12 Notes for designing, programming, validating and testing safety-
related applications
The following notes describe the procedures for designing, programming, validating and
testing safety-related applications
The notes are intended to assist the user in arranging, clearly understanding and applying all
steps from the risk assessment to the system test. For improved understanding of the related
points, the individual steps are explained in more detail based on examples.
12.1 Risk assessment
In principle the manufacturer of a machine must ensure the machine designed and supplied is
safe. The related applicable directives and standards are to be used for the assessment. The
goal of the safety assessment and the resulting measures derived must be the reduction of the
hazard for persons to an acceptable level.
The analysis of the hazards must take into account all operating states of the machine such as
operation, setting up and servicing or installing and decommissioning, as well all foreseeable
misuse.
The necessary procedure for the risk assessment and the measures for the reduction of the
risk are given, e.g., in the applicable standards
EN ISO 13849-1 Safety of machinery
EN ISO 61508 Functional safety of electrical/electronic/programmable electronic safety-related
systems.
