How to check standards?
Thread Content
Which website do people usually use to look up standards? For example, how do you look up the standards for chromatography-grade acetonitrile? The ad on Haichuan Network says to check the standards on Gongbiao Network, but it’s charged :lol
Standard Technology Network www.bzjsw.com
There’s a link in the resource section that you can check out; it’s usually available on the HaiChuan Forum. You might find what you’re looking for by seeing how moderator Canghai searches for posts – http://bbs.hcbbs.com/thread-390043-1-1.html
If a comprehensive search for international, foreign, and domestic standards is required, the Standard Museum of the China National Institute of Standardization is one of the best options. This standard library houses standards from over 70 international and regional standardization organizations, including the International Organization for Standardization (ISO), the International Electrotechnical Commission (IEC), and the International Telecommunication Union (ITU), as well as international standards from more than 60 countries such as the United States, the United Kingdom, France, Japan, and Russia ； The standards set by the American Society for Testing and Materials (ASTM) and the Institute of Electrical and Electronics Engineers, as well as all the industry standards issued by China’s Standardization Administration, are also available. You can sign up for various forums; many of these forums are free, such as Haichuan, Xiaomuchong, and China Food Network

Here are two more websites that are not specialized for standard lookup, but on which many standards can still be found: http://www.foodmate.net/ http://www.instrument.com.cn/
