About MLAP

用日语表示

Contamination of the environment by dioxins，etc.is aserious issue in our life.But it is very difficult to measure the concentration of substances like dioxins in our environment because the level of concentration is usually low（ppt level）。To ensure accurate measurement of the micro existent substances like dioxins，the Measurement Law was amended in June 2001，and thereby Specified Measurement Laboratory Accreditation Program（MLAP）was introduced。

What's Specified Measurement Laboratory Accreditation Program（MLAP）？

Specified Measurement Laboratory Accreditation Program（MLAP）is an accreditation system that was newly introduced with the amendment of Measurement Law of Japan in June，2001in order to enhance the reliability of certified measurement data of micro existent substances such asdioxins。
By the introduction of MLAP，a laboratory doing business for certifying measurement data of dioxins，etc.can apply for MLAP accreditation to National Institute of Evaluation and Technology（Note1）and be accredited asan“accredited specified measurement Laboratory”（the effective date is April1,2002。
The scheme of the accreditation is as shown below。
