Specification :

Standards developed by KATS are called Korean Industrial Standards ( KS) and are the Korean national standards. Generally, KS are voluntary, meaning the government does not require compliance with them in order to place a product in the Korean market. However, KS are frequently referenced in government regulations and technical specifications, and implemented by public agencies in procurement. For example, Korean government ministries currently reference about 19, 000 KS in over 106 types of laws and regulations.
