Expanding Lightning Capabilities

We are continuing to expand our test capabilities with the acquisition of an

additional lightning generator capable of reaching Level 5 pulse requirements

of DO-160 D/E/F Section 22 - Indirect Effects of Lightning. We are able to meet

requirements for the Boeing 737, 777, & 787 as well as those for the Airbus

A380 and A350. This testing is available at our Fullerton, CA and Boxborough, MA
sites and will be available in Plano, TX in late March, early April.
To discuss this type of testing, please contact Jim Press, National EMC Director,
at jim.press@ntscorp.com.

Real Time, Any Time, Any Where Access

At NTS we are committed to utilizing the most up to date technology to provide you with unsurpassed access to the information vital to your programs success. NTS LabInsight gives you program information, data, reports, status of procurement activities, and the ability to witness test programs or view data remotely in real time. Contact your local lab or Customer Service Director Jason Youmazzo at jasony@ntscorp.com to discuss how LabInsight can work for you.

MIL-STD-461 RS105 Generator - Coming Soon!
NTS Fullerton is currently installing a pulser and parallel plate antenna to meet the RS105 test requirement of MIL-STD-461E/F. RS105 simulates the electric field that results from a Nuclear Electro-Magnetic Pulse (EMP).

To discuss this type of testing, please contact Jim Press, National EMC Director, at jim.press@ntscorp.com. To request a quotation, visit our website to submit your program details on our quote request form.

AS9100 Standard Revision Moved Up
The AS9100 revision was originally scheduled to be released in 2009 after release of the revised ISO 9001 standard. In light of the fact that the ISO 9001 standard release date has been moved up to into 2008, the release of the new AS9100 standard may be moved up to as early as November 2008.

Though the exact wording is still being worked out, proposed changes include the clarification of existing elements, additions to existing elements or omissions. The most significant changes being evaluated are listed in detail in this complete article, written by Bob Parsons, Director of Aerospace Programs for our registration division, NQA, USA. He can be contacted at rparsons@nqa-usa.com or by calling the NQA, USA headquarters at  800-649-5289.

RS103 1-2GHz

• CE101: Now applicable for equipment used on surface ships.
• CS106: New addition similar to CS06 of MIL-STD 461A/B/C CS06, applicable to Surface Ship, and Submarine installations.
• CS109: Now only applicable for surface ship equipments that have an operating frequency of 100 kHz or less and have the sensitivity to read a signal at or below 1 µV.
• CS114: An additional low frequency sweep is now applicable for Surface Ships, and Submarine installations (77dBuA from 4kHz-1MHz). Test time will be impacted slightly due to additional calibration and common mode test on power lines, as well as multiple test equipment setups to complete the range.
• CS115: Only applicable for Surface Ship, and Submarine procurements when specified by the Procuring Activity.
• CS116: Now only one limit, which peaks at 10 Amps. Also, changed from applicable to limited applicability for Submarine installations
• RE101: If the emissions at any given frequency exceed the specified limit, the measurement distance shall be increased until the emissions fall below the limit. This distance shall be recorded for the test report. This is similar to MIL-STD 461D where 7cm and 50cm measurements were required. However, the actual passing measurement distance is undefined. Also, changed from applicable to limited applicability for Submarine installations
• RE102: The set up of the 104cm rod antenna has changed dramatically. The spacing off of the ground plane is now 120cm between the ground plane and center of the vertical 104cm receive rod. No bonding strap from the antenna base to the ground plane. The coaxial RF cable shield shall be bonded to the floor of the chamber though a barrel or elbow connector. The RF cable between the shield termination and connection the antenna shall be ferrite loaded providing 20 to 30 ohms at 20MHz.
• RE102: There has been a new limit added for surface ship installations to include below decks as well as above decks. This new below deck limit provides a 20dB relaxation.
• RS103: The sweep and step rates have been increased above 1GHz. For example, in MIL-STD 461E they were 1 GHz - 8 GHz 0.000667 fo/sec 0.001 fo and 8 GHz - 40 GHz 0.000333 fo/sec 0.0005 fo.  MIL-STD 461F requires 1 GHz - 40 GHz 0.00167 fo/sec 0.0025 fo. This change will cut test times above 1GHz in half. Also the TILE RS103 profile will need to be tailored above 1GHz specifically for Rev F.  
• RS103 requires measurement at the fundamental frequency i.e. need to remove harmonics from the measurement.
