  • Test item 測試名稱: Virgin granular activated carbon 飲用水處理用產(chǎn)品.粒狀活性碳

    粒徑大于180微米 Particle size greater than 180 microns

     

    Test info 測試內(nèi)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
