About ISO Standard
ISO, the International Organization for Standardization, is an independent, non-governmental organization, the members of which are the standards organisation of the 163 member countries. It is the world's largest developer of voluntary international standards and facilitates world trade by providing common standards between nations. Nearly twenty thousand standards have been set covering everything from manufactured products and technology to food safety, agriculture and healthcare.
Use of the standards ensures that products and services are safe, reliable and of good quality. The standards help businesses increase productivity while minimising errors and waste. By enabling products from different markets to be directly compared, they facilitate companies in entering new markets and assist in the development of global trade on a fair basis. The standards also serve to safeguard consumers and the end-users of products and services, ensuring that certified products conform to the minimum standards set internationally.

About CE Standard
The CE mark, or formerly EC mark, is a mandatory conformity marking for certain products sold within the European Economic Area (EEA) since 1985. The CE marking is also found on products sold outside the EEA that are manufactured in, or designed to be sold in, the EEA. This makes the CE marking recognizable worldwide even to people who are not familiar with the European Economic Area. It is in that sense similar to the FCC Declaration of Conformity used on certain electronic devices sold in the United States.
It consists of the CE logo and, if applicable, the four digit identification number of the notified body involved in the conformity assessment procedure.
The CE marking is the manufacturer's declaration that the product meets the requirements of the applicable EC directives.
The actual words signified by "CE" have been disputed. It is often taken to be an abbreviation of Conformité Européenne, meaning "European Conformity". However, "CE" originally stood for "Communauté Européenne", French for "European Community". In former German legislation, the CE marking was called "EG-Zeichen" meaning "European Community mark". The CE marking is a symbol of free marketability in the European Economic Area.
