Testitem 測試名稱: Virgin granar activated carbon飲用水處理用產(chǎn)品.粒狀活性碳粒徑大于180微米Particlesize greater than 180microns
Testinfo 測試內(nèi)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 thesupernatantthrough a sieve to determinethe of material that is not wetted. 3. Bkdensity packed The bk density packed of granaractivated carbon is determined by measuring the volumepackedby a free fall from a vibratingfeeder into a 100ml graduated cylinder and weighing the knownvolume. 4. Ball-panhardness A screened and weighed sampleof granar activated carbon is placed in a special hardnesspanwith a number of stainlesssteel balls,then subjected to a combined rotating and tappingaction for 30min. Degradation of particlesize is determined by measuring the mass of granar activatedcarbonminimun 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.Inorganic supporting andfiltering materials.Methods of test 7.Iodine According to EN12902-Productsused for treatment of water intended human consumption.Inorganic suppotring andfiltering materials.Methods of test
