ISO/TS 15998 - ISO Functional Safety Standard for Earth-moving Machinery

Performance Criteria and Tests for Functional Safety and Machine Control Systems (MCS) Using Electronic Components

Heavy-Duty Vehicles

The heavy-duty vehicles are specially designed for executing construction tasks, most frequently ones involving earthwork operations.

  • Heavy machines
  • Heavy trucks
  • Construction equipment
  • Engineering equipment
  • Heavy vehicles
  • Heavy hydraulics

They usually comprise five equipment systems; implement, traction, structure, power train, control and information.

ISO/TS 15998- ISO Standard for Earth-moving Machinery

ISO TS 15998 ISO Standard for Earth-moving MachineryThe ISO 15998 has been developed to assist the user of ISO 15998 by defining common earth‑moving machinery features and possible failure modes with the reasonable and consistent levels of safety requirements. It will help the user to know that others will be adopting similar requirements for similar hazardous conditions.

  • ISO/TS 15998-1: Earth-moving machinery -Performance criteria and tests for functional safety
  • ISO/TS 15998-2: Earth-moving machinery - Machine control systems (MCS) using electronic components

The ISO 15998 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.

Functional Safety Standards For Road Vehicle, Railway Applications, Tractors And Machinery, Earth-Moving MachineryElectronic 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.


HMI Products Meet Standards and Performance

Intelligent Embedded Video and Vision Systems Engineering and ServicesIncreasing complexity in the HMI hardware, electronic, and software systems used throughout automotive technologies has increased the complexity of achieving safety compliance for automotive manufacturers. New automotive standards like ISO 26262, released in November of 2011, aim to provide a common standard to measure how safe an automotive system will be in service. The ISO 13849 provides safety requirements and guidance on the principles for the design and integration of safety-related parts of control systems (SRP/CS), including the design of software. And the IEC/EN 62061 provides requirements that are applicable to the system level design of all types of machinery safety-related electrical control systems and also for the design of non-complex subsystems or devices.

AIS promotes standardization of material, facilities, and engineering practices for the purpose of improving Marine, Military, Oil and Gas, Railway, Machinery, Heavy-Duty and Specialty Vehicles safety standards, regulations, operational readiness, reduce total cost of ownership and acquisition cycle time. Industry standards state requirements in performance terms in order to make maximum use of technologies, products, and practices. AIS engineers manage design tools and methods; deliver intelligence, techniques and data; to drive innovation, collaboration and efficiency in product design. Learn More >
