| Contamination of the environment by dioxins,
etc. is a serious 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 very 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, 2001 in order to enhance
the reliability of certified measurement data of micro existent substances
such as dioxins.
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 (Note 1) and be accredited as an "accredited
specified measurement Laboratory "(the effective date is April 1,
2002.).
The scheme of the accreditation is as shown below. |

We are distributing hard copy of the MLAP
symbol to the laboratories which plan to apply for the MLAP. If
you want to be sent one by mail, please contact us.

Prescribing in the measurement law
Use of the MLAP symbol is prescribed in
the Measurement Law. Everyone should follow these provisions.
|

Reference) Distribution of
the measurement laboratories symbol
The measurement laboratories symbol can
be downloaded from Ministry
of Economy, Trade and Industry (METI),Measurement and Intellectual
Infrastructure Division . We are also distributing a hard copy
of the symbol to the laboratories. If you want to be sent one
by mail, please contact us. When measurement laboratories issue a
certification with the symbol, they should submit the notification
to the local government about the alteration of their provisions.

Business Category of MLAP
|
|
|
The business category of MLAP is set as shown below so
far.
- Business of measurement certification for concentration
of dioxins in air (Note 2)
- Business of measurement certification for concentration
of dioxins in water or soils (Note 2)
- Others
(Note 1) When a designated accreditation
body is designated, an application can be made to the designated
accreditation body as well.
(Note 2) As for the business for measurement
certification above 1 and 2 , unless a laboratory is granted accreditation
as an accredited specified measurement laboratory and registered by
a local government, it will not be able to do business for measurement
certification from April 1, 2002. |
