Safety of machinery - Safety-related parts of control systems - Part 2 : validation
ISO 13849-2:2003 specifies the procedures and conditions to be followed for the validation by analysis and testing of:the safety functions provided andthe category achievedfor the safety-related parts of the control system in compliance with EN 954-1 (ISO 13849-1), using the design rationale provided by the designer.This International Standard does not give complete validation requirements for programmable electronic systems and therefore can require the use of other standards.
ISO 13849-2:2003 specifies the procedures and conditions to be followed for the validation by analysis and testing of:
- the safety functions provided and
- the category achieved
for the safety-related parts of the control system in compliance with EN 954-1 (ISO 13849-1), using the design rationale provided by the designer.
This International Standard does not give complete validation requirements for programmable electronic systems and therefore can require the use of other standards.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
