适用范围

The trace hydrocarbon compounds listed in Table 1 may have an effect in the commercial use of propylene concentrates, and information on their concentration is frequently necessary.

TABLE 1 Molecular Weight and Specific Gravity

Compound	Molecular Weight	Specific Gravity, 60/60
Propylene	42.08	0.5220
Propane	44.09	0.5077

1.1 This test method covers the determination of 5 to 500 ppm each of ethylene, total butylenes, acetylene, methyl acetylene, propadiene, and butadiene in propylene concentrates.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parenthese are for information only.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
