SGS, the world’s leading testing and certification service provider, offers a range of solutions to help manufacturers produce safe, reliable and compliant cell phone sterilizers.
Utilizing its global network of testing laboratories and in-depth regulatory and industry knowhow, SGS can help manufacturers and suppliers of cell phone sterilizers successfully access markets all over the globe. Relevant testing solutions for UV-C light sterilizers include:
• UL 1431 – product safety
• IEC/EN 60335-2-65 – UV emissions
• ISO 21702 – antiviral capabilities of plastics and non-porous surfaces
SGS can also assist with UV-C permissible human exposure, anti-bacterial capabilities, bacterial elimination ratio by UV, and the UV bacteriophage test.
Studies have shown the average cell phone harbors nearly 20,000 bacteria and viruses, more than a public toilet. Cell phones travel everywhere with us, which means they can also come into contact with SARS-CoV-2, the virus that spreads COVID-19.
With the global COVID-19 pandemic reinforcing in the minds of consumers the importance of maintaining hygiene standards, the potential for pathogens to be spread via cell phone has meant many consumers are now looking for ways to clean and sanitize their devices. The advice circulated by governments and the World Health Organization (WHO) reminds us to wash our hands and avoid touching our faces but cell phones cannot, generally, be washed with soap and water and yet they regularly come into contact with our faces.
One possible solution for sterilizing is using UV-C light – the short-wave form of UV electromagnetic radiation, found between visible light and X-rays. It has a wavelength between 100 and 280 nanometer (nm), although commercially available UV-C lights operate between 200 and 280 nm.
It is UV radiation that causes sunburn and the same action that damages our skin will also kill germs by stopping them reproducing. Technically, since viruses are not living organisms, UV-C does not ‘kill’ them, instead it ‘inactivates’ them. As living organisms, bacteria are killed by UV-C light.
One key advantage of using UV light to sterilize products is that, while it is acknowledged to kill or inactive up to 99.9% of bacteria and viruses, it does not allow for them to become resistant. A second advantage is that immediately after a product is treated it can be used safely. Finally, these UV-C light bulbs can easily be fitted into portable devices, such as a secure box into which a cell phone can be placed and then exposed to UV-C light.
It should be noted this form of sterilization works best on flat surfaces and it will not penetrate gaps within the cell phone. To work effectively, surfaces should be cleaned before the application of the UV-C light, since UV-C light penetration is only superficial.
It should also be remembered that, as with the sunburn caused by staying out in the sun too long, if UV-C light is used incorrectly, it can have a carcinogenic effect.
In the US, these products are regulated by the Environmental Protection Agency (EPA). There is no requirement for registration at the federal level, although some states do require registration but not proof of efficacy. It is therefore up to the manufacturer to prove efficacy. If a product fails to be effective, it is the manufacturer or brand that will suffer damage to their reputation.
UV sterilizers are just one of the many cell phone accessories that are becoming big business around the world. In the US alone, the market for cell phone accessories was around USD 28.53 billion in 2018 and it is predicted to rise to USD 74.43 billion by 2026.
