Do you use ISO 13849-1 or IEC 62061 to define and analyze the safety-related parts of the control systems used on your machinery? Have you been frustrated by trying to apply these standards? Good news! ISO and IEC are working on merging these documents, but the committee working on the merger needs some guidance from users. Here’s your chance to be heard!
In May this year, ISO TC199 launched an online survey asking for input from machine builders and anyone else that uses ISO 13849 or IEC 62061. The survey probes the ways the standards are used, the problems they encounter when applying them, and how the use of these standards affects their products and businesses. The survey, titled “Design of safety-related controls/control systems for machinery — Experiences with generic standards (in particular ISO 13849-1 and IEC 62061),” asks several important questions that will guide the Joint Working Group 1 (JWG1) as work proceeds on merging ISO 13849 and IEC 62061.
The survey covers:
- The generic and machine-specific standards used in your company;
- The types of control technologies used in your products;
- Challenges with getting component reliability data;
- Use of ‘well-tried components,’ and the methods to qualifying components as ‘well-tried’;
- Challenges related to integrating?mechanical, pneumatic or hydraulic components in the design of the safety-related controls, and the specific challenges you have with this, as well as the means you have developed to overcome these challenges;
- The sources you use for failure rate data;
- The influence of?accident/incident history on your designs;
- Methods used to determine PLs or SILs;
- The use of designated architectures in your designs;
- The use of diagnostics;
- Verification and validation procedures;
- Use of Common Cause factors; and
- The use of design software tools like SISTEMA, PasCAL or SET
As you can see, it’s pretty wide-ranging. If you have a few minutes and would like to contribute to the future development of these standards, the Joint Working Group would like to hear from you!?
