ASTM D7453-22

5.1Analyzer systems require representative samples of petroleum products delivered in a timely manner to 5.2Representative samples of petroleum products are required for the determination of chemical and physical properties. These properties are used to establish the relationship between the analyzer system and the primary test method during initial and ongoing validation of the system.

5.3Representative samples of petroleum products are tested to determine the chemical and physical properties of a batch offered for tender.

1.1This practice covers the performance requirements for sample systems employed to deliver process stream samples (1) to analyzer system for analyses or 1.2Applicable FluidsThis practice is applicable to single liquid phase petroleum products whose vapor pressure at sampling and sample storage conditions is less than or equal to 110kPa (16.0psi), and, with a D86 final boiling point less than or equal to 400C (752F).

1.3Some or all of the processes outlined in this practice may be applicable to other liquids. Applying this practice to other liquids will require the consideration of additional methods and practices. It is the responsibility of the user of this standard to identify any and all applicable safety and sampling considerations and establish appropriate procedures to handle these additional considerations.

1.4The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.5This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
