- Routinely, a sample piece of a treated fabric is extracted and sent to a US lab (Internationally Recognised) and a Singapore Accredited Laboratory for Biological Testing on selected bacteria strains
- According to the test method ASTM E2149-10, the sample fabric is placed inside a flask filled with bacterial solution
- By shaking the flask continuously for 1-24hrs (simulating how our clothes actually kill the bacteria build up on our skin flora), the result is a bacterial reduction efficacy of 70-99.99% .
- The same test is repeated again twice, after the sample fabric is washed (after 10 times and after 20 times)
- The desired efficacy after repeated launderings should still achieve more than 70% to qualify as a good treatment process
- In addition, the treated fabric is also checked for uniformity in antimicrobial performance

Extensive toxicology tests were done; see below some of the key areas where testing has been carried out on-
- Oral Toxicology
- Eye Contact
- Eye Irritation
- Skin Irritation
- Skin Absorption
- Dermal Toxicity
- Skin Contact
- 3-week vaginal irritation study
- 32-day human wear test with treated socks
- 3-month human wear test with athletic socks
- Inhalation
- Mutagenicity
- Environmental
With the tests results achieved, the antimicrobial technology has successfully earned numerous safety and performance certification, accreditation with international standards and governmental regulatory agencies:
