NTS Performs HERO Testing

Hazard of Electromagnetic Radiation to Ordnance (HERO) testing ensures the safety of 25mm rounds under high levels of radiation.

September 16, 2009, Calabasas, CA National Technical Systems Inc. (NASDAQ: NTSC) (NTS), is pleased to announce the addition of Hazard of Electromagnetic Radiation to Ordnance (HERO) testing to its wide array of capabilities.

NTS teams in Boxborough, MA and Camden, AR jointly developed the test procedure and method in response to a customer request for testing on two 25 mm rounds typically fired from an M242 cannon. One round contained a piston actuator detonator and the other contained an Electro-Explosive Device (EED) detonator.

HERO testing is to determine that the ordnance safety margins required are met when the unit under test is exposed to the high levels of electric fields required by MIL-STD-464. This requires that the test method measures the current induced into the unit’s bridgewire and compares the measurements to the pre-determined mean no-fire current (MNFC) of the bridgewire.

NTS investigated various methods and chose to utilize a system manufactured by Opsens of Quebec City to measure the current on the bridgewire. The NTS Test Procedure was based upon limits in MIL-STD-464, the Army’s TOP 1-2-511, and MIL-HDBK-240.

“We are pleased at the expansion of our offerings to include HERO, and look forward to expanding this capability to our other EMC laboratories” stated James Press, National EMC Director for NTS.
