For test methods concerning the \u003cbr\u003ebiodegradability of plastic materials under mesophilic conditions, reference may be \u003cbr\u003emade to relevant standards such as ISO 23517 and ISO 22403. The method described \u003cbr\u003ein this document may be used to determine DT50 only when the plastic material has \u003cbr\u003ebeen demonstrated to be inherently biodegradable using appropriate standards (such as \u003cbr\u003eISO 23517 and ISO 22403). Furthermore, for plastic materials whose ultimate \u003cbr\u003ebiodegradability has not yet been established, the determined specific biodegradation \u003cbr\u003erate shall not be regarded as an intrinsic property of the material as a whole. \u003cbr\u003eThis document considers only the release of CO2 as a direct measure of the \u003cbr\u003emineralization of the test sample. \u003cbr\u003eThe method described in this paper can also be applied to solid reference materials. \u003cbr\u003eThis document does not apply to claims regarding \"marine, soil, and freshwater \u003cbr\u003ebiodegradation\" for biodegradable plastic materials. For such claims, please refer to the \u003cbr\u003erelevant product standards (if available). \u003cbr\u003eNOTE 2: Although results may indicate that the tested plastic materials and polymers will undergo \u003cbr\u003ebiodegradation at specific aerobic biodegradation rates or DT50 values under the prescribed test \u003cbr\u003econditions, such laboratory results cannot be directly applied to actual end-use sites or \u003cbr\u003eenvironmental areas affected by leakage, such as soil, marine environments, or lakes. \u003cbr\u003e\u003cbr\u003e\u003ch2\u003eBasic Data\u003c\/h2\u003e\u003ctable id=\"TableTabAbout0\" rules=\"all\" border=\"1\" style=\"font-family:Arial;font-size:Small;\"\u003e  \u003ctr id=\"TableTabRow10\"\u003e     \u003ctd id=\"TableTabCell110\" align=\"center\" font=\"bold\"\u003e \u003cb\u003eStandard ID\u003c\/b\u003e \u003c\/td\u003e    \u003ctd id=\"TableTabCell120\" align=\"center\"\u003e GB\/T 47330-2026 (GB\/T47330-2026)\u003c\/td\u003e  \u003c\/tr\u003e\n\u003ctr id=\"TableTabRow20\"\u003e     \u003ctd id=\"TableTabCell210\" align=\"center\" font=\"bold\"\u003e \u003cb\u003eDescription (Translated English)\u003c\/b\u003e \u003c\/td\u003e    \u003ctd id=\"TableTabCell220\" align=\"center\"\u003e Plastics - Determination of specific aerobic biodegradation rate of solid plastic materials and disappearance time (DT50) under mesophilic laboratory test conditions\u003c\/td\u003e  \u003c\/tr\u003e\n\u003ctr id=\"TableTabRow30\"\u003e     \u003ctd id=\"TableTabCell310\" align=\"center\" font=\"bold\"\u003e \u003cb\u003eSector \/ Industry\u003c\/b\u003e \u003c\/td\u003e    \u003ctd id=\"TableTabCell320\" align=\"center\"\u003e National Standard (Recommended)\u003c\/td\u003e  \u003c\/tr\u003e\n\u003ctr id=\"TableTabRow40\"\u003e     \u003ctd id=\"TableTabCell410\" align=\"center\" font=\"bold\"\u003e \u003cb\u003eClassification of Chinese Standard\u003c\/b\u003e \u003c\/td\u003e    \u003ctd id=\"TableTabCell420\" align=\"center\"\u003e G31\u003c\/td\u003e  \u003c\/tr\u003e\n\u003ctr id=\"TableTabRow50\"\u003e     \u003ctd id=\"TableTabCell510\" align=\"center\" font=\"bold\"\u003e \u003cb\u003eClassification of International Standard\u003c\/b\u003e \u003c\/td\u003e    \u003ctd id=\"TableTabCell520\" align=\"center\"\u003e 83.080.01\u003c\/td\u003e  \u003c\/tr\u003e\n\u003ctr id=\"TableTabRow60\"\u003e     \u003ctd id=\"TableTabCell610\" align=\"center\" font=\"bold\"\u003e \u003cb\u003eWord Count Estimation\u003c\/b\u003e \u003c\/td\u003e    \u003ctd id=\"TableTabCell620\" align=\"center\"\u003e 10,129\u003c\/td\u003e  \u003c\/tr\u003e\n\u003ctr id=\"TableTabRow70\"\u003e     \u003ctd id=\"TableTabCell710\" align=\"center\" font=\"bold\"\u003e \u003cb\u003eDate of Issue\u003c\/b\u003e \u003c\/td\u003e    \u003ctd id=\"TableTabCell720\" align=\"center\"\u003e 2026-03-31\u003c\/td\u003e  \u003c\/tr\u003e\n\u003ctr id=\"TableTabRow80\"\u003e     \u003ctd id=\"TableTabCell810\" align=\"center\" font=\"bold\"\u003e \u003cb\u003eDate of Implementation\u003c\/b\u003e \u003c\/td\u003e    \u003ctd id=\"TableTabCell820\" align=\"center\"\u003e 2026-10-01\u003c\/td\u003e  \u003c\/tr\u003e\n\u003ctr id=\"TableTabRow90\"\u003e     \u003ctd id=\"TableTabCell910\" align=\"center\" font=\"bold\"\u003e \u003cb\u003eIssuing agency(ies)\u003c\/b\u003e \u003c\/td\u003e    \u003ctd id=\"TableTabCell920\" align=\"center\"\u003e State Administration for Market Regulation, China National Standardization Administration\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cbr\u003e\u003cbr\u003e","brand":"www.ChineseStandard.us -- Field Test Asia Pte.
