NVLAP — National Voluntary Laboratory Accreditation Program
Administered by the National Institute of Standards and Technology (NIST) under the U.S. Department of Commerce. NVLAP is the recognized accreditation program for asbestos fiber analysis in bulk building materials and is required for many federal and state asbestos abatement projects.
Bulk Asbestos Analysis — NVLAP Lab Code 101793-0
NVLAP accreditation is the gold-standard credential for asbestos bulk material analysis in the United States. Issued under ISO/IEC 17025:2017, NVLAP accreditation demonstrates that a laboratory has met the technical competence requirements established by NIST through proficiency testing, documented quality systems, and on-site assessment.
Most state asbestos programs and federal renovation/demolition projects under EPA AHERA and NESHAP require analysis by an NVLAP-accredited laboratory. AGT Labs has held continuous NVLAP accreditation for asbestos fiber analysis under Lab Code 101793-0.
What This Means For You
If you're an AHERA-certified inspector, demolition contractor, school district, or property owner — NVLAP is the credential federal and most state regulators specifically require for asbestos PLM bulk analysis. Reports issued under Lab Code 101793-0 are accepted nationwide for AHERA, NESHAP, OSHA 1926.1101, and HUD lead/asbestos projects.

Both methods are performed by Polarized Light Microscopy (PLM) with dispersion staining, the EPA-recognized technique for identifying and quantifying asbestos in solid building materials. Used for pre-renovation surveys, AHERA inspections, and state-mandated abatement clearance work.
PJLA / DoD-ELAP — Defense Environmental Laboratory Accreditation
Required to perform environmental testing for the U.S. Department of Defense and U.S. Department of Energy. AGT Labs is one of a limited number of laboratories nationwide accredited under DoD-ELAP for asbestos analysis on military installations.
Environmental Testing — DoD-ELAP Asbestos Scope
The Department of Defense Environmental Laboratory Accreditation Program (DoD-ELAP) is administered by accredited bodies like Perry Johnson Laboratory Accreditation, Inc. (PJLA), and is mandatory for any laboratory performing environmental analysis on U.S. military installations or DOE-managed sites. DoD-ELAP labs operate under the DoD/DOE Quality Systems Manual (QSM) Version 5.4, which adds defense-specific quality controls on top of standard ISO/IEC 17025 requirements.
This accreditation makes AGT Labs eligible for projects involving BRAC (Base Realignment and Closure) remediation, military housing renovation, federal facility compliance under UFC 3-490-04A, and DOE site environmental management.
What This Means For You
If you're a federal contractor, A&E firm, or environmental consultant working on a DoD installation, military housing project, or DOE site — your asbestos sample data must come from a DoD-ELAP accredited lab. Many commercial labs hold ISO 17025 alone but cannot perform DoD work. We can.

What Accreditation Actually Means For Your Project
Anyone can call themselves a "lab." Accreditation is what separates a private testing operation from one whose results are accepted by OSHA, the EPA, the courts, and the U.S. military.
Defensible In Court
ISO/IEC 17025:2017 accredited results carry evidentiary weight in OSHA enforcement actions, workers' compensation claims, indoor air quality litigation, and asbestos liability cases. Non-accredited results often don't.
Continuous Oversight
Accreditation isn't a one-time stamp. It requires ongoing on-site assessments, blind proficiency testing rounds, internal audits, and method validations — every year, on every accredited method.
International Recognition
NVLAP, AIHA-LAP, and PJLA are all signatories to the ILAC Mutual Recognition Arrangement. Our reports are accepted in over 100 countries — useful for global manufacturers, multinational employers, and export compliance.
Federal & Defense Eligible
DoD-ELAP accreditation makes our asbestos work eligible for U.S. military installations, BRAC remediation projects, and DOE managed sites — a credential most commercial labs don't carry.
Method Traceability
Every accredited method is traceable to its published reference (NIOSH, OSHA, EPA, AHERA). Your final report cites the exact method version run, so your consultants and regulators know exactly what was measured and how.
Multiple Independent Bodies
Three different accreditation bodies (NVLAP, AIHA-LAP, PJLA) plus two state regulators — each independently auditing different aspects of our quality system. No single point of failure in oversight.
What Holds The Accreditation Up
An accreditation certificate is the visible proof. The real work happens daily — in personnel competence, proficiency testing, internal QC, and chain-of-custody discipline. ISO/IEC 17025:2017 doesn't just require a quality manual; it requires that each of these be demonstrably operating on every sample we run.
Personnel Competence
ISO 17025 §6.2 requires documented competence for every analyst on every accredited method. Our staff competence file includes:
- Initial demonstration of capability (IDOC) on each method before unsupervised work
- Continued demonstration of capability via blind QC samples
- NIOSH 582 training for all PCM (asbestos air) analysts
- NVLAP-required training for PLM bulk asbestos analysts
- Documented role-specific training for microbiology, IC, GC/MS, and ICP analysts
Proficiency Testing (PT)
Each accredited method is verified by blind, third-party-administered proficiency testing rounds — every year, on every method, without exception:
- AIHA-PAT rounds for Industrial Hygiene chemistry methods
- AIHA-EMPAT rounds for Environmental Microbiology methods
- NIST NVLAP proficiency rounds for asbestos PLM bulk analysis
- DoD/DOE QSM v5.4 PT requirements for ELAP-scope methods
- Failed-round corrective action documented and audited per ISO 17025 §7.7
Internal Quality Controls
Every analytical batch carries the QC controls required to validate the result before it leaves the lab — not a sampling, every run:
- Method blanks to verify the system is contamination-free
- Laboratory Control Samples (LCS) to verify accuracy at known concentrations
- Matrix spikes & matrix spike duplicates (MS/MSD) for recovery and precision
- Calibration verification standards bracketing every analytical run
- Initial & continuing calibrations meeting method-specific %R and RSD criteria
Chain of Custody & Traceability
Defensible data starts before the sample arrives. Our COC and sample-handling protocol satisfies OSHA, EPA, AHERA, and DoD evidentiary requirements:
- Unique laboratory ID assigned at receipt; original COC document retained
- Sample condition, temperature, and integrity verified and recorded
- Every transfer of custody (receipt → prep → analysis → archive) signed and dated
- Reference standards and reagents traceable to NIST or certified suppliers
- Sample retention and disposal logged per regulatory and client retention rules
How To Independently Verify Each Accreditation

