Update on EN ISO 13849 – 1 Mandatory Implementation Date

The machinery world con­tin­ues to wait for the European Commission to reveal the new Mandatory Implementation Date for EN ISO 13849 – 1.

The European Commission pub­lished a new Communication relat­ing to the Machinery Directive this past Friday that con­tin­ues the silence from the EC on the man­dat­ory imple­ment­a­tion date for EN ISO 13849 – 1. Communication C 309/​29, the latest update to the list of stand­ards har­mon­ized under the Machinery Directive, indic­ates that EN ISO 13849 – 1 and -2 were noti­fied in the 8-​Sep-​09 Communication, but fails to provide a date for the ces­sa­tion of pre­sump­tion of con­form­ity under the old stand­ard, EN 954 – 1 /​ ISO 13849 – 1 1999. EN 954 – 1 is not lis­ted in the cur­rent doc­u­ment.

MachineBuilding​.net is report­ing that Marie Poidevin from CEN has stated that the pre­sump­tion of con­form­ity under EN 954 – 1 has been exten­ded to 31-​Dec-​2011. Expectations are that an updated list will be pub­lished this week includ­ing a new ref­er­ence to EN 954 – 1 with the new Mandatory Implementation date.

I con­tin­ue to watch this story and will update you as new inform­a­tion is avail­able.

EN 954 – 1 /​ ISO 13849 – 1:2006 Mandatory Implementation Date Change

The EC Machinery Working Group announces the exten­sion of the man­dat­ory imple­ment­a­tion date for EN ISO 13849 – 1:2008.

Regular read­ers will be aware of the con­tro­versy that has sur­roun­ded the man­dat­ory imple­ment­a­tion of EN ISO 13849 – 1:2006, ori­gin­ally sched­uled for 28-​Dec-​09. The EC Machinery Working Group met this week to review the opin­ions of European machinery experts. Following the meet­ing, it was announced that the man­dat­ory imple­ment­a­tion date will be exten­ded by some time, how­ever no date was giv­en.

Some spec­u­la­tion exists about the length of the exten­sion, with some sources say­ing that it could be as little as 12 months to as long as five years. Until the EC revises the dates and pub­lishes them in the Official Journal we won’t have the ‘final word’, how­ever we are hop­ing that an announce­ment will be made to cla­ri­fy the decision and the date.

If you are a machine build­er who has already imple­men­ted EN ISO 13849 – 1:2006 and the val­id­a­tion stand­ard EN ISO 13849 – 2:2006, you are ahead of the game. Your efforts have not been wasted, as your sys­tems already con­form to the require­ments that will even­tu­ally be man­dat­ory for all machine build­ers. For those machine build­ers who have yet to imple­ment these stand­ards, you’ve gained a bit of a reprieve, but you will still be required to imple­ment these stand­ards even­tu­ally. If you have yet to begin imple­ment­a­tion, now is the time.

I will post the new man­dat­ory imple­ment­a­tion dates as soon as this inform­a­tion is avail­able.

More flip-​flopping on EN 954 – 1?

In recent posts I’ve been dis­cuss­ing the changes in the use of EN 954 – 1, Safety of Machinery – Safety Related Parts of Control Systems. Part 1: General Principles for Design. The EU ori­gin­ally announced that this stand­ard was to be with­drawn on 31-​Dec-​09, being replaced by EN ISO 13849 – 1. As you may know, there are sig­ni­fic­ant dif­fer­ences in these two stand­ards.

A later announce­ment from the European Commission repealed

In recent posts I’ve been dis­cuss­ing the changes in the use of EN 954 – 1, Safety of Machinery – Safety Related Parts of Control Systems. Part 1: General Principles for Design. The EU ori­gin­ally announced that this stand­ard was to be with­drawn on 31-​Dec-​09, being replaced by EN ISO 13849 – 1. As you may know, there are sig­ni­fic­ant dif­fer­ences in these two stand­ards.

A later announce­ment from the European Commission repealed the with­draw­al of EN 954 – 1, extend­ing its use until 31-​Dec-​12. This announce­ment was itself with­drawn.

So where do we stand today? Currently, EN 954 – 1 will be with­drawn on 31-​Dec-​09 and will be replaced by EN ISO 13849 – 1, UNLESS this decision is again reversed by the EC in con­sulta­tion with the EC Machinery Working Group. A meet­ing is planned for 7/​8-​Dec-​09 to dis­cuss this situ­ation and to resolve the con­fu­sion.

As a machine build­er, there is only one prudent course of action – imple­ment EN ISO 13849 – 1 in your designs. If the decision remains as it cur­rently stands, then your products will con­form to the require­ments on 31-​Dec-​09 and you will be able to con­tin­ue to ship product to the EU. If the decision is reversed by the EC and EN 954 – 1 remains in use until 2012, then you are three years ahead of the require­ment and should be using that to full advant­age in your mar­ket­ing and sales efforts.
