EN ISO 12100:2010 Mechanical Safety - General Principles of Design - Risk Assessment and Risk Reduction was officially released on April 8, 2011. The European Technology Committee issued a notice stating that this standard must be incorporated or referenced as the national standard of each EU member state within May 2011. 

EN ISO 12100:2010 falls under the Machinery Directive 2006/42/EC. This standard is classified as a Class A standard and mainly sets requirements for the basic safety of machinery. All machinery within the scope of the Machinery Directive must meet the requirements of this standard: 

1. EN ISO 12100:2010 replaces EN ISO 12100-1:2003, EN ISO 12100-2:2003, and EN ISO 14121-1:2007. These three standards are respectively: 

2. EN ISO 12100-1:2003 Mechanical Safety - Basic Concepts and General Design Principles - Part 1: Basic Terms, Methodology; 

3. EN ISO 12100-2:2003 Mechanical Safety - Basic Concepts and General Design Principles - Part 2: Technical Principles 

4. EN ISO 14121-1:2007 Mechanical Safety - Risk Assessment - Assessment Principles 

The three replaced labels ended in November 2013. Currently, all products can only comply with EN ISO 12100:2010. 

EN ISO 12100:2010 can be regarded as a combination of EN ISO 12100-1:2003, EN ISO 12100-2:2003, and EN ISO 14121-1:2007. For mechanical products, only the names of the reference standards have been changed, while the substantive content remains largely unchanged. That is to say, the basic requirements and assessment principles are basically consistent with the old standards. The reporting format has been simplified significantly compared to the previous three old standards, but the reporting format itself is completely different from the old standards and is a completely new form.
