欧盟标准 EN 12915-1 饮用水处理用产品.粒状活性碳粒径大180微米测试
Test item 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 Particle size greater than 180 microns
Test info 测试内容:
1. Particle size distribution |
According to EN12902-Products used for treatment of water intended for human consumption. |
Inorganic supporting and filtering materials. Methods of test |
2. Wettability |
Immersion of the product in boiling water.Cooling,sedimentation and filteration of the supernatant |
through a sieve to determine the quantity of material that is not wetted. |
3. Bulk density packed |
The bulk density packed of granular activated carbon is determined by measuring the volume packed |
by a free fall from a vibrating feeder into a 100ml graduated cylinder and weighing the known volume. |
4. Ball-pan hardness |
A screened and weighed sample of granular activated carbon is placed in a special hardness pan |
with a number of stainless steel balls,then subjected to a combined rotating and tapping action for 30 |
min. Degradation of particle size is determined by measuring the mass of granular activated carbon |
minimun particle size of the original sample. |
5. Water-soluble material |
According to EN12902-Products used for treatment of water intended for human consumption. |
Inorganic supporting and filtering materials.Methods of test |
6. Water-extractable substances |
According to EN12902-Products used for treatment of water intended for human consumption. |
Inorganic supporting and filtering materials.Methods of test |
7. Iodine |
According to EN12902-Products used for treatment of water intended human consumption. |
Inorganic suppotring and filtering materials.Methods of test |
