Anotation

Description / Abstract: 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 or non-dispersive infrared. 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.
