New standards for liquefied gas residue levels
Thread Content
Who has the new standard SY/T7509-2014 for liquefied gas residue levels? Please share it. Thank you!
The standard is too new; it can’t be found online, so I can’t help.
The method you are looking for was only made effective and released in 2015; a scanned version requires some effort to obtain. Why don’t you go to the **Technical Quality Supervision Bureau** and use your position to help those who are in need? If you need it urgently, refer to the old version first. The old version of the standard is available online.
