Conformity assessment is the demonstration that specified requirements relating to a product, process, system, person or body are fulfilled” [ISO/IEC 17000:2004]. The choice of conformity assessment scheme should take account of the risks of non-compliance with the applicable specifications. If the risks concern safety or health there is likely to be a greater case for a mandatory conformity assessment scheme whereas if non-compliance with a particular specification results in non-optimal performance then a simpler, less formal and so less expensive, conformity assessment scheme may be more appropriate.
