本标准规定了通过测定密闭呼吸计中需氧量或测定释放的二氧化碳量的方法,测定土壤中塑料材料最终需氧生物分解能力。本标准通过调整试验土壤的湿度以获得生物分解率的最佳程度。
本标准适用于以下材料:
----天然和(或)合成聚合物、共聚物或它们的混合物;
----含有如增塑剂、颜料或其他化合物等添加剂的塑料材料;
----水溶性聚合物;
----在试验条件下,不会对土壤中的微生物的活性产生抑制作用的材料,抑制作用可应用抑制控制或其他适当方法来测得。如果试验材料对土壤中的微生物的活性有抑制作用时,可采用较低浓度的试验材料、其他接种物或已预曝置的土壤。
本标准等同采用ISO 17556:2003《土壤中塑料材料最终需氧生物分解能力的测定 通过测定密闭呼吸计中需氧量或测定释放的二氧化碳的方法》(英文版),技术性内容完全相同,仅作如下编辑性修改:
———“本国际标准”一词改为“本标准”;
———用小数点“.”代替作为小数点的逗号“,”;
———删除了国际标准前言。
