T/CMES 16001-2019 海底管道悬跨和偏移安全评定

本标准规定了海底管道悬跨和偏移安全评定术语。 本标准适用于波浪、海流作用下海底管道悬跨和海床移动引起的海底管道偏移的安全评定。 本标准适用于圆形截面海底管道，然而只要其他流体力学载荷现象例如驰振适当考虑了，也可以用于非圆形截面管道。

EN IEC 62402:2019 报废管理

IEC 62402:2019 provides requirements and guidance for obsolescence management applicable to any organization that is dependent on another organization to obtain value from the usefulness of the items that it provides. A cost-effective obsolescence management process and the activities used to implement the process are applicable throughout all phases of an item’s life cycle. This document covers the following areas: • establishing an obsolescence management policy; • establishing an infrastructure and an organization; • developing an obsolescence management plan (OMP); • developing strategies to minimize obsolescence during design; • determining an obsolescence management approach; • selecting obsolescence resolution and implementation; • measuring and improving the performance of the outcomes of the obsolescence management activities. Guidance on obsolescence management is included as notes, in the informative annexes and references in the Bibliography. This second edition cancels and replaces the first edition published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) this document has now been written with requirements as a standard, not a guide; b) this document continues to have guidance in the informative annexes; c) this document has been written as a general process for all technologies and items. Keywords: obsolescence management

ASTM D5592-94(2018) 使用塑料进行工程设计所需材料特性的标准指南

1.1 This guide covers the essential material properties needed for designing with plastics. Its purpose is to raise the awareness of the plastics community regarding the specific considerations involved in using the appropriate material properties in design calculations. 1.2 This guide is intended only as a convenient resource for engineering design. It should be noted that the specific operating conditions (temperature, applied stress or strain, environment, etc. and corresponding duration of such exposures) could vary significantly from one application to another. It is, therefore, the responsibility of the user to perform any pertinent tests under actual conditions of use to determine the suitability of the material in the intended application. 1.3 The applicable ISO and ASTM standard methods for the relevant material properties are listed in this guide for the benefit of design engineers. 1.4 It should be noted that for some of the desired properties, no ASTM or ISO standards exist. These include pvT data, no-flow temperature, ejection temperature, and fatigue in tension. In these instances, relying on available test methods is suggested. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 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. NOTE 1—There is no known ISO equivalent to this standard. 1.7 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.
