ASME B31J-2017 金属管道构件的应力强化系数（i因子）、柔韧性因子（k因子）和标准试验方法

The ASME B31 Code for Pressure Piping and the ASME Boiler and Pressure Vessel Code, Section III, Nuclear Components, Subsections NC and ND piping rules require the use of stress intensification factors (SIFs or i-factors) and flexibility factors (k-factors) when checking the adequacy of components and joints (welded and nonwelded) in piping subject to various loads, including cyclic loads, that may produce fatigue failures. As used herein, where the word Code is used without specific identification, it means the Code that incorporates or references this Standard. Experimental methods to determine SIFs, flexibility factors, and sustained load factors are provided in the Nonmandatory Appendices. Compiled stress intensification and flexibility factor equations for common piping components are included in Table 1-1; see also Tables 1-2 and 1-3 and Figures 1-1 through 1-7. ASME B31 压力管道规范和 ASME 锅炉和压力容器规范第 III 部分，核部件，NC 和 ND 管道小节规则要求在检查承受各种载荷的管道中的组件和接头（焊接和非焊接）的充分性时使用应力增强系数（SIF 或 i 系数）和柔韧性系数（k 系数），包括可能导致疲劳失效的循环载荷。如本文所用，如果使用“代码”一词而没有特定的标识，则是指包含或引用本标准的“代码”。非强制性附录中提供了确定 SIF、柔韧性系数和持续荷载系数的实验方法。常见管道构件的应力强化和柔韧性系数方程包含在表 1-1 中;另见表1-2和1-3以及图1-1至1-7。

ASTM D8081-17 使用直接剪切电池获取可靠和准确的散装固体流量数据的理论和原则的标准指南

1.1 This guide covers theory and principles for obtaining reliable and accurate bulk solids flow data using a direct shear cell. It includes characteristics and limitations of the three most popular direct shear cell types: Translational (D6128), Annular (D6773), and Rotational (D6682 and D7891). 1.2 Units—The values stated in SI units are to be regarded as standard. No other units of measure are included in this standard. 1.3 This guide offers an organized collection of information or a series of options and does not recommend a specific course of action. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this guide may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project’s many unique aspects. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process. 1.4 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. 1.5 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.
