Both 20808 and 20810 are national standards for toilet paper, but they are issued at different times and in different scopes of application.
The national standard 20808 issued in 2006 is applicable to various types of toilet paper, such as toilet roll paper, extractable toilet paper, boxed toilet paper, etc. It puts forward requirements for the quality of toilet paper, such as softness, water absorption, tensile strength, dust degree and other indicators must meet certain standards. It's like setting up a barrier for toilet paper to make sure it can stand the test in terms of quality.
20810 is a national standard issued in 2019, mainly for toilet rolls and extractable toilet paper, and the scope of use is relatively small. It adds the requirements of the total number of bacterial colonies and coliform bacteria on the basis of 20808, and pays more attention to the hygienic quality of toilet paper. In addition, it also puts forward requirements for the packaging materials of toilet rolls and extractable toilet paper, which should meet the relevant standards for food packaging materials.
As a result, toilet paper of the 20810 standard is more stringent in terms of hygiene quality and safety, but the scope of application is relatively small. If you need to pay more attention to hygiene quality and safety, you can choose toilet paper that meets the 20810 standard; If you need a wider range of applications, you can choose toilet paper that complies with 20808.
Overall, both standards of toilet paper have their advantages and scope of application, and which one to choose depends on individual needs and actual circumstances.
