SIGNIFICANCE AND USE 5.1 Analyzer systems require representative samples of petroleum products delivered in a timely manner to (1) facilitate the control of process or blending units or (2) calculate a flow proportioned property value. 5.2 Representative 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. 5.3 Representative samples of petroleum products are tested to determine the chemical and physical properties of a batch offered for tender. SCOPE 1.1 This practice covers the performance requirements for sample systems employed to deliver process stream samples (1) to analyzer system for analyses or (2) for analyzer validation or (3) for composite sample systems. It also outlines the selection and operation of line or batch sampling equipment intended for analyzer flow proportioned average property value system validation. Sample handling, mixing, and conditioning procedures are required to ensure that a representative sample of the liquid petroleum product is collected from the sampling source. 1.2 Applicable Fluids—This practice is applicable to single liquid phase petroleum products whose vapor pressure at sampling and sample storage conditions is less than or equal to 110 kPa (16.0 psi), and, with a D86 final boiling point less than or equal to 400 °C (752 °F). 1.2.1 Specialized sample handling may be necessary to maintain sample integrity of more volatile materials at high temperatures or extended residence time in the receiver. Such handling requirements are not within the scope of this practice. Users should consult the analytical methods to be performed on the sample for special sample storage or conditioning requirements. 1.3 Some 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. 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This 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.
Abstract
Overview
ASTM D7453-22 establishes the standard practice for the sampling of petroleum products for analysis by process stream analyzers and for validating process stream analyzer systems. Developed by ASTM International, this practice defines methods and requirements necessary to deliver representative samples to analyzer systems, enabling accurate analysis and calibration in petroleum product processing and blending operations. The standard applies to single-phase liquid petroleum products under specific vapor pressure and boiling point constraints, ensuring consistency and reliability in chemical and physical property determinations.
Key Topics
- Representative Sampling: The standard outlines essential requirements for collecting representative samples, crucial for determining chemical and physical properties of petroleum products and for the validation of analyzer systems.
- Sample Handling, Mixing, and Conditioning: Guidance is provided on proper handling, mixing, and conditioning to maintain the integrity of samples during collection, storage, and transport. This is necessary to ensure that sampling does not alter the critical properties under analysis.
- Sampling Methods: Coverage includes selection and operation of both line and batch sampling equipment, with detailed procedures for sample point location, flushing, container handling, and system mixing to minimize lag time and sample alteration.
- Automatic and Composite Sampling: Requirements for automatic sampling systems are addressed, including flow-proportioned sampling, grab volume consistency, accumulator management, and system validation principles.
- Probes and Installation: Best practices for probe location and design are included to secure reliable and consistent samples from pipelines, considering stream conditioning and equipment compatibility.
Applications
ASTM D7453-22 is utilized extensively in refineries, chemical plants, terminal operations, and laboratories involved in the processing, blending, and quality assurance of petroleum products such as gasoline, diesel, jet fuel, and biofuels. Key applications include:
- Process Stream Analysis: Ensuring timely and representative samples are delivered to online analyzers for real-time control of process or blending units.
- Analyzer System Validation: Collecting and analyzing samples to validate the calibration and performance of process stream analyzers according to recognized primary test methods.
- Batch Quality Testing: Gathering composite samples during transfers or blending operations to determine batch properties and validate flow-proportioned average property values.
- Regulatory Compliance: Supporting compliance with industry, safety, and environmental requirements for sampling, analysis, and documentation of petroleum products.
