本文档是供验证器制造商和应用规范开发人员使用的工程文档。本文档描述了对ISO/IEC 15415和符号系统规范中定义的符号质量方法的修改。它定义了替代照明条件、一些新术语和参数、对某些参数的测量和后续分级的修改以及分级结果的报告。本文件旨在评估直接标记零件的符号质量，其中标记直接应用于物品表面，读取设备为二维成像仪。在应用规范允许的情况下，该方法也潜在地适用于由其他方法产生的符号。当在同一扫描环境中扫描直接零件标记(DPM)符号和非DPM符号时，这是合适的。符号等级报告为DPM等级，而不是ISO/IEC 15415等级。

This document is an engineering document intended for verifier manufacturers and application specification developers.
This document 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.
This document 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.
When application specifications allow, this method is also potentially applicable to symbols produced by other methods. This is appropriate when direct part marked (DPM) symbols and non-DPM symbols are being scanned in the same scanning environment. The symbol grade is reported as a DPM grade rather than as an ISO/IEC 15415 grade.
