Seek standard YB/T 505.7-2007
The standard that the poster needs to look for, namely \"YB/T 505.7-2007 Determination of vanadium pentoxide content in vanadium-titanium containing slag – Titrimetric method\", is the latest version; it’s best to purchase it from a standards website.
Go and take a look here: http://www.51zbz.com/biaozhun/41805.html#edown, but the standard you’re looking for cannot be downloaded for now as “some data is still being processed, and the link path may have changed”.
No wonder it can’t be found; there’s no free version of 07 available online, right? If nothing else works, the only option is to buy it.
