This International Standard describes a procedure for the assessment of whether liquefied petroleum gas (LPG)
hydrocarbons consisting predominantly of propane and/or propene are sufficiently dry to avoid malfunctions in
pressure-reducing systems installed in domestic, industrial and automotive LPG applications.
The test is normally used as a functional pass/fail test in which the behaviour of the product is assessed in a
specially designed and calibrated regulator valve.
NOTES
1 If excessive dissolved water is contained in the LPG under test, it will cause freezing and blockage of a test regulator valve,
which is an indication that the product could cause malfunctions in commercial pressure-reducing systems.
2 If the product under test contains an antifreeze agent, the time taken for the test valve to freeze is not necessarily a function
of dryness, but may provide an indication of the tendency of the product to cause freezing in pressure-reducing regulators
under service conditions.
