Validation plan
Introduction
ISO/IEC 13849:2003 is a standard that specifies the procedures and guidelines to be followed for the validation through analysis and testing of appropriate security functions to ensure security in control systems. However, this International Standard does not provide complete validation requirements for programmable electronic systems, and therefore may require the use of other standards that complement it. The status of this standard is currently retired and its publication date was August 2003.[1].
Standard Categorization
According to its origin
Depending on its origin, this standard is categorized as a de Iure or Jure standard, since it is a formal and legal standard agreed upon and supported by an authorized international standardization body such as ISO (International Organization for Standardization).
This standard has been developed by the Technical Committee ISO/TC 199 "Safety of machinery" [2] belonging to the International Organization for Standardization and has been assumed as EN ISO 13849-2:2008 by the Technical Committee CEN/TC 114 "Safety of machinery" whose secretariat is in the hands of DIN.
The activity of the ISO/TC 199 Technical Committee is based on the standardization of basic concepts and general principles for machinery safety that incorporates terminology, methodology, protections and safety devices within the framework of ISO/IEC Guide 51 and in cooperation with other technical committees of ISO and IEC.[1].
According to your application possibilities
This standard is considered open because its basis is cooperation and consensus among a group of people, allowing said people to share information freely. Furthermore, for the approval of this standard, the approval of 75% of the national organizations was necessary.
On the other hand, this standard could be considered in certain aspects as closed since to obtain its documentation the corresponding payment must be made.
However, what really determines our consideration of the standard is that we are not obliged to pay royalties for its use, therefore, it is considered an open standard.
