ISO 4892-2:2013EN ISO 4892-2:2013ISO/TR 19032:2006ISO 10640:2011ISO 9370:2009ISO 15270EN 15344EN 15347EN 15343UNE 53087-2:2005Cepla Method MA-03:2013Cepla Method MA-02:2013Incorporates the following:Amendment, February 2020
