2.5-Day Course Overview

This course will cover functional safety standards and concepts related to earth moving machinery.

Applicable standards covered in this training include the EU Machinery Directive, ISO 13849, Safety of Machinery – Safety-Related Parts of Control Systems, and ISO 25119:2018, Tractors and machinery for agriculture and forestry – Safety-related parts of control systems. UL experts will cover such topics as hazard identification and risk assessment in accordance with ISO 12100:2010, Safety of Machinery – General principles for design – Risk assessment and risk reduction. Case studies on a range of topics, including motor drives and safety product life cycles, will also be used to provide examples of how the requirements and concepts of the standards are applied.
