0概述对于检测实验室,检测报告就是它的产品,同样有一个质量形成过程。为了确保检测数据的准确可靠,就必须明确它的质量形成过程和过程的各个阶段可能影响检测报告质量的各项因素,例如环境条件、执行标准、人员素质、仪器设备、样品处置等,从而对这些因素实行有效的控制和管理,以保证检测报告的质量。本文针对本实验室的检测流程,对质量形成过程进行分析。本实验室的检测活动大致分为三个阶段:准备阶段、实施阶段、核查阶段。各个阶段控制内容的侧重点不同。参见图1检测工作质量保证体系图。图1检测工作质量保证体系图1环境条件的识别与控制… 相似文献

在实验室进行的各项活动中,计量检测过程和计量检测结果是影响质量控制的两大主要因素,质量管理就是通过控制与这些相关的因素来实现。按照过程质量控制因素和结果质量控制因素的分类,对在计量检测中影响质量控制的因素提出改进措施,以期提高计量检测的能力和服务水平,提高实验室的整体能力。指出检测过程控制一般从设施环境、测量设备、检测人员、检定和校准及检测方法的选择等不同途径进行控制,检测结果的质量控制主要包括原始记录、证书报告和实验室能力验证对质量控制的影响等。 相似文献

经过一系列规定动作形成的检定、校准证书或报告(以下简称"证书"或"报告")承载了检定、校准过程和结果的主要信息。当客户对证书、报告内容或其形成过程的感知质量(效果)低于认知质量(要求)时,便会产生投诉(或抱怨)。客户投诉处理关系到计量检定机构的形象和检测事业的发展,应当予以足够的重视。但在笔者接触和参与的法定计量检定机构考核和监督检查中,发现很多基层法定计量 相似文献

质量管理是环境监测站管理工作的中心环节,实施新的《评审准则》是将质量管理放在首位。这就要建立以质量为核心的管理体系,同时要形成新的质量观念,对检测的全过程实施质量控制,以预防为主,对检测报告质量有影响的多种因素都要形成文件化的质量体系进行控制。通过内部审核,发现质量体系实施中的问题;通过管理评审,由站长确认问题,做出决策;再通过纠正措施和预防措施来解决问题,从而形成一个不断实施质量改进的环境监测站自我完善机制。 相似文献

检测机构是依据标准用科学的检验方法对产品或样品进行检验,取得准确的数据和结论,出具检验报告来公正、客观地评价产品或样品的质量水平。影响检测报告质量的因素是多方面的。本文从样品采集和检验全过程控制及报告编制审核等各方面,对如何保证检测报告的质量进行阐述,从而真正有效地促进检测工作质量的不断提高。 相似文献

工程质量的优劣,对工程能否正常运行关系重大,它不仅影响业主的利益,也影响承包商的信誉。同时也反映监理工作的好坏。施工监理工程师的质量控制,实际上是监理工程师组织承包商按合同规定标准进行施工,并对形成的质量因素进行检测、核验,对差异提出调整以及纠正措施的监督管理过程。 相似文献

A field failure in certain products has the potential to cause human suffering and/or loss of life. To the manufacturer, these failures will result in a significant external failure cost. In this paper, cost minimization models are developed to determine an optimal inspection system for multiple 100% attribute inspections with inspection error. An example involving the visual inspection of a braze joint in a cardiac biopsy device is presented to illustrate the use of the models. A key result is that a system requiring an item to pass every inspection in order to be shipped to a customer is not always the best alternative. Examples illustrating the sensitivity of the model results to key cost and operational parameters are shown. 相似文献

The Effects of Inspection Error on a Complete Inspection Plan 总被引:1,自引:0,他引:1
In a complete inspection plan, every incoming item is subject to variable inspection. If the inspection result indicates that an item fails to meet predetermined specification limits, the item is reworked so that its quality characteristic is exactly equal to the target value. The specification limits are determined by the tradeoff among the cost incurred by imperfect quality, cost of rework and cost of inspection. The economic and statistical effects of inspection error on the complete inspection plan are investigated. Two models with considerations of inspection error are developed under different rework schemes, then compared with the model without inspection error consideration. 相似文献

Five different optimum procedures are presented for inspection plans which do not directly measure the quality characteristic sought. Four of these plans are based on well-known criteria frequently used in applications of statistical decision theory. A fifth procedure maximizes, among other things, the probability that all defective items in a batch are removed among a fixed number, N, chosen for removal. This procedure replaces the problem of deciding which criterion to use with how many items one can afford to remove. 相似文献

Quality control of materials and structures is an important issue, also for GLARE. During the manufacturing stage the processes and materials should be monitored and checked frequently in order to obtain a qualified product. During the operation of the aircraft, frequent monitoring and inspections are performed to maintain the quality at a prescribed level. Therefore, in-service inspection methods are applied, and when necessary repair activities are conducted. For the quality control of the GLARE panels and components during manufacturing, the C-scan method proves to be an effective tool. For in-service inspection the Eddy Current Method is one of the suitable options. In this paper a brief overview is presented of both methods and their application on GLARE products. 相似文献
