This is especially so as Regulation 10 of the Provision and Use of Work Equipment Regulations 1998 (PUWER) requires that an employer must ensure that any equipment subject to European Directives complies with the EHSRs
of the Directives that apply to it.
However, if a manufacturer chooses to follow CEN design standards, the design is presumed to conform to the relevant EHSRs. If a designer chooses another standard, the manufacturer, if challenged by a European authority, must demonstrate how that standard meets the safe design level prescribed by a corresponding CEN standard.
Instead, designers find the "Essential health and safety requirements (EHSR)." Using generic terms, the purpose is to cite possible machine hazards and design objectives to protect the machine users.
