Performance of textile and non-woven materials against penetration and permeation of liquid pesticides
According to Regulation (EC) No. 1107/2009 on plant protection products (pesticides), when the conditions require the use of protective clothing, the effectiveness of this protection must be verified. The performance of protective clothing against penetration and permeation by pesticides was assessed according to ISO 22608:2004 and EN ISO 6529:2001, respectively. The penetration percentages for working coveralls, obtained on three replicates, varied widely and were highly dependent on the products and the dilutions. However, low penetration percentages were obtained for working coveralls that were treated with a water repellent. For coveralls that were certified according to Directive 89/686/EEC, the penetration percentages were low and depended on the products and the dilutions. For the certified coveralls (category III type 4 according to Directive 89/686/EEC), cumulative permeations were collected over a wide range and depended strongly on the products and dilutions. However, low cumulative permeations were obtained for the certified coveralls and gowns (category III type 3).
