This standard 24/30491485 DC BS EN 13206 Plastics - Thermoplastic covering films for use in agriculture and horticulture is classified in these ICS categories:

• 65.040.30 Greenhouses and other installations
• 83.140.10 Films and sheets

This document 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 document. This specifies a classification for the durability of covering films and the test methods referred to in this document. This document specifies also test methods for the determination of the chlorine and sulfur contents of films subjected to use. This document 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 document 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. NOTE These rules allow estimating the residual value of the films. These provisions only apply to the 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.
