ASTM D2713 – Standard Test Method for Dryness of Propane (Valve Freeze Method)
Description:
Significance and Use
5.1 This test is a functional test in which the water concentration in the product is related to product behavior characteristics in a pressure-reducing system of special design to arrive at a measure of product acceptability in common use applications. Experience has demonstrated that excessive water content (dissolved water) will cause freeze-up difficulties in pressure reducing systems.
Scope
1.1 This test method covers the measurement of the dryness of propane products that do not contain antifreeze agents such as, but not limited to, commercial propane and special duty propane (see Specification D1835).
1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
