ASTM D4413-98e1 PDF

1.1 This test method describes the determination of ethylene oxide (oxirane) in workplace atmospheres using charcoal tube methodology.

1.2 This procedure is compatible with low flow rate personal sampling equipment: 10 to 200 mL/min. It can be used for personnel or area monitoring.

1.3 The sampling method develops a time-weighted average (TWA) sample and can be used to determine short-term excursions (STE).

1.4 The applicable concentration range for the TWA sample is from 0.3 to 20 ppm (v/v).

1.5 The applicable concentration range for the STE sample ranges from 1 to 1000 ppm (v/v).

1.6 The values stated in SI units shall be regarded as the standard. Inch-pound units are provided for information only.

1.7 This standard does not purport to address all of the safety problems, 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.
