the temperature (from 20 °C to 35 °C) for every film and every tested fumigant but without a highly significant difference. The most common temperature, 25 °C, is therefore considered to be acceptable and has been selected as the standard test temperature (see Conditions 1 and 2 in 5.2); e) the film permeability increases with the relative humidity (from 35 % to 100 %) for every film and every tested fumigants with highly significant differences particularly for VIFs.

¶ 10 «2 7.8 a Other light sources may be used provided that a correlation between the test results obtained with these light sources and these obtained after a natural exposure can be demonstrated. Details of these methods are given in Annex A (informative). In case of dispute, the exposure to xenon-arc lamps according to 7.5 shall be used. b For black coloured films, weather resistance corresponds to an exposure of one year after being installed in a climatic zone corresponding to a global solar radiant exposure of 4,2 GJ/m2/year to 5,4 GJ/m2/year (100 kLy/year to 130 kLy/year) (data from EN 13655 [2]). For films intended to be exposed during longer durations and/or in more severe conditions, the minimum duration of exposure to artificial weathering shall be defined by agreement between the manufacturer/supplier and the customer. c The peel strength may also be determined by a peel test according to EN ISO 2411 [3], subject to an agreement between the parties. The corresponding requirement shall also be defined by agreement between the parties. d Class 2 barrier films are generally supplied without folds. For barrier films to be joined together by gluing in situ, the method to assess bondability and the corresponding requirement shall be defined by agreement between the parties. SIST EN 17098-1:2018
