1) The density can also be calculated using the method in GB/T 12576 but is measured as stipulated in SH/T 0221 through arbitration.
2) The vapor pressure can be calculated using the method in GB/T 12576 but is measured as stipulated in GB/T 6602 through arbitration.
3) According the method in SY/T 7509, drop 0.3mL solvent residue mixture on filter paper with the increment of 0.1mL each time; after 2min, observe under daylight; if there is a lasting oil ring, this indicates passing.
4) Determine whether the test sample has free water using the visual method while measuring the density. |
III. Application: Used for civil and industrial liquefied gas.
IV. Storage: Canned
V. Storage and transportation: LPG can be transported with railway tankers, automobile tankers, steamboat cabins and pipelines.
