European (CE mark) testing requirements for 2.4 GHz devices have changed greatly with the introduction of EN300 328 v1.8.1 and v1.9.1. New, unique measurement techniques have been added for FHSS equipment. The standard has also been adapted to recognize
technologies using MIMO such as WLAN and LTE. Additionally, the parameters of spurious emissions testing has changed from a constant resolution bandwidth to resolution bandwidths that vary by measurement frequency. The changes can affect the rating of
harmonics when measuring above 1 GHz.

High Intensity Radiated Field (HIRF) facilities at CKC are up, running and booking fast! HIRF testing is a significant expansion of our testing capabilities for the aerospace industry. Field strength levels of 3,000V/m (Cat. G), per DO-160 Section 20
for mode stirred and mode tuned procedures, can be reached in our copper-lined 10′ x 18′ x 8′ reverberation room. Levels are based on test volume uniform field dimensions of 4′(w) x 10′(l) x 3′(h), or smaller. For some smaller, highly reflective EUTs,
test levels of 7,200V/m are possible. CKC’s HIRF testing system is automated by Nexio’s EMC Automation Control software, creating an industry leading level of efficiency and accuracy.

For the first time in the history of the Telecommunications Certification Body (TCB) program, the TCB Exclusions List is empty. This means that all transmitter certification applications can now be processed by a TCB (like CKC Certification Services),
unless either the TCB or the applicant so choose to submit directly to the FCC. However, this does means that TCBs will be held strictly accountable to following the “Permit But Ask” (PBA) procedures. The PBA List consists of three different types of
- Pre-authorization required (implantable transmitters)
- FCC review/sample may be required (e.g. DFS testing, Boosters, etc.)
- Devices in specific categories requiring specific guidance.
Applicants must provide to the TCB any prior FCC PBA details and correspondence (including PBAs obtained by the test laboratory) in order to properly process the application. Devices subject to PBA rules require FCC intervention. This means in many
cases that the TCB reviews the majority of the application materials and then the FCC reviews on the “special cases” part of the application. The benefit to applicants is that while certain transmitters, such as those under PBA rules, may take longer
to certify than other transmitters being approved through TCBs, the change generally means faster certifications for transmitters previously mandated to be certified directly by the FCC.

In February of this year, the European Union published a new version of the law known as the EMC Directive. The new Directive 2014/30/EU will replace the previous version, 2004/108/EC. Highlights of new legislation include:
- Expansion of EMC requirements to used equipment, being imported from outside the EU.
- The directive applies to all forms of selling, including “distance selling.”
- All “economic operators” i.e. anyone involved with placing a device on the EU market has the responsibility to ensure that the device meets the requirements of the EMC Directive.
- Because of the above requirement, every importer needs to clearly post their contact information on the device. Exceptions are allowed if the device is too small for such placement or if the importer has to open the packaging to mark the device.
- Although not changed, the definition and purpose of standards harmonized under the EMC directive have been clarified. Simply stated, testing to harmonized EMC standards is used by manufacturers to demonstrate conformity with the essential requirements
of the directive. In other words, the technical standards and their purpose under the Directive remain mostly unchanged.
- A single declaration of conformity (DoC) or a unified dossier of individual DoCs should be used to demonstrate conformity with all applicable directives.
- Member states have been instructed to set forth penalties for the infringement of the provisions of the EMC Directive. Such penalties should be effective, proportionate and dissuasive. This is indicative of a world-wide trend by many market surveillance

The latest version of EN61326-1 was published in July of 2013 and will become the only active version of EN61326-1 in August of 2015. As with previous versions, EN61326-1:2013 contains EMC requirements which apply to electrical equipment for measurement,
control and laboratory use. The scope also includes accessories that are intended to be used with the aforementioned equipment. In addition, the 2013 version clarifies that it applies to equipment intended for use in both industrial and non-industrial
locations. As compared with the 2006 or earlier versions of EN61326-1, the 2013 edition contains a number of significant changes. Typically, these changes do require new testing for any product which is still actively marketed in the European Union. In
such cases, CKC recommends a thorough review of the test reports for these products. These reviews, known as ‘gap analysis,’ can be performed as a service by CKC, regardless of what laboratory performed the original testing. Once gap analysis is performed,
CKC will provide you with a detailed list of recommended actions, including a quotation for testing and report generation. The following is a list of changes in the testing requirements listed in the 2013 version versus the 2006 version.
Radiated Emissions and AC Conducted Emissions – CISPR 11:2009 is now the reference standard instead of CISPR 11:2003. Mains terminal and radiated disturbance limit lines were added for Group 1, class A equipment rated > 20kVA. The
Group 2, class A mains terminal disturbance limit line has changed for equipment <=75kVA. The Group 2, class A mains terminal disturbance limit line has been added for equipment rated >75kVA. There is now a 3m radiated disturbance limit line for
use when allowed. The Group 2, class A radiated disturbance limits below 30MHz has changed to a magnetic field. The Group 2, class A radiated disturbance limit line was added for frequencies above 1GHz.
Electro-Static Discharge (ESD) – the 2008 version of IEC 61000-4-2 is called out instead of the 2001 version. The basic EMC environment calls for an 8 kV air discharge instead of a 4 kV. Also, the rise time range changed from (.7 to 1ns)
to (.6 to 1ns). There were other changes in the calibration procedures, the distance from the EUT to the lab wall and the isolation distance of the EUT from the test table or floor.
Radiated Immunity – IEC 61000-4-3:2010 is now referenced instead of IEC 61000-4-3:2002. In addition to the previous requirement that frequency dwell times should be greater than or equal to the time necessary for the EUT to be exercised
and respond, a minimum dwell time of .5 seconds is now in place. Additionally, the “rate of sweep” requirement has been removed and the non-conducting support for floor standing equipment can now be in the range of .05 m to .15 m high, instead of exactly
.10 m high.
Electrical Fast Transient Burst (EFTB) – IEC 61000-4-4:2006 with Cor. 2007 & A1 2010 in now called out instead of IEC 61000-4-4:2004. The only change of note primarily affects the test lab as the verification of each CDN output is
mandatory, whereas in the previous version, such verification was only recommended.
Surge – IEC 61000-4-5:2005 with Cor. 2009 replaced IEC 61000-4-5:2001 and the reference standard. Phase positioning has been added along with output impedance tolerance of +/- 10%. Test equipment calibration is now required at 0.5, 1.0,
2.0 and 4.0 kV instead of verification only at 0.5 and 4.0 kV in the older version. CDN calibration now includes specific requirements for both L-L and L-G.
Power Frequency Magnetic Field – the reference standard has been updated to the IEC 61000-4-8:2010 from the 1993 version of the same standard. As in the 2006 version of EN61326-1, the magnetic immunity test is only required for the industrial
environment. A GRP is no longer required when testing table top devices. The test generator is prohibited from being near the test coil, and the It is important to note the companion standards to EN61326-1, EN61326-2-1, -2-2, -2-3, -2-4 and -2-5, have
also been updated. These standards call our particular requirements for product subsets in the scope of EN61326-1. For example, EN61326-2-2 provides particular requirements for portable test, measuring and monitoring equipment used in low voltage distribution
systems, which add to and potentially modify the requirements of EN61326-1
