The schemes embrace all industries and laboratories and not only guarantee a minimum standard of quality in product or service but also encourage International trade in these two items. Developing countries will only be developing for a limited number of years and the scheme will spread and it is in all parties interests to encourage such spread. The term Quality Assurance is not to be confused with Quality Control which is only a part of assurance because Quality Assurance needs to be what its name means an assurance that every assessment of capability has been undertaken. Since the Quality Assurance that any part offers has to be assessed the assessors must be under the jurisdiction of an independent National or International body who can use their own staff or approved external assessors.
