Security Standards

The required level of safety of machines and mechanisms is achieved through the use of appropriate safety management systems for industrial equipment, including programmable electronic ones. Such systems usually include a variety of security devices for managing industrial equipment settings. Since electronic control systems are currently considered the most promising control systems in this area, the study of the security parameters of their application support determines the relevance of this study. This study analyses the main requirements of IEC 61508 and IEC 62061 standards for compliance with modern safety requirements of embedded and applied software for electronic control systems of machines and mechanisms. This study proposes an algorithm for step-by-step implementation of software for electronic machine control systems in accordance with basic security standards for both built-in and application software. Testing has been determined as the main method of verification of application software. Based on the results of the analysis, it was found that the specification of security requirements, both built-in and application software, should highlight the necessary characteristics of each subsystem, providing information that allows choosing the equipment that meets existing security requirements. Relevant recommendations are given on the specifics of practical application of these standards.

This Paper Will Discuss Some Of The Authors Concerns Regarding The Widely Recognized Industry Safety Standard Published By The American National Standards Institute (Ansi), Ansi A 14.2- 1990- Safety Requirements For Portable Metal Ladders. In This Experts Experience, And Based Upon Research Into Ladder Accidents, The Most Common Cause Of Fall From A Portable Metal Ladder Is The Buckling Failure Of One Of The .Side Rails. A Large Percentage Of Falls From A Portable Metal Ladders Are Attributed To The Sudden Buckling Failure Of One Of The Side Rails, Thereby Causing The User To Fall And Sustain Serious Injuries. Analysis Of The Cross-Section Of The Ladder Side Rails Reveals That The Design Criteria Spelled Out In The Industry Ladder Standards Falls Far Short Of The Safety Factors Commonly Applied To Other Structures Of A Similar Nature Which Are Designed By Mechanical, Structural, Civil And Aeronautical Engineers. Whereas The Commercially Available Metal Ladders Meet Or Exceed The Industry Standard, And Are Therefore Deemed To Be Safe By The Courts, A Thorough Analysis Of The Basis For The Standards Shows Several Inconsistencies And Deficiencies, Some Of Which Will Be Addressed In This Paper.
