1.1This practice covers sample-handling and conditioning systems for typical pipeline monitoring instrumentation (gas chromatographs, moisture analyzers, and so forth). The selection of the sample-handling and conditioning system depends upon the operating conditions and stream composition.
1.2This practice is intended for single-phase mixtures that vary in composition. A representative sample cannot be obtained from a two-phase stream.
1.3The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.
1.4This standard does not purport to address all of the safety concerns, if any, associated with its use.
