Inspecting such a large lot, it is also easy to make an error. For example, here at Metal Cutting Corporation, we routinely produce lots consisting of 100,000 parts. Visual inspections - whether with the naked eye or using sophisticated optical tools - are done to detect a variety of surface finish issues in metal parts, from corrosion and contamination to cracks and surface irregularities.īut given the large quantities that most manufacturers work with, it is impractical to spend the amount of time and significant money required to look at 100% of the parts in every lot. Good Reasons to Use Sampling Plans for Inspection That is why manufacturers and their customers rely on a sampling plan in quality control (QC). Yet, 100% inspection eats up significant time and cost - plus it still does not guarantee 100% compliance. We often talk about how important inspections are to the manufacture of small metal parts, helping to ensure the quality of components that make up thousands, if not millions, of products. ISO/IEC 25024 - Measurement of data quality: Defines quality measures for quantitatively measuring data quality in terms of characteristics defined in ISO/IEC 25012.Saving Time and Cost in Small Metal Parts Inspection.ISO/IEC 25023 - Measurement of system and software product quality: Describes a set of measures and provides guidance for measuring system and software product quality.ISO/IEC 25022 - Measurement of quality in use: Describes a set of measures and provides guidance for measuring quality in use.The document describes a set of measures that can be used as an input for the software product quality or software quality in use measurement. ISO/IEC 25021 - Quality measure elements: Defines a set of recommended base and derived measures, which are intended to be used during the whole software development life cycle.Also provides guidance to users for selecting or developing, and applying measures. ISO/IEC 25020 - Measurement reference model and guide: Presents introductory explanation and a reference model that is common to quality measure elements, measures of software product quality and quality in use.Currently, this division consists of the following standards: Presented measures apply to software product quality and quality in use.

The standards that form this division include a software product quality measurement reference model, mathematical definitions of quality measures, and practical guidance for their application. ISO/IEC 2502n – Quality Measurement Division
