Textiles - Determination of the resistance of cellulose-containing textiles to micro-organisms - Soil burial test - Part 2: Identification of long-term resistance of a rot retardant finish (ISO 11721:2003)

ISO 11721-2:2003 describes a test procedure for identification of the long-term resistance of a rot-retardant finish against the attack of microorganisms in the soil.
It permits a distinction to be made between rot-retardant finishes with no long-term resistance, with regular long-term resistance and with increased long-term resistance, in order to assess the suitability for use in the tropics.
As the soil burial test is a biological process and the test soil not accurately defined, ISO 11721-2:2003 only covers the comparison of finished and unfinished specimens.

L'ISO 11721-2:2003 décrit un mode opératoire d'essai permettant d'identifier la résistance à long terme d'un traitement d'imputrescibilité aux attaques des micro-organismes présents dans la terre.
Elle permet de distinguer les traitements d'imputrescibilité ayant une résistance à court terme, ceux ayant une résistance à long terme normale et ceux ayant une résistance à long terme accrue, afin d'évaluer leur aptitude à l'emploi sous les tropiques.
L'essai d'enfouissement étant un processus biologique et la terre utilisée pour l'essai n'étant pas définie avec précision, le contenu de l'ISO 11721-2:2003 constitue uniquement une comparaison entre des éprouvettes traitées et des éprouvettes non traitées.

Introduction

Cellulose containing textiles are considered as resistant against the attack of microorganisms living in

the soil, provided that their structure, appearance and maximum tensile strength have not been

altered essentially after a soil burial test.

The assessment of damage resistance takes into account the structure, the aspect and the changes

in the maximum tensile strength, compared to untreated specimens of the same material quality. It is

assessed by comparing the relative decrease of maximum tensile strength of buried specimens, with

that of unburied control specimens.

A long-term rot retardant finish or an increased long-term resistance meets with the requirements for

cellulose containing textiles if the maximum tensile strength of a buried specimen, compared with an

unburied specimen, does not decrease by more than 25 %.

The soil burial intervals for long-term retardant finishes take twice the time needed for control

specimens to lose 80 % of their maximum tensile strength. The soil burial intervals for increased long-

term resistant finishes takes four times the time needed for the controls to lose 80 % of their maximum

tensile strength.
