I think there are many people have learnt about the cloth duct tape. So, do you know the certification of it?
Let me introduce one of the certificcation—RoHS to you. Then you will know more about the cloth duct tape.
RoHS is a mandatory standard set by EU legislation. It’s full name is “Restriction of Hazardous Substances”. And the standard was officially implemented on July 1,2006. Mainly used to standardize materials and process standards for electrical and electronic products, and make it more conducive to human health and environmental protection.
The purpose of this standard is to eliminate lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers in electrical and electronic products. Six substances totally.
It is also emphasized that the cadmium content should not exceed 0.01%.
Which six substences?
1.Pb: for example, solder, glass, PVC stabilizer.
2.Hg: for example, thermostats, sensors, switches and relays, bulbs.
3.Cd:for example, switches, springs, connectors, housings and PCBs, contacts, batteries.
4.Cr 6+: for example, metal anti-corrosion coating.
5.PBBS: for example, flame retardant, PCB, connector, plastic case.
6.PBDE: for example, flame retardant, PCB, connector, plastic case.
Now, we all know the details about the RoHS.
