4、準化問題.隨著國際貿(mào)易的發(fā)展,對國際標準的要求日益提高，ISO的作用也日趨擴大，世界上許多國家對ISO也越加重視.ISO的目的和宗旨是:在世界范圍內(nèi)促進標準化工作的發(fā)展,以利于國際物資交流和互助，并擴大在知識、科學、技術(shù)和經(jīng)濟方面的合作。ISO is a network of the national standards institutes of 148 countries, on the basis of one member per country, with a Central Secretariat in Geneva, Switzerland, that coordinates t

5、he system. ISO is a non-governmental organization: its members are not, as is the case in the United Nations system, delegations of national governments.

On the other hand, other members have their roots uniquely in the private sector, having been set up by national partnerships of industry associations. Therefore, ISO is able to act as a bridging orga
