This document provides normative tables of machine performance levels required (MPLr) by common function and type for earth-moving machinery (EMM) as defined in ISO 6165. These MPLr can then be mapped or applied to safety control systems (SCS) used to control or that affect the functions defined in the table.The MPLr in this document are determined through the machine control system safety analysis (MCSSA) process outlined in ISO 19014-1. A brief explanation of how the levels were derived and the associated assumptions are contained herein.This document is not applicable to EMM manufactured before the date of its publication.

ISO 15998:2008 specifies performance criteria and tests for functional safety of safety-related machine-control systems (MCS) using electronic components in earth-moving machinery and its equipment, as defined in ISO 6165.
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.
