The development of the Machinery Directive has been 30+ years in the making. Most recently the current version of the Machinery Directive (2006/42/EC) created a series of new requirements that impacted the compliance of manufacturers equipment to the directive. Most of these changes became law through implementation into national legislation of the Machinery Directive 89/392/EEC, with a two-year transitional period. The Commission offered interpretive guides but the industry was unclear about these requirements. The evolution of the Machinery Directive over the last decade has spawned new safety and compliance issues. This whitepaper will de-mystify and clearly articulate the requirements for manufacturers of both SEMI and Industrial Automation equipment and machinery.
