Standard Guide for Generating a Process Stream Property Value through the 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 guide covers and provides a workflow overview of the necessary steps related to generating a Process Stream Property Value obtained from the application of a process stream analyzer.
1.2 Generating a Process Stream Property Value from the application of a process stream analyzer 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 guide.
1.3 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 and health practices and determine the applicability of regulatory limitations prior to use.
