Description

1.1 This practice covers information for the storage and use of LPG samples in standard cylinders of the type used in sampling method, Practice D 1265 and floating piston cylinders used in sampling method, Practice D 3700 .

1.2 This practice is especially applicable when the LPG sample is used as a quality control (QC) reference material for LPG test methods, such as gas chromatography (GC) analysis (Test Method D 2163 ) or vapor pressure (Test Method D 6897 ) that use only a few mL per test, since relatively small portable Department of Transportation (DOT) cylinders (for example, 20 lb common barbecue cylinders) can be used. This practice can be applied to other test methods. However, test methods that require a large amount of sample per test (for example, manual vapor pressure Test Method D 1267 ) will require QC volumes in excess of 1000 L if stored in standard DOT cylinders or American Society of Mechanical Engineers (ASME) vessels.
