IEC TS 62998-3:20 23提供了以下方面的指导: -分析不同波长范围的传感器技术、测量方法和SRS中的感测单元布置，分别是SRS中SRS的布置； -安全相关物体的代表性物理特性，适当考虑其材料特性和SRS/SRSS中使用的传感器技术，以在验证和确认期间实现检测能力和可比结果； -分析环境中存在的物体对安全相关物体的干扰以及由此对检测能力的可靠性的影响； -在设计、开发和维护期间使用算法，以实现适当的检测能力和检测的可靠性；-在积分器对一个或多个SRS的积分期间适当使用算法，以改进测量信息的执行或提供从测量信息导出的决策信息。 如果SRS/SRSS使用本文件中未说明的传感器技术，则适用符合IEC TS 62998-1的通用方法。

IEC TS 62998-3:2023 gives guidance on:
- analysis of sensor technologies of different wavelength ranges, measurement methods, and the sensing unit arrangement in an SRS, respectively the arrangement of SRSs in an SRSS;
- representative physical properties of safety-related objects with due consideration of their material characteristics and the sensor technology/technologies used in an SRS/SRSS to achieve the detection capability and comparable results during verification and validation;
- analysis of the interference of objects present in the surrounding on the safety related objects and thereby the influence on the dependability of the detection capability;
- use of algorithms during design, development and maintenance to achieve appropriate detection capability and dependability of detection;
- appropriate use of algorithms during the integration of SRS or SRSS by the integrator to improve execution of measurement information or provide decision information derived from measurement information.
If an SRS/SRSS uses sensor technologies not stated in this document, then the generic approach in accordance with IEC TS 62998-1 applies.
