Date Posted: 1-28-2017
On January 24, 2017, TNI announced the recognition of the three Non-Governmental Accreditation Bodies listed below:
ANSI-ASQ National Accreditation Board
American Association for Laboratory Accreditation (A2LA)
Perry Johnson Laboratory Accreditation, Inc. (PJLA)
These organizations have been recognized to "assess and accredit laboratories to the applicable version of Volume 1, Management and Technical Requirements for Laboratories Performing Environmental Analysis."
As stated in the TNI website:
If your laboratory is located within a state with a NELAP-recognized Accreditation Body, you must go to that state for accreditation.
If your laboratory is in another state or country, you can choose to apply to any NELAP AB or a NGAB. Be careful of these facts:
- Some states only offer accreditation in some areas, e.g., only drinking water.
- Some states will not accredit out-of-state laboratories.
- Some states will not accept accreditations from NGABs.
