For many girls, does a beautiful mobile phone shell make them like it? Especially those pink blingde cases have a broad market. The mobile phone case, also known as the mobile phone case, is an object that we use and touch frequently every day. Children also play and even bite at the entrance. But what you don't know is that some mobile phone cases even have great harm to our health.
Recently, Shenzhen consumer committee, together with Futian District Consumer Committee and other units, commissioned Shenzhen Quality Consumption Research Institute to test the plastic mobile phone shell, and jointly compared 30 mobile phone shells of 28 brands that are hot online and offline.
Based on the actual use scenarios of consumers, the test was conducted on the chemical safety issues concerned by consumers with reference to the reach regulation of the European Union, pops directive and other relevant standards. In addition, consumers often encounter the problem of yellowing and discoloration in the process of using the mobile phone shell. Therefore, ISO 4892-3 standard is also used in this comparative test to test whether the sample is prone to yellowing and discoloration.
Apple and Xiaomi's "black list" and "water drill flash powder" on the mobile phone case exceed 1550 times of lead standard
The results showed that the quality of 23 mobile phone cases exceeded the first-class international standards, and no toxic and harmful chemicals were detected in 201 chemical tests, accounting for nearly 80%. However, 5 mobile phone cases detected toxic and harmful substances, and the content of the detected toxic and harmful substances exceeded the requirements of the standard limit, including some big brands, such as apple, millet, etc. The toxic and harmful substances beyond the limit are mainly concentrated in the content of PAHs, plasticizers and lead.
