Documento di confronto tra la nuova norma ISO 14120 e la norma che sarà sostituita EN 953

Explaining the differences between ISO 14120 and EN 953

The Introduction to ISO 14120 has been redrafted, giving a better explanation of Type-A, Type-B and Type-C standards, and stating that ISO 14120 is a Type-B2 standard (EN 953 only referred to itself as a Type-B standard). 

Whereas EN 953 makes it clear that the designer shall manage risks by identifying risks, assessing those risks and reducing risks by design before considering safeguards, ISO 14120 makes no reference to risk management in the Introduction, except to say that guards provide a risk reduction for both protection against unintended access and against ejected parts and substances, and that guards can also protect against other hazards such as noise, fire, biological hazards and radiation. 

Note, however, that clause 4, Risk assessment, remains virtually unchanged.
