摘要
在许多行业中,无损检测(NDT)在质量保证和确保可靠的持续运行方面发挥着重要作用。因此,对检测结果进行可靠性评估的重要性与日俱增。目前的标准和法规为此提供了几种方法。例如,DIN EN ISO/IEC 17025:2018-03提供了确定测量不确定度的一般要求。相比之下,与方法相关的标准,如DIN ISO 19828:2021-03,在考虑环境条件和其他因素(例如检验人员的经验)的情况下,规定了目视检验(VT)的详细要求。相比之下,VDA第5卷将目视检查定义为一种属性方法,使得测量不确定度的确定变得不必要。相反,检验过程的可靠性是通过能力测试来评估的。本文在以往实验的基础上,考察了法规方法在考虑目视检测可靠性时的适用性和适用性。结果表明,单个测量值(例如照度)不适用于此目的。此外,还表明,孤立地考虑人为因素(例如检查员的培训或经验)也不够合适。因此,通过对参考对象的熟练程度测试来确定检验方法的资格,并应用Cohen’s kappa来评价人为因素似乎更适合于所调查的问题。
Approaches to assess reliability in visual inspection
Non-destructive testing (NDT) plays an important role in quality assurance and ensuring reliable ongoing operations in many industries. Thus, the importance of reliability assessment of inspection results is increasing. Current standards and regulations provide several approaches for this purpose. For example, DIN EN ISO/IEC 17025:2018-03 provides general requirements to determine measurement uncertainty. In contrast, method-related standards such as DIN ISO 19828:2021-03 specify detailed requirements for visual inspection (VT), considering environmental conditions and other factors (for example experience of the inspection personnel). In contrast, VDA Volume 5 defines visual inspection as an attributive method, making measurement uncertainty determinations unnecessary. Instead, the reliability of the inspection process is evaluated by proficiency tests. This paper examines approaches of regulations, based on previous experiments, for their applicability and suitability for considering the reliability of visual inspections. It is shown that individual measurement values (for example illuminance) are not suitable for this purpose. Furthermore, it is shown that human factors (HFs) (for example training or experience of the inspector), considered in isolation, are also not sufficiently suitable. Hence, the combination of the qualification of inspection methods, by means of proficiency tests on reference objects, and the application of Cohen's kappa for evaluating human factors appeared to be more suitable for the investigated issue.
