本文件规定了一种试验方法，通过气相色谱法测量释放的二氧化碳量，测定在受控堆肥条件下加速水解后获得的纺织材料水解液的生物降解性。 本试验方法适用于由聚对苯二甲酸乙二醇酯琥珀酸酯、聚己内酯、碳酸聚丙烯酯、聚丁二酸丁烯酯或使用它们的共聚物制成的石油基人造可生物降解纺织材料。

This document specifies a test method for the determination of the biodegradability of the hydrolysate of textile materials obtained after accelerated hydrolysis under controlled composting conditions by measurement of the amount of evolved carbon dioxide with a gas chromatography. This test method can be applied to petroleum-based man-made biodegradable textile materials which are manufactured from polyethylene terephthalate succinate, polycaprolactone, polypropylene carbonate, polybuthylene succinate or copolymer using them.
