RS105 Testing Determines EMP Susceptibility of Military and Commercial Electronics

Recently, MET Labs performed High Altitude (or Nuclear) Electromagnetic Pulse (HEMP or NEMP) susceptibility testing of U.S. Navy vendor electronics at an outdoor test area in Maryland. The test method used was RS105 from MIL-STD-461.   RS105 addresses the risk of radiated exposure to an EMP event. (CS116 is the MIL-STD-461 test method that addresses conducted... Read More

UK & Australian Companies May Be Exempt from ITAR Licensing for MIL-STD Testing

Foreign manufacturers of products that require U.S. Military Standard (MIL-STD) testing need to comply with the Arms Export Control Act and the International Traffic in Arms Regulations (ITAR). Obtaining ITAR licensing and development of technical agreements can be a lengthy process.  Fortunately, clients in the United Kingdom and Australia can simplify the process and bypass... Read More

Environmental Testing – Like HALT – Improves Product Reliability & Ruggedness

Environmental testing has nothing to do with an evaluation of the earth’s environment.   Not the environmental testing we’re writing about here anyway. Also known as environmental simulation, environmental testing involves putting your electronic product through environmental extremes and then determining what hardware failures occur.   This process is crucial for pinpointing design flaws for ensuring the...

MIL-STD-461 for Military EMC & GR-1089-CORE for NEBS Telecom EMC Share Some Requirements

The electromagnetic compatibility (EMC) requirements for telecom and military equipment are considered among the most difficult to meet for any industry.  Not many electronics manufacturers conduct testing for both requirements, but it happens occasionally.  For those who do, it’s an advantage to pursue both at the same time, as there is some overlap.  Following is...

MIL-STD-461 EMC Testing FAQs for Military and Marketing Requirements

MIL-STD-461 is the standard that defines the test limits, test levels, and test procedure for various electromagnetic phenomena for electronic equipment used by the U.S. Army, Navy, and Air Force on all platforms (ground, sea, and air).  MIL-STD-461F is the latest version.  Following are answers to common questions about this often-utilized military EMC standard. Where... Read More

Shielded Bulkhead Connectors Mitigate Ambient Emissions for Military & Avionic EMC Testing

Most Military/Avionic EMC test programs include radiated emissions testing.  This is the test method where the unintentional emissions which    radiate from a piece of electronic equipment under test are measured with an antenna and spectrum analyzer and plotted against the required limit.  One issue which must always be dealt with during radiated emissions and...
