Do you use ISO 13849 or IEC 62061? We need to hear from you! UPDATED

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!

Survey graphicIn 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 ways that the stand­ards are used , the kinds of prob­lems they encounter when try­ing to apply 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 a num­ber of 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! 

The sur­vey closes 31-​Aug-​12 30-​Nov-​12. Take a minute now to com­plete it.
