EU extends EN954-1 deadline Pilz advises manufacturers to adopt new standard as soon as possible
Pilz Industrial Automation pointed out in a recent interview that for the simultaneous use of EN 954-1 and EN ISO 13849-1 standards originally scheduled to be terminated on December 28, 2009, the EU has determined to further extend the transition period to years later. Its Official Gazette for this also includes a supplement to EN ISO 13849-1, and in this supplement the superseded standard refers to EN 954-1. The original text reads: 'That is, EN 954-1:1996 will eventually be superseded by EN ISO 13849-1:2008/AC:2009. However, the transition period for the parallel use of EN 954-1 and EN ISO 13849-1 will not be until It was finally discontinued on December 31, 2011. Machine designers and manufacturers may continue to use EN 954-1 under the premise of conformity to the new machinery guidelines. The conformity of order 2006/42/EC is assumed.' Some machine builders may not have implemented and complied with the requirements of EN ISO 13849-1 in their design, verification and documentation due to considerations of the current economic situation, they can now take advantage of This 2-year extension period to accommodate the new standard. After learning of the EU's decision, Pilz said that it believes that the method of probability theory in the new standard can provide designers and users with many benefits when evaluating the reliability of safety systems. Since the new standard can better reflect the latest technological development level of machine safety system design, although EN954-1 can continue to be used for the next two years, Pilz recommends that machine manufacturers adopt the new standard as soon as possible instead of waiting. The end of the transition period is sometimes caught off guard. Despite the increasing sophistication of design calculation requirements, safety calculation tools such as PAScal can be used to calculate the required Performance Register (PL) and Safety Integrity Level (SIL). Pilz also expresses its firm belief that the machines and automation of the future are characterized by flexibility and a modular structure, which will surely provide a higher level of availability and suitability for flexible production equipment. There is no doubt that modern machines and equipment require intelligent safety systems. Pilz also emphasized the following points: 1. EN 954 has been superseded, and machine users and manufacturers who make changes sooner can benefit more. 2. The latest revision to EN 954 dates back to 1996. The new standard can be closer to the essence of the new directive and other new standards. 3. The new standard better reflects the requirements of the functional safety management approach when applying safety systems with programmable devices. 4. Pilz and other major suppliers will provide a high level of support for the new standard in various forms, such as training for the new standard and the latest calculation tool PAScal. 5. At the end of the transition period in 2011, designers and manufacturers who have adopted the new standard will not incur additional costs for design, verification and documentation.
