Testitem 测试名称: Virgin granular activated carbon饮用水处理用产品.粒状活性碳粒径大于180微米Particlesize greater than 180microns
Testinfo 测试内容:
1. Particlesize distribution |
According to EN12902-Productsused for treatment of water intended for humanconsumption. |
Inorganic supporting andfiltering materials. Methods of test |
2.Wettability |
Immersion of the product inboiling water.Cooling,sedimentation and filteration of thesupernatant |
through a sieve to determinethe of material that is not wetted. |
3. Bulkdensity packed |
The bulk density packed ofgranular activated carbon is determined by measuring the volumepacked |
by a free fall from a vibratingfeeder into a 100ml graduated cylinder and weighing the knownvolume. |
4. Ball-panhardness |
A screened and weighed sampleof granular activated carbon is placed in a special hardnesspan |
with a number of stainlesssteel balls,then subjected to a combined rotating and tappingaction for 30 |
min. Degradation of particlesize is determined by measuring the mass of granular activatedcarbon |
minimun particle size of theoriginal sample. |
5.Water-soluble material |
According to EN12902-Productsused for treatment of water intended for humanconsumption. |
Inorganic supporting andfiltering materials.Methods of test |
6.Water-extractable substances |
According to EN12902-Productsused for treatment of water intended for humanconsumption. |
