Does anyone have industrial product n-butanol?* * Quality standard GB/T 6027-1998? If you have any, please send me a copy. Thank you very much!
Hello, host, do you need the 1998 version of GB/T 6027? This standard was later replaced by GB/T 6027-2012, and there is even a newer version, so the 1998 version may have been abolished. I suggest you go directly“ * * Search "Standard Full Text Disclosure System" or "Industrial Standard Network" and enter "GB/T 6027" to see the currently valid version, which can generally be previewed or downloaded for free. If you really need to compare old versions, you can go to some standard service websites to find historical archives, but remember to pay attention to the authority. Hope this helps!
If anyone knows, please send me a copy, thank you!
