Eyeballing
1
：
gaseity content , total sulfur content is at 0
℃、
101.35kPa.
2
：
can measure sample whether it exists free water by eyeballing when measuring density.
a
evaporation pressure can be evaluated by GB/T 12576
，
measured by GB/T 6602 when arbitration
。
b
component can be measured by SH/T 0230
，
but measure by SH/T 0614 when arbitration.
c
density can be measured by GB/T 12576,but measured by SH/T 0221 when arbitration.
d
Total sulfur content can be measured by SY/T 7508
，
but measured by SH/T 0222 when arbitration.
