(Practice)Standard Practice for Generating a Process Stream Property Value through Application of a Process Stream Analyzer
Standard Practice for Generating a Process Stream Property Value through Application of a Process Stream Analyzer
SIGNIFICANCE AND USE
4.1 The standards employed in the Process Stream Analyzer PSPV Generation Flow Diagram each have a specific deliverable that when combined into a single system produces a PSPV enabling the representation of product by process stream analyzer.
4.2 The description of each standard in the process provides the user with an overview of the application of the standard in the process for developing a PSPV.
SCOPE
1.1 This practice covers generating a Process Stream Property Value (PSPV) from the application of a process stream analyzer, which requires the use of several ASTM standards. These standards describe procedures to collect a representative sample, establish and validate the relationship to the primary test method, and calculate a property value with an expected uncertainty. Each standard builds or prepares data, or both, to be used in another standard. The workflow process culminates to produce a process stream analyzer result that represents a user defined batch of product. The sequence in which the standards are to be utilized is defined in this practice.
1.2 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.
1.3 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.
