What is ISO/IEC 29158 about?
ISO/IEC 29158 is an International Standard on automatic identification and data capture techniques which is based on is an engineering document intended for verifier manufacturers and application specification developers.
ISO/IEC 29158 describes modifications to the symbol quality methodology defined in ISO/IEC 15415 and a symbology specification. It defines alternative illumination conditions, some new terms, and parameters, modifications to the measurement and subsequent grading of certain parameters, and the reporting of the grading results.
ISO/IEC 29158 was developed to assess the symbol quality of direct marked parts, where the mark is applied directly to the surface of the item and the reading device is a two-dimensional imager.
Who is ISO/IEC 29158 for?
BS ISO/IEC 14651 on DPM is relevant to:
- IT industry
- Manufacturers of DPM readers
- Product design engineers
- Automotive industry
- Electronics industry
Why should you use ISO/IEC 29158?
DPM are codes, symbols, and text that are etched or printed directly onto the surface of a part instead of affixed by a label.
ISO/IEC 29158 is helpful as it provides more accurate and reliable part identification. As related to quality guidance it is important for symbologies such as data matrix, which is specified to contain smooth continuous lines but can be marked with disconnected dots in DPM applications.
ISO/IEC 29158 is beneficial as it utilized to capture key information from surveys, invoices, claim forms, unstructured documents, and other document types.
Overall, you can prevent poor contrast of DPM codes that hinders reliable identification, thus ensuring enhanced traceability through the product’s lifecycle. You can also do away with challenges arising from variability and surface imperfections.
What’s changed since the last update?
BS ISO/IEC 29158:2020 replaces ISO/IEC TR 29158:2011, which has been technically revised. The main changes compared to the previous edition are as follows:
- Inclusion of continuous grading
- Expanded grading levels for minimum reflectance
- Inclusion of a tilted lighting and camera position
- Reorganized proposed lighting options
