标准范围

ISO/TS 15998-2:2012有助于解释和应用ISO 15998第一部分中给出的土方机械上使用的电子机械控制系统（MCS）的性能标准和功能安全测试，通过说明危险评估的替代方法，提供信息和应用示例来说明ISO 15998的合规性，澄清ISO 15998的定义、要求和应用，通过安全相关MCS解决危险机器移动的风险，并就ISO 15998第一部分引用的规范性参考文件的使用和关系提供指导。电子MCS是直接影响机器运动的控制系统，即推进（动力运动）、制动、转向、附件和作业机具控制系统。ISO 15998适用于开关、传感器和其他电子设备的机械故障，以及电磁阀的机械故障，如碎屑引起的卡滞（如果风险评估确定有必要，可以使用电磁阀功能的电子故障监测）。辅助机器操作且不改变机器控制的系统和ESA（电气/电子组件）（如监视器、报警器、仪表、灯和雨刮器，以及向操作员提供反馈的系统部分）不在ISO 15998的范围内，不使用电子/电子部件的纯液压、气动和/或机械MCS也不在ISO 15998的范围内，以及机械故障，如车轴断裂、纯机械阀门、轮胎等。

ISO/TS 15998-2:2012 assists in the interpretation and application of the performance criteria and tests of functional safety for electronic machine control systems (MCS), used on earth-moving machinery, given in the first part of ISO 15998, by illustrating an alternative method of hazard assessment, providing information and application examples to illustrate compliance with ISO 15998, clarifying definitions, requirements and application of ISO 15998, in addressing the risk of hazardous machine movements by safety-related MCS, and providing guidance on the use and relationship of the normative references cited in the first part of ISO 15998.Electronic MCS are those control systems that directly affect machine motion, i.e. propulsion (powered motion), braking, steering, attachments and working tool control systems. ISO 15998 is applicable to the mechanical failures of switches, sensors and other electronic devices and to the mechanical failure of solenoid valves such as sticking caused by debris (electronic fault monitoring of the solenoid valve function can be used if the risk assessment determines it is necessary).Systems and ESAs (electrical/electronic subassemblies) that are ancillary to machine operation and which do not alter machine control (such as monitors, alarms, gauges, lights and wipers, as well as those portions of systems that provide feedback to the operator) are outside the scope of ISO 15998, as are purely hydraulic, pneumatic and/or mechanical MCS not using electronic/electric components, and mechanical failures such as broken axles, purely mechanical valves, tyres and similar.
