SASO is the abbreviation of Saudi Arabian Standards Organization. In fact, many SASO standards are based on the safety standards of relevant international organizations such as the International Electrotechnical Commission (IEC). Like many other countries, Saudi Arabia has added some unique items to the standards based on its own civil and industrial voltages, geographical and climatic environment, ethnic and religious customs, etc. In order to protect consumers, SASO standards are not only applicable to products imported from abroad, but also to products produced in Saudi Arabia.
