en13432 certification是什么认证

材料（产品）的可堆肥性认证，换句话说是产品的生物可降解性认证。就是将产品在一定条件下埋入一定（专业）的肥料中，肥料经过特殊选种或培养，里面含有各种菌类。由于材料在水分，湿度，热量以及菌类的作用下分子链断裂发生降解，产物为二氧化碳等小分子。通过检测二氧化碳的释放量来鉴定材料的降解程度。这是目前最权威的标准。另外还有一个美国标准为ASTM6400，你可以自己查询下。
附上简单说明：
What does this EU standard EN13432 mean?
Today, the terms biodegradation, biodegradable materials, compostability etc.
are very common, but frequently misused! Consequently, this is a source of
misunderstanding. The European Standard EN13432 "Requirements for resins
recoverable through composting and biodegradation - Testing scheme and
evaluation criteria for the final acceptance of biological resins", resolves
this problem by defining the characteristics that a material must have, in order
to be defined as "compostable" or “biodegradable”. This norm is a reference
point for material manufacturers, public authorities, composters and also very
useful to consumers.
