ASME MFC-13M-2006 封闭管道中流体流量的测量:跟踪法

This Standard defines the use of tracer (dilution) methods in the measurement of single-phase fluid (gas or liquid) flows in closed conduits. This method of measurement is applicable only to single-phase homogeneous fluid mixtures. This Standard was developed to fill the need for a generalized reference based on fundamental principles to measure fluid flow using tracer methods. ISO standards issued in 1977 addressed tracer methods for gas flows; these were withdrawn in 2001, leaving a void on this subject. An internet search on this subject will find a large number of documents, standards, references, consultants, and manufacturers. Most of the papers, standards, and products are for very specific applications and provide detailed guidance only for those needs. This Standard defines the terms and principles needed for intelligent consideration of tracer methods for any application.

Measurement of Fluid Flow in Closed Conduits: Tracer Methods

ASTM E831-06 用热机械分析法测定固体材料线性热膨胀的标准试验方法

Coefficients of linear thermal expansion are used, for example, for design purposes and to determine if failure by thermal stress may occur when a solid body composed of two different materials is subjected to temperature variations. This test method is comparable to Test Method D 3386 for testing electrical insulation materials, but it covers a more general group of solid materials and it defines test conditions more specifically. This test method uses a smaller specimen and substantially different apparatus than Test Methods E 228 and D 696.1.1 This test method determines the apparent coefficient of linear thermal expansion of solid materials using thermomechanical analysis techniques. Related information can be found in Refs. (, ).1.2 This test method is applicable to solid materials that exhibit sufficient rigidity over the test temperature range such that the sensing probe does not produce indentation of the specimen.1.3 The recommended lower limit of coefficient of linear thermal expansion measured with this test method is 5 m/(mC). The test method may be used at lower (or negative) expansion levels with decreased accuracy and precision (see Section ).1.4 This test method is applicable to the temperature range from 120 to 900 C. The temperature range may be extended depending upon the instrumentation and calibration materials used.1.5 Computer or electronic based instruments, techniques, or data treatment equivalent to this test method may also be used. Note 1Users of this test method are expressly advised that all such instruments or techniques may not be equivalent. It is the responsibility of the user to determine the necessary equivalency prior to use. 1.6 SI values are the standard.1.7 This test method is related to ISO 11359-2 but is significantly different in technical detail.This standard does not purport to address all of the safety problems, 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.

JJF 1130-2005 几何量测量设备校准中的不确定度评定指南

作为贯彻JJF 1059-1999《测量不确定度评定与表示》基本概念在校准中应用的指南，本规范适用于几何量测量设备特性评定(校准)活动。本规范目的是给出完成不确定度报告的全部信息，并为测量结果及其不确定度(客户和供货商之间的关系)的国际比对提供基础。 本规范有助于对测量设备计量特性的最大允许误差(MPE)的理解。 本规范采用不确定度管理程序(PUMA)，它是以JJF 1059-1999为基础的用于评定测量不确定度的实用性迭代程序，并且未对JJF 1059-1999的基本概念作任何改变。本规范通常用于下述情况的不确定度评定和给出不确定度报告： —单个测量结果； —两个或多个测量结果的比较； —由一个(或多个)测量设备得到的测量结果与规定的技术指标(即测量仪器或测量标准器计量特性的最大允许误差MPE等)的比较，以判明是否满足要求。 本规范的迭代法基本上基于对不确定度的上界进行评定，即在不确定度评定的各阶段高估其不确定度，高估的程度由迭代次数来控制。为了避免由测量结果作出错误的判断，对不确定度采取故意的高估。高估的程度决定于具体情况下的经济性评价。 在校准活动中，迭代法是以最小的成本来获取最大收益的工具。迭代法或迭代程序在经济性上具有自我调节能力。为了降低校准成本，迭代法是改变/减小测量不确定度的工具。测量不确定度评定和分配中，迭代法使风险、效果和成本之间的协调成为可能。
