This standard applies to the determination of oil and liquids pipeline water content in automatic sampling system. By statistical methods. On the " extraction" of a series of independent variables of the system uncertainty and random uncertainty automatic sampling system as defined in the synthesis, the mathematical model to assess the total uncertainty (tolerance). Determination of water tolerance as a sampling frequency, water content and water analysis function of the number, in this standard are in the form of charts are summarized in Figure 6 to Figure 11.

GB/T 23256-2009/ISO /TR9494.1997IntroductionThis standard uses an international viewpoint and method of the current password is given under the common case, the measurement was washed with petroleum pipeline automatic sampling system When body water content evaluation and expression of uncertainty measurement principles, methods and brief steps to make relates to the pipeline automatic sampling system to measure water containing FIELD amount, you can use uniform guidelines on the measurement results and quality assessment, expressed and compared. Measurement Uncertainty about the terminology used in this standard method for estimating uncertainty of measurement methods and measuring the expression of Uncertainty, National Metrology and technical specifications JJF1059-1999 "Evaluation and Expression of Uncertainty in Measurement" inconsistent statements. GB/T 23256-2009/ISO /TR9494.1997 Petroleum liquids pipeline automatic sampling Determination of petroleum liquid water content Statistical evaluation of the performance autosampler1 ScopeThis standard describes the mathematical method to assess the automatic sampling system of total uncertainty for the determination of liquid petroleum pipeline water content automatically Sampling system. Through statistical methods, the system is a series of independent variables points to "extract" automatic sampling system with defined uncertainty and Machine uncertainty synthesis of the mathematical model to assess the total uncertainty (tolerance). Determination of water content tolerance as sampling frequency, water content and water analysis function of the number, in this standard are carried out in the form of charts Summary, 6 to 11.2 Normative referencesThe following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research Whether to use the latest versions of these documents. For undated reference documents, the latest versions apply to this standard.
