What is CNS Standards ?

CNS Standard is abbreviation of Chinese National Standard, the National Standards of the Republic of China (Taiwan) ;
They are administered by the Bureau of Standards, Metrology and Inspection of the Ministry of Economic Affairs.

The English versions CNS standards were translated directly from the openly-published Chinese CNS standard , in case of any divergence of interpretation, the Chinese versions CNS standards text shall prevail.

CNS standards are divided into 26 numbered categories, Detail see bellow:
