详细介绍

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
