GR-1089-CORE

GR-1089-CORE, Electromagnetic Compatibility and Electrical Safety - Generic Criteria for Network Telecommunications Equipment. Together with GR-63-CORE, these two documents make up what's known as the "NEBS Criteria".

GR-1089-CORE details Electromagnetic Compatibility (EMC) and Safety requirements, including:

Electrostatic Discharge (ESD)
Electromagnetic Interference (EMI)
Radiated Emissions (Electric Fields)
Radiated Emissions (Magnetic Fields)
Conducted Emission (AC Power Leads - Voltage)
Conducted Emission (AC and DC Power and Signal Leads - Current)
Conducted Emission (Analog Voiceband Leads)
Lightning and AC Power Fault
Steady-State Power Induction
DC Potential Difference
Electrical Safety
Corrosion
Bonding and Grounding

NTS has all the required expertise and facilities to perform all over-voltage, EMC, lightning, safety, and other requirements as specified in GR-1089. The NTS facilities contain six 3m/10ft chambers, four 10m/33ft Open Area Test Sites (OATS), and two 10m/33ft chambers. The NTS facilities have the standard European Mark (CE) testing experience and equipment to meet the electrostatic discharge (ESD) and electric fast transient (EFT) of Section 2 of GR-1089. Most CE Mark test labs have no experience in performing EMC and lightning NEBS testing and their results will not be accepted by the RBOCs (Regional Bell Operating Companies). NTS has performed many re-tests after a CE-Mark test lab performed emission, immunity, and surge testing per the European requirement, instead of performing these specialized tests per the requirements of GR-1089. The lack of experience and equipment is the primary reason for Verizon establishing the ITL program to assure that these inexperienced laboratories were testing to the NEBS requirements.

NTS has laboratories capable of meeting all levels of lightning and power-cross as defined in Section 4 of GR-1089. This test can be destructive and NTS provides an effective value-added service to assure the testing is performed in a cost effective manner to minimize the time spent replacing transient surge protectors between surges and power applications.

NTS is a Nationally Recognized Test Laboratory (NRTL) which is an OSHA approval authorizing NTS to determine the safety of various products and telecommunication gear. As such, NTS is overly qualified to test and inspect gear in accordance with Sections 7 & 9 of GR-1089. The NRTL approvals places NTS with a selected few laboratories in the US which are approved by the US Government to certify the safety of equipment for use by craftsman or the general public.
