NEBS Requirements

NEBS (Network Equipment Building Systems) requires products to be evaluated in extreme environments and phenomena. The key NEBS tests include:

  • Humidity
  • Vibration
  • Fire
  • Surge Power Fault
  • Temperature
  • Altitude
  • Lightning
  • Earthquake
  • Airborne Contaminants
  • Acoustic 

Four in-house labs at each MET NEBS facility afford flexible scheduling and complete testing to NEBS requirements:

  • EMC/EMI – GR-1089-CORE, Sections 2, 3
  • Environmental Simulation – GR-63-CORE, GR-487-CORE, GR-950-CORE, GR-3108-CORE, GR-49-CORE, GR-4228-CORE
  • Telecom – GR-1089-CORE, Sections 4-10
  • Product Safety – US and Canadian Product Safety Certification

Additional requirements include an NRTL evaluation for electrical product safety.  MET provides the NRTL certification for electrical product safety which is referenced in NEBS and OSHA requirements. MET was the first licensed NRTL in the country, and continues to be top-ranked.

MET has developed a keen understanding of the complexity of NEBS requirements. At MET, each test program is customized, based on factors such as equipment type, installation conditions, and location.

These factors must be properly addressed prior to testing in order to avoid costly and time-consuming re-testing. MET stays current on changes to the requirements or applicability of the various RBOCs (Regional Bell Operating Companies), so we can provide the most up-to-date service available.


MET sets the standards for customer service by which other labs are measured.

MET employs full-time project coordinators who serve as customer liaisons to assure the smoothest possible test program. Our NEBS coordinators are knowledgeable in NEBS requirements and MET staff, facilities, and procedures.

The NEBS coordinators work together as a team with the project engineers and with customers. The customer is always able to interface directly with MET engineers and NEBS coordinators. The customer is always welcome to send a representative to witness the testing.

MET has several customer lounges, and provides fax, copy, and internet services. Additionally, our proprietary METrak Online service gives the customer the tools to track testing progress in real time, online, from any internet-ready location.

If anomalies are discovered in the test results, the customer will be updated immediately. MET's experienced professionals will quickly assist in attaining reasonable, cost-effective solutions. Without delay, we can re-test to evaluate the solutions. MET offers the most flexible test schedule in the testing industry. We can work every day of the year, at every hour of the day.

MET can save you time and money by creating a custom test program which integrates domestic and international regulatory compliance for NEBS. For more information, e-mail us.


MET's designation as a Verizon-certified Independent Test Laboratory (ITL) for NEBS highlights the recognition of MET certification by all of the nation's RBOCs. MET has earned this recognition by working closely with the RBOCs to apply NEBS standards to their requirements. MET also works closely with AT&T and their NEBS standards.

By working so closely with the RBOCs, MET has developed a report format that provides a level of detail which exceeds their expectations. This reduces the need for further scrutiny and accelerates the evaluation time of the purchasers. As an independent third party and an NRTL, MET delivers reports that provide credibility.

By working closely with manufacturers, holding regular, timely NEBS seminars and workshops on both coasts, and providing consultation services at the manufacturers' facilities, MET keeps the process as surprise-free as possible.

Products get to the market first when tested by MET.
