Standard Practice for Verifying Performance of a Vertical Inclinometer Probe 验证垂直倾角仪探头性能的标准实践
发布日期: 2020-11-01
1.1 本规程描述了三个功能测试,这些功能测试可一起用于验证垂直横向测斜仪探头是否正常工作。 1.2 本规程不涉及探头的校准程序、电子诊断或维修,也不涉及探头机械零件的检查。 1.3 本规程无意取代制造商对测斜仪设备维修和校准的建议,也无意取代用户制定的维护和校准时间表,作为其质量计划的一部分。 1. 4. 单位- 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.5 所有观察值和计算值应符合实践中确定的有效数字和舍入准则 D6026 . 1.6 本实践提供了一组用于执行一个或多个特定操作的说明。本文件不能取代教育或经验,应与专业判断一起使用。并非本惯例的所有方面都适用于所有情况。本ASTM标准不代表或取代必须根据其判断给定专业服务的充分性的谨慎标准,也不应在不考虑项目的许多独特方面的情况下应用本文件。 本文件标题中的“标准”一词仅表示该文件已通过ASTM共识程序获得批准。 1.7 本标准并非旨在解决与其使用相关的所有安全问题(如有)。本标准的用户有责任在使用前制定适当的安全、健康和环境实践,并确定监管限制的适用性。 1.8 本国际标准是根据世界贸易组织技术性贸易壁垒(TBT)委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 测斜仪监测程序通常运行数年或更长时间。在此期间,可以收集数百项调查。通过将每个新调查与基线调查进行比较来处理。 4.2 经过几年的时间,正常磨损会逐渐降低探头生成与基线调查直接可比的新调查的能力。这可能会在一段时间内被忽视,因为读数的质量可能会以非常小的增量下降。 4.3 当将功能测试纳入倾斜仪监测程序时,可以避免读数质量下降。 通过测试的探针可以放心使用。未通过测试的探针应返回探针制造商进行维修。应注意,制造商在温度控制环境中使用高精度电子控制设备校准测斜仪探头。普通用户无法使用此类设备,因此为这些测试建议的通过/失败标准适用于在控制较少的环境中由精度较低的设备产生的典型结果。 注1: 本标准产生的结果的质量取决于执行该标准的人员的能力以及所用设备和设施的适用性。 符合实践标准的机构 D3740 通常认为能够胜任和客观的测试/采样/检查等。本标准的用户应注意遵守惯例 D3740 本身并不能保证可靠的结果。可靠的结果取决于许多因素;实践 D3740 提供了一种评估其中一些因素的方法。
1.1 This practice describes three function tests that together can be used to verify that a vertical traversing inclinometer probe is working properly. 1.2 This practice does not address calibration routines, electronic diagnostics, or repair of the probe, nor does it address inspection of the probe’s mechanical parts. 1.3 This practice is not intended to replace manufacturers’ recommendations for servicing and calibration of inclinometer equipment, nor is it intended to replace maintenance and calibration schedules established by users as part of their quality programs. 1.4 Units— The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026 . 1.6 This practice offers a set of instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice 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. 1.7 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. 1.8 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. ====== Significance And Use ====== 4.1 Inclinometer monitoring programs often run several years or more. During this time, hundreds of surveys can be collected. Each new survey is processed by comparing it to a baseline survey. 4.2 Over a period of years, normal wear and tear can gradually degrade the probe’s ability to produce new surveys that are directly comparable to the baseline survey. This may go unnoticed for some time, because the quality of readings may degrade in very small increments. 4.3 When function tests are incorporated into an inclinometer monitoring program, the degradation of reading quality can be avoided. Probes that pass the tests can be used with confidence. Probes that fail the tests shall be returned to the probe manufacturer for servicing. It shall be noted that manufacturers calibrate inclinometer probes using high-precision, electronically-controlled equipment in temperature-controlled environments. Ordinary users do not have access to such equipment, so the pass/fail criteria suggested for these tests accommodate typical results produced by less precise equipment in a less controlled environment. Note 1: The quality of the result produced by this standard is dependent on the competence of the personnel performing it and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some of those factors.