What is ISO/IEC 17025:2017 and why does it matter?
ISO/IEC 17025:2017 is the international standard for the technical competence of testing and calibration laboratories. Accreditation under this standard is granted only after rigorous, on-site assessment of a lab's quality management system, equipment, methods, personnel competence, and proficiency testing performance.
AGT Labs holds ISO/IEC 17025:2017 accreditation under three independent bodies — AIHA-LAP, NVLAP, and PJLA.
How do I independently verify all of these accreditations?
All five accreditations are publicly verifiable:
• NVLAP Lab Code 101793-0 → nist.gov/nvlap
• AIHA-LAP Lab ID LAP-101470 → aihaaccreditedlabs.org
• PJLA Accreditation No. 71390-1 → pjlabs.com
• Texas DSHS Asbestos License 300529 → dshs.texas.gov
• Texas TDLR Mold License LAB1070 → tdlr.texas.gov
What does DoD-ELAP accreditation actually cover?
DoD-ELAP (U.S. Department of Defense Environmental Laboratory Accreditation Program) authorizes a lab to perform environmental testing on military installations, BRAC remediation projects, and Department of Energy sites.
AGT Labs holds PJLA DoD-ELAP accreditation No. 71390-1, valid through February 21, 2027, covering asbestos in solid materials by EPA 600/R-93/116 (PLM) and asbestos in air by NIOSH 7400 (PCM), under DoD/DOE QSM v5.4.
What is the difference between NVLAP and AIHA-LAP?
Both are ISO/IEC 17025:2017 accreditation programs, but they cover different scopes.
NVLAP (administered by NIST under the U.S. Department of Commerce) is the recognized accreditation for asbestos fiber analysis in bulk building materials. AIHA-LAP (administered by AIHA Laboratory Accreditation Programs, LLC) accredits laboratories for industrial hygiene chemistry methods (IHLAP) and environmental microbiology (EMLAP).
AGT Labs holds both — NVLAP Lab Code 101793-0 and AIHA-LAP Lab ID LAP-101470.
Are your reports accepted for OSHA enforcement & legal cases?
Yes. ISO/IEC 17025:2017 accredited results are accepted by OSHA, EPA, the Department of Defense, state regulatory agencies, and courts of law as defensible analytical data.
Our accreditations are recognized internationally through the ILAC Mutual Recognition Arrangement (ILAC-MRA), meaning our reports are accepted by signatory countries worldwide.
How many analytical methods does AGT Labs hold accreditation for?
AGT Labs maintains AIHA-LAP IHLAP accreditation for 117 individual industrial hygiene method entries spanning 12 analytical platforms — including GC/FID, GC/MS, GC/ECD, HPLC, Ion Chromatography, ICP/AES, XRD, CVAA, gravimetric, UV/VIS, and PCM.
Our scope is among the broadest IHLAP scopes among U.S. industrial hygiene testing laboratories. The full list of accredited methods is published in the AIHA-LAP section above.
How often are accreditations renewed?
NVLAP renews annually. AIHA-LAP operates on a 2-year cycle with annual surveillance. PJLA DoD-ELAP runs a continuous accreditation cycle with periodic on-site assessments. Texas DSHS asbestos licenses run 2 years; Texas TDLR mold licenses run 2 years.
Between renewals, accredited labs are continuously evaluated through proficiency testing rounds, internal audits, and method-by-method quality control performance.
