Thunder Scientific's NVLAP Accreditation


Thunder Scientific Corporation is pleased to announce that for the effective dates June 22, 2022 through June 30, 2023, Thunder Scientifics’ calibration laboratory received renewed accreditation (Laboratory Code 200582-0) from the National Voluntary Laboratory Accreditation Program (NVLAP), administered by the National Institute of Standards and Technology (NIST) (What Is NVLAP?) (Directory of Accredited Laboratories).


Thunder Scientific is now NVLAP Accredited for field Calibrations

Thunder Scientific has added to its scope of accreditation, field calibration of all series 1200, 2500, and 2900 humidity generators. Holding true to Thunder Scientifics’ commitment to quality, all on-site calibrations are compliant to ISO/IEC 17025:2017 and ANSI/NCSL Z540-1-1994, Part 1 requirements.


Thunder has added field accreditation for the model 2900 humidity generator.

Thunder's Calibration Laboratory field support staff will travel to your location with traceable standards for dew-point inter-comparison, pressure calibration and temperature calibration of your Model 1200, 2500, or 2900 generator. Our field support staff will inspect and conduct all required maintenance on your humidity generator. Calibration reports include the NVLAP logo and laboratory code, “As Found” data, “As Left” data, and a concise statement of the method used.


Thunder's accredited field humidity uncertainties are the lowest commercially available. Our turn-around times are excellent and prices are very competitive.


Note: Due to the high demand of this service you will have to schedule your field calibration one to two months in advance, so call or email your sales representative as soon as possible to schedule your appointment.

NVLAP accreditation criteria are established in accordance with the U.S. Code of Federal Regulations (CFR, Title 15, Part 285), NVLAP Procedures and General Requirements, and encompass the requirements of ISO/IEC 17025:2017. Accreditation is granted following successful completion of a process which includes submission of an application and payment of fees by the laboratory, an on-site assessment, resolution of any nonconformities identified during the on-site assessment, participation in proficiency testing, and technical evaluation. The accreditation is formalized through issuance of a Certificate of Accreditation and Scope of Accreditation and publicized by announcement in various government and private media.


NVLAP provides an unbiased third-party evaluation and recognition of performance, as well as expert technical guidance to upgrade laboratory performance. NVLAP accreditation signifies that a laboratory has demonstrated that it operates in accordance with NVLAP management and technical requirements pertaining to quality systems; personnel; accommodation and environment; test and calibration methods; equipment; measurement traceability; sampling; handling of test and calibration items; and test and calibration reports.
