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.<\/p>\n

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.<\/p>\n

\n

NOTES<\/b><\/p>\n

    \n
  1. \n

    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.<\/p>\n<\/li>\n

  2. \n

    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.<\/p>\n<\/li>\n<\/ol>\n<\/blockquote>\n
