OUR SERVICES



Certification against North American and Canadian standards





The US and Canadian markets for electrical and electronic products are conditioned to accepting product approval marks and safety certification from a Nationally Recognised Testing Laboratory (NRTL). These labs are also recognised by the Occupational Safety & Health Administration (OSHA) to provide evaluation, testing and certification of products.


Cranage has many years of experience working with NRTL’s and our ILAC/UKAS accredited test reports can be accepted to show compliance against American (UL) and Canadian (CSA) standards. Our team of engineers can work with you to provide assistance and reduce the assessment time for gaining certification.


The key benefits Cranage can now offer:

• Test and evaluate products to North American standards either at Cranage, or on your premises

• Perform the mandatory factory inspections on certified products bearing the NRTL mark

• Evaluate “one-off’ products which are handled under ISO Type 1 certification and do not require factory surveillance or inspection

• Fast tracking service



Existing product approval arrangements can be easily transferred subject to passing a technical review. Products tested by Cranage and certified for use in North America include scientific instruments, professional audio equipment, vacuum cleaners, commercial laundry equipment, bottle labelling machines, electric hair straighteners and various types of medical equipment.




Pre-compliance testing for product development





We understand the time and cost involved with creating a product that is safe for its intended use and compliant with the necessary regulations. Cranage EMC and Safety offers pre-compliance testing to help identify any potential issues, helping you to save time and money.


The benefits of using our pre-compliance testing are:

• Test data can highlight areas of failure early on, allowing potential issues to be fixed

• Lowers long term testing and design costs

• Potentially reduce the time involved to get your product to the market

• We have a variety of EMC solutions available on site, to assist with problem solving

• Access to experienced and knowledgeable engineers

• Compliance standards, test facilities and equipment are still used throughout this process




On-site (in-situ) EMC Testing





If your equipment is large or in-situ we can offer testing at your premises.


In-situ EMC tests and measurements are usually undertaken in support of a Technical Construction File (TCF) for the equipment that is being tested.


Although it would not be feasible to perform tests in full accordance with the relevant technical standards, the testing methodology and procedures used by Cranage EMC have been assessed and approved for product certification. Testing will be performed to simulate actual operating conditions. It may be necessary to assess more than one mode of operation to maximise emissions or determine worst case susceptibility.


Cranage EMC can offer the following testing at your premises:


1) Conducted Emissions covering:

BS EN / IEC 61000-6-3: 2007 +A1: 2011

BS EN / IEC 61000-6-4: 2007 +A1: 2011

BS EN 55011: 2009 +A1: 2010

Frequency range: 9kHz to 30MHz


2) Radiated Electric Field Emissions covering:

BS EN / IEC 61000-6-3: 2007 +A1: 2011

BS EN / IEC 61000-6-4: 2007 +A1: 2011

BS EN 55011: 2009 +A1: 2010

Frequency range: 30MHz to 1000MHz


3) Conducted Susceptibility covering:

BS EN / IEC 61000-6-1: 2007

BS EN / IEC 61000-6-2: 2005

BS EN / IEC 61326-1: 2013

Frequency range: 150kHz to 400MHz

Test level: up to 10V rms (96dBµA)


4) Immunity to Electrical Fast Transient Bursts on Power Lines, Control, Signal and Earth Cables covering:

BS EN / IEC 61000-6-1: 2007

BS EN / IEC 61000-6-2: 2005

BS EN / IEC 61326-1: 2013

Test level: up to ± 4kV


5) Immunity to Electrostatic Discharge covering:

BS EN / IEC 61000-6-1: 2007

BS EN / IEC 61000-6-2: 2005

BS EN / IEC 61326-1: 2013

Test level: ± 15 air discharge on user accessible non-conductive areas ± 8 contact discharge on user accessible conductive areas


6) Radiated Electric Field Immunity covering:

BS EN / IEC 61000-6-1: 2007

BS EN / IEC 61000-6-2: 2005

BS EN / IEC 61326-1: 2013

Frequency range: spot frequencies are applied

Test level: up to 10V/m


We are also able to perform testing to the below standards:

BS EN / IEC 61000-3-2: 2014 Harmonic currents up to 16A per phase

BS EN / IEC 61000-3-12: 2011 Harmonic currents up to 75A per phase

BS EN / IEC 61000-3-3: 2013 Voltage fluctuations and flicker up to 16A per phase

BS EN / IEC 61000-3-11: 2000 Voltage fluctuations and flicker up to 75A per phase


Prior to testing, some thought should be given to creating a test plan, which should contain or reference the following:

-Electrical and mechanical details of the equipment under test (EUT)

-Specific EMC standards to be used or procedures to be followed

-List of tests, severities and durations which relate to the EUT taking into account response times or operating modes

-Performance evaluation specifications

-Special test equipment required to operate or simulate EUT performance, eg. load banks, power supplies, measuring or control equipment, telecommunication services, etc.

-Reporting requirements for assessing performance or acceptance tests

-Method of reporting errors, measurement deviations or performance failures during testing

-A test programme showing anticipated timescales

-Details of support, eg. site electrician/operative to maintain or restore functionality, spares in the event of damage, etc.

-Details of external cables, eg. shielded/unshielded, purpose, utilisation, achievable lengths, etc.
