2. The following lab test report will show you exactly why Nano Silver dislike bacteria as much as we human does. Overview of Test Environment Date Tested : April 15, 2009 Testing material : PVC Coil mat Testing category: Antibacterial test & Antifungal test
3. - ASTM G-21 (antifungal test) Our First Test What is ASTM G-21? ASTM G 21 is a Standard Practice for Determining Resistance of Synthetic Polymeric Materials to Fungi. DAUFON (regular) 0 0 0 0 1 DAUFON AG+ (Nano silver) 4 0 4 0 2 NO 1 WEEK 2 WEEKS Remarks Resistance Protectivebarrier (mm) Resistance Protective barrier (mm) 3 0 0 0 0 Competitive (Korea) 4 0 0 0 0 Competitive (made in China) Index: Resistance to fungi on the testing sample Resistance level The growth range of mycelium 0 Not found 1 10% of whole size 2 10 ～ 30% of whole size 3 30 ～ 60% of whole size 4 60%~ whole size
4. - ASTM G-21 (antifungal test) Our First Test Conditions The culture ground: NSGA Medium The cultivating period: 2weeks The condition of cultivation : 27℃ Humidity incubator Test material 1 Test material 2 DAUFON AG+ Test material 3 Test material 4 As you can see from Test Material 2 , DAUFON AG+ forms a protective field surrounding it. Therefore, this will stop the attack of fungal to DAUFON AG+. While the other 3 test materials, attracts more fungal and is a good place for fungal to grows.
5. - JIS L 1902 (antifungal test) Our Second Test What is JIS L 1902? JIS L 1902 is testing for antibacterial activity and efficacy on textile products Index: Resistance to fungi on the testing sample Resistance level The growth range of mycelium 0 Not found 1 10% of whole size 2 10 ～ 30% of whole size 3 30 ～ 60% of whole size 4 60%~ whole size DAUFON AG+ (Nano silver) 5 4 2 DAUFON (regular) 0 0 1 NO Escherichia coli Stapylococcus aureus Remarks Protective barrier( ㎜ ) Protective barrier( ㎜ ) 3 0 0 Competitive (Korea) 4 0 0 Competitive (made in China)
6. - JIS 1902 (antibacterial test) Our Second Test (A) As you can see from Test Material 2 , DAUFON AG+ dispel bacterial and forms a “halo” beside it. This clearly shows that not only DAUFON AG+ is antifungal as shown in the previous test, it is also a powerful antibacterial agent. Conditions The culture ground: Nutrient Agar Medium The period of cultivation: 1 Day Relevant mycelium: Escherichia coli Test material 1 (Escherichia coli ) Test material 3 (Escherichia coli ) Test material 2 (Escherichia coli ) DAUFON AG+ Test material 4 (Escherichia coli )
7. - JIS 1902 (antibacterial test) Our Second Test (B) As you can see from Test Material 2 , DAUFON AG+ dispel bacterial and forms a “halo” beside it. This clearly shows that not only DAUFON AG+ is antifungal as shown in the previous test, it is also a powerful antibacterial agent. Conditions The culture ground: Nutrient Agar Medium The period of cultivation: 1 Day Relevant mycelium: Stapylococcus aureus Test material 1 (Stapylococcus aureus) Test material 4 (Stapylococcus aureus) Test material 3 (Stapylococcus aureus) Test material 2 (Stapylococcus aureus) DAUFON AG+
8. Now that you have seen how powerful Silver Nano Technology is, imagine this…. … . Combine Nano Silver Technology and the practical use of carpet, you have the ultimate solution to keep your house clean and free of bacterial. See more at www.daufon.com
