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.
