Vincent Greb, founder of EMC Integrity, added, "EMCI has a great reputation in the local market that, when combined with NTS' respected national brand, will allow NTS Longmont to enter its next phase of growth. Our folks are very excited to be part of the NTS team, and we look forward to further investing in our local capabilities to serve our clients and all of their EMI / EMC and other testing needs."

EMC Integrity Receives CBTL Cert

It's official.  EMCI is now a CBTL for medical EMC testing!

EMCI is now one of the few CB Testing Laboratories (CBTLs) for electromagnetic compatibility in the United States.   We have long been a leader of EMC testing for medical products for CE, FDA and JFDA compliance.  Becoming a CBTL opens EMCI up to the prospect of doing CB Scheme EMC testing for medical products for world-wide compliance.  Our scope includes 2nd, 3rd and 4th editions of IEC 60601-1-2.

The CB Scheme is an internationally accepted approach to compliance for electrical and electronic equipment.  It is operated by the IEC System for Conformity Testing and Certification of Electrotechnical Equipment and Components (IECEE).  While it is well-established for product safety, the EMC part of the CB Scheme is only recently gaining traction, particularly for medical equipment.  The concept is that a product can be tested once, and the CB reports (one for EMC and one for product safety) will allow sale of the product into any CB member country, provided all the national deviations are observed.  Click here to view our certificate.

EMCI Accredited for MIL-STD-461F Testing

In response to increasing demand, EMC Integrity has recently expanded its scope of accreditation to include 12 tests required by MIL-STD-461F.  Among the more notable of these are CE101, CE102, RE102 and RS103.  Historically, the MIL-STD and aerospace worlds have not required accredited testing, as these tests were often done under the supervision of a client witness.  However, we are now seening fewer client-witnessed tests and more frequent requests for accredited MIL-STD testing.  In June, we completed the automation on our CS114 testing, and we continue to focus our efforts in improving our level of automation for MIL-STD testing overall.  This will not only improve the repeatability and reproducibility of our MIL-STD testing, but also dramatically improves our already high level of test documentation.

EMCI has been accredited by NVLAP (NVLAP Lab Code 200737) since 2006.  Initially done to support our commercial testing, our scope has consistently expanded to include testing for Taiwan, Korea, Japan and most recently, Vietnam.  The addition of the MIL-STD-461F accreditation is just the next step in a continuing effort to enhance the range of accredited services we can provide.

EMCI Expands Capability to Intentional Transmitters

EMC Integrity is pleased to announce that it is finally official:  we're now testing intentional transmitters.  Our in-house test capability includes FCC (Federal Communication Commission for the US), IC (Industry Canada for Canada) and CE testing (Conformite European for the European Union).  However, EMCI also offers world-wide access through our partner-lab relationship with Nemko.

It seems nearly everyone is using the 2.4 GHz band these days, but requirements can vary depending on whether or not a product is a frequency hopping spread spectrum (FHSS) device, Bluetooth Legacy, Bluetooth Low Energy, Zigbee, etc.  EMCI has direct access to decades of intentional transmitter expertise and is happy to assist and educate our clients.

Contact us and we will take the time to meet with you, discuss your project requirements, give your a tour of our facilities, as we offer first-hand access to our expertise.  If you would like our intentional transmitter expert to visit your facility and meet with your staff, let us know and we'll make an appointment.  Whether it's 2.4 GHz, 5.8 GHz, 902 to 928 MHz or a different band entirely, EMCI will be happy to assist.

EN 61326-1:  2013 Now Mandatory

EN 61326-1, the harmonized standard for test, measurement and laboratory equipment, has been updated.  The new version is EN 61326-1:  2013.  Many people who qualify their products under the generic standards aren't even aware of the existence of this standard, but EN 61326-1 is the product family standard for electrical equipment for measurement, control and laboratory use.  In other words, this standard defines the EMC emissions and immunity requirements for compliance with these product types for shipment into the European Union (EU).  The 2013 version was harmonized (i.e., published in the Official Journal of the EU) in 2014, and it became mandatory on August 15th of 2015.  The implication is that on or after that date, data, DoCs, etc. referencing the 2006 version will no longer be valid.

Recall that the hierarchy for EU standards is product specific, then product family and then generic.  If a product specific standard exists for your product, you should test to it.  If not, you should qualify your product by testing to a product family standard.  If neither product specific nor product family standards exist for your product, you should qualify your product by testing to the generic standards.

For emission requirements, EN 61326-1 simply references CISPR 11/EN 55011 (the product family emissions standard for industrial, scientific and medical equipment).  However, for immunity, it defines three different types of environments:  basic, industrial and controlled electromagnetic.  In addition, Annex A defines a limited subset of immunity requirements for portable test and measurement equipment which is battery powered.  (An example of a product type covered under Annex A would be a battery-powered digital multi-meter.)

4th Edition of IEC 60601-1-2 Published

In February of this year, IEC 60601-1-2, 4th Edition (2014-02) was published.  Although this document has yet to be harmonized (i.e., recognized by the EU as an EN document), it is anticipated that when this happens, the new requirements will become effective sometime in 2017.  While the emission standards remain essentially unchanged, there have been some dramatic changes made to the immunity requirements.

Two areas which will impact most designs are electrostatic discharge and radiated RF immunity.  Both requirements now have significantly higher test levels.  For RF immunity, higher levels are coupled with new modulation schemes which could make compliance for analog circuitry considerabley more challenging.  ESD test levels have also been increased from 6 kV contact and 8 kV air to 8 kV contact and 15 kV air, respectively.  In addition, it is possible that ESD may now be applied to connector pins on patient-connected ports.  In the event this testing is applicable, the test level would be +/-15 kV!  Not only does this break new ground for commercial ESD testing, it does so at what could be a very destructive test level.

EMC Integrity has the equipment to perform testing to the newer, more stringent levels.  We can also craft a test matrix which will cover both 3rd and 4th editions, thus saving both time and money.  In the event of a product failure, we have relationships with qualified design consultants who have the design expertise to help clients meet these requirements with manufacturable, cost-effective solutions.

We will soon be publishing a white paper which outlines the new medical requirements.  If you need information sooner, please contact EMCI and we'll be happy to walk you through the new EMC requirements for medical devices and how these might impact your product design.
