en13432 certification是什么认证

是可降解材料测试和认证。

可堆肥材料认证则是指由权威的第三方经过一定的测试和认证程序，独立证明某种材料的可堆肥性能，材料堆肥性能，即是指测试堆肥条件下，材料具备如下性能：生物降解能力、崩解能力、重金属含量、堆肥产品对植物毒性。

扩展资料

根据引起降解的客观条件或机理，降解塑料大致可分为：生物降解塑料、光降解塑料、氧化降解塑料和水解降解塑料等。

它们之间又可以相互组合成性能更好的降解塑料，如：光/生物降解塑料等。 

环境降解塑料：曝露于环境条件下，如光、热、水、氧、污染物质、微生物、昆虫以及风、砂、雨等及机械力等联合作用而发生降解的塑料，是降解塑料的总称。

生物可降解塑料：可以由自然界存在的微生物而引起降解的塑料，这些微生物包括细菌、真菌和藻类生物。

可堆肥塑料：在堆肥过程中塑料经过生物降解过程释放出CO2、水、无机化合物和生物量的比率符合可堆肥材料的要求，并且塑料降解后不可见、不可区分以及无毒性残留。

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.

According to the European Standard EN13432, a compostable material must have
the following characteristics:

1. Biodegradability, which is determined by measuring the actual metabolic
conversion of the compostable material into carbon dioxide. This property is
quantitatively measured using the standard test method, EN14046 (which is also
published as ISO 14855: biodegradability under controlled composting
conditions). The acceptance level is 90%, which must be reached in less than 6
months.

2. Disintegrability, that is, the fragmentation and loss of
visibility in the final compost (absence of visual contamination). This is
measured with a composting test (EN14045). The test material is degraded,
together with organic waste, for 3 months. After this time, the compost is
sieved with a 2 mm sieve. The residues of test material with dimensions higher
than 2 mm are considered as not having disintegrated. This fraction must be less
than 10% of the initial mass.

3. Absence of negative effects on the
composting process. This is checked with a composting test.

4. Low
levels of heavy metals (below the predefined maximum values), and absence of
negative effects on the quality of the compost (e.g. reduction of the agronomic
value and presence of eco-toxicological effects on the growth of plants). A
plant growth test (OECD test 208, modified) is carried out on compost samples
where the degradation of the test material has taken place. There must be no
difference from control compost. Other chemical-physical parameters that must
not be different from those of the control compost after the degradation are the
pH, salinity, volatile solids, N, P, Mg, K.

可降解材料的认证，对应的证书为欧洲小幼苗和DIN证书，是检测一家公司提供的产品是否符合生物降解属性的认证。

严格来说，没有EN 13432 certification这种认证，因为EN 1432是标准，如果实验室有此份标准的检测能力，仅能出具检测报告；而认证一般是依据相应的检测标准，检测合格后，发证机构依据认证要求，对产品产品评估，当然包括对测试报告的评估，符合认证要求后，允许申请方在其产品加加贴相应的认证标志，如生物可降解方面的BPI认证&DIN Certco认证&OK Compost认证。
