Rapid development of sophisticated control systems for machinery engenders an array of new safety standards that designers must meet. Major revisions already are underway on machinery safety guidelines adopted by the European Committee for Standardization (CEN) in 1996 and updated into an international standard in 1999. That standard deals largely with definitions of safety-related parts and identification of risks in control systems. "It was clear from the response of designers that they required the standard to deal with all of the aspects of the control system," says Paul Makin. He is chairman of the technical committee on machinery safety at the International Organization for Standardization (ISO). ISO and CEN committees are completely revising the current international standard on control system safety, ISO 13841:1999. ISO, meanwhile, is offering designers a guide for applying machinery safety standards. Send an e-mail to sales@iso.ch and request ISO/TR 13849-100. The International Social Security Association is holding a seminar for lecturers and safety experts who train designers in machinery safety. It will be November 29 and 30, 2001 in Strasbourg, France.

Almost every automaker has had to 'pick a side' when it comes to alternative fuel options and ways to divest from a reliance on gasoline. Fiat is looking to back compressed natural gas or liquid propane as an interim solution.
Designing and filling a new type of water bottle might take less engineering work, but the description will help kids understand how science, math, and engineering influence their lives even through things that seem mundane.
Against a backdrop of mounting product complexity and a need to keep a lid on development costs, companies are recognizing a need to make simulation a more integral part of the design process. In response, vendors in the CAD world are building out CAE functionality as part of their CAD suites while simulation vendors are building tighter integrations to leading CAD tools. Keith Meintjes, Ph.D., Practice Manager, Simulation and Analysis at CIMdata, Inc., joins Design News CAD Editor Beth Stackpole in this radio program to explore the new face of integrated CAD and CAE, how companies are benefitting from this tighter partnership between platforms, and how integrating CAE earlier in the development cycle pays off in optimized product designs.
