This standard specifies a method for determination of the resistance of chemically-pretreated textiles
to the action of microorganisms present in soil in comparison with untreated textiles.
This method is applicable to flat textiles made of cellulosic-containing yarns (tentage, tarpaulins,
webbing and tapes) that will typically come into contact with soil during use.
Due to the inherent resistance of most synthetic fibres to attack by microorganisms, fabrics containing
a high proportion of synthetic fibres can only be judged by these methods for changes in structure and
appearance.
Although this method allows good reproducibility of results, it is intended to show comparative
performance rather than provide absolute values.
NOTE Heavy tarpaulin fabrics and webbing may be of such a structure that samples without finish are
resistant within a 14 days soil burial period. Also in such cases the decay rate of the untreated sample
determines the length of the burial period.
Diese ÖNORM beschreibt ein Verfahren zur Bestimmung der Widerstandsfähigkeit von Textilien, die einer chemischen Behandlung gegen die Einwirkung der im Boden vorhandenen Mikroorganismen unterzogen wurden. Das Verfahren ist auf textile Flächengebilde aus cellulosehaltigen Garnen (Zeltstoffe, Planen, Gurte und Bänder) anwendbar, die während des Gebrauchs typischerweise mit dem Boden in Berührung kommen.
