本测试方法通过施加流体脉动负载使得血管支架处于与体内环境类似的直径膨胀水平来评价血管支架的耐久性能。该方法适用于已经在模拟血管(模拟血管弹性)中扩张的支架测试样品。典型的耐久测试期相当于10年时间(按照每分钟72次心跳计算)或至少3亿8千万次心动周期。本方法适用于金属或合金的球囊扩张支架或自扩张支架。虽然这个测试方法也可用于涂层支架、聚合物支架或降解支架产品,但并不特别针对这些支架所特有的属性。本方法并不推荐用于治疗动脉瘤或外周血管损伤或提供血管通路的覆膜支架或其他导管产品。但其中的一些信息也许可以用在这些产品的评价上。本方法适用于由于典型的周期性血管直径膨胀导致的支架失效,但不涉及动态弯曲、扭转、拉伸、挤压或磨损等导致支架失效的模式。本方法不涉及弯曲血管模型的测试条件。本方法不涉及支架重叠测试条件。本标准并非试图对所涉及的所有安全问题进行阐述,即便需要,也应结合其使用。确立适当的安全健康的操作规范,以及在应用前明确管理权限,是本标准用户自身的责任。

Eurocode 7(1) EN 1997 is intended to be used in conjunction with EN 1990:2002, which establishes the principles and requirements for safety and serviceability, describes the basis of design and verification and gives guidelines for related aspects of structural reliability. (2) EN 1997 is intended to be applied to the geotechnical aspects of the design of buildings and civil engineering works. It is subdivided into various separate parts (see ). (3) EN 1997 is concerned with the requirements for strength, stability, serviceability and durability of structures. Other requirements, e. g. concerning thermal or sound insulation, are not considered. (4) Numerical values of actions on buildings and civil engineering works to be taken into account in design are provided in EN 1991 for the various types of construction. Actions imposed by the ground, such as earth pressures, shall be calculated according to the rules of EN 1997. (5) Separate European Standards are intended to be used to treat matters of execution and workmanship. They are denoted in the relevant sections. (6) In EN 1997 execution is covered to the extent that is necessary to conform to the assumptions of the design rules. (7) EN 1997 does not cover the special requirements of seismic design. EN 1998 provides additional rules for geotechnical seismic design, which complete or adapt the rules of this standard. EN 1997-2 (1) EN 1997-2 is intended to be used in conjunction with EN 1997-1 and provides rules supplementary to EN 1997-1 related to: planning and reporting of ground investigations; general requirements for a number of commonly used laboratory and field tests; interpretation and evaluation of test results; derivation of values of geotechnical parameters and coefficients. In addition, examples of the application of field test results to design are given. NOTE Establishment of characteristic values is covered in EN 1997-1. (2) This document gives no specific provisions for environmental ground investigations. (3) Only commonly used geotechnical laboratory and field tests are covered in this standard. These were selected on the basis of their importance in geotechnical practice, availability in commercial geotechnical laboratories and existence of an accepted testing procedure in Europe. The laboratory tests on soils are mainly applicable to saturated soils. NOTE It is expected that updates of the present standard will gradually include laboratory and field tests covering additional aspects of soil and rock behaviour. (4) The provisions of this standard apply primarily to projects of geotechnical category 2, as defined in 2.1 of EN 1997-1:2004. The ground investigation requirements for category 1 projects are normally limited as the verifications often will be based on local experience. For geotechnical category 3 projects, the amount of investigations required will normally be at least the same as indicated for geotechnical category 2 projects in the following sections. Additional investigations and more advanced tests, related to the circumstances that place a project in geotechnical category 3, may be necessary. (5) The derivation of parameter values is dedicated primarily to the design of pile and spread foundations based on field testing, as detailed in Annexes D, E, F and G of EN 1997-1:2004.
This standard specifies dosimetric methods used in X-ray diagnosis in the context of quality assurance and radiation protection for measuring of dose quantities and technical properties.
The standard contains terms and definitions for the dosimetry in the context of therapeutic and diagnostic applications of ionizing radiation and radiation protection as well.
Requirements for the execution, interpretation and use of results of laboratory tests to assist in the geotechnical design of structures
This standard defines terms used in the plastics industry, including terms and definitions appearing in plastics standards (of ISO/TC 61), and general terms and definitions of polymer science used in all aspects of plastics technology.
This International Standard defines a list of terms used in the field of soil quality. The terms are classified under several main headings: general terms - description of soil - sampling - terms related to the assessment of soils and remediation.
This British Standard gives general recommendations for tree work.It gives guidance on management options for established trees(including soil care and tree felling) and overgrown hedges.NOTE The principles of this standard may also be applied to some shrubs,which can have similar characteristics to trees.This British Standard does not give guidance on carrying out tree surveys or tree inspections. It considers the impact of work on an individual tree in relation to neighbouring trees, but does not cover overall management of tree populations.
