DNDO Accepted Laboratories for the GRaDER Program

The Countering Weapons of Mass Destruction (CWMD) Office was established in December 2017 by consolidating primarily the Domestic Nuclear Detection Office, a majority of the Office of Health Affairs, as well as other DHS elements.

For current information related to CWMD, please visit the following:

The Domestic Nuclear Detection Office (DNDO) has developed an interim laboratory acceptance process for the Graduated Rad/Nuc Detector Evaluation and Reporting (GRaDER SM) Program that enables participating laboratories to begin the American National Standards Institute (ANSI) Institute of Electrical and Electronic Engineers (IEEE) N42 standards test process while awaiting National Voluntary Laboratory Accreditation Program (NVLAP) accreditation. The laboratory must have already submitted a NVLAP application for accreditation. The laboratory then provides a Self-declaration of Conformity packet to DNDO, indicating conformity with the National Institute of Standards and Technology (NIST) Handbooks 150 and 150-23-2007 (DRAFT), and ISO/IEC 17025:2005.

The standards and scope for which the laboratory will offer accredited testing services must be identified. After careful consideration and clarification, DNDO issues a temporary Letter of Acceptance to the Laboratory. The laboratory's acceptance is limited to one year or upon NVLAP accreditation for the stated scope of selected ANSI/IEEE N42-series consensus standards, whichever comes first. The DNDO Letter of Acceptance stipulates conditions under which the laboratory must operate and report in order to participate as a GRaDER Program supporting laboratory.

Equipment manufacturers should schedule their equipment for testing with the DNDO accepted or NVLAP accredited laboratories. Manufacturers must direct the laboratories to provide the test results to DNDO for evaluation in order to be considered by the GRaDER Program. Testing is voluntary and is at the manufacturer's expense. Additional information for manufacturer participation is available.

Participating Laboratories

Pacific Northwest National Laboratory (PNNL)

DNDO accepted a Self-declaration of Conformity from the Instrument Testing Laboratory (ITL) at Pacific Northwest National Laboratory (PNNL) on May 21, 2010. The scope of acceptance encompasses PNNL’s application for NVLAP accreditation, including the American National Standards Institute (ANSI) Institute of Electrical and Electronic Engineers (IEEE) consensus standards ANSI N42.32, N42.33, and N42.34 of 2006. PNNL is teamed with Northwest EMC Laboratory in Hillsboro, OR, for satisfaction of the electromagnetic compatibility (EMC) requirements. Northwest EMC is separately NVLAP accredited to perform EMC testing.

Future Participants

No other government or commercial laboratories have self-declared conformity to the NVLAP requirements.

NVLAP Accredited Laboratories

The National Institute of Standards and Technology (NIST) maintains a list of accredited laboratories for NVLAP.

This page will be updated as new laboratory participants are accepted by DNDO.
