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 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 61000-3-11: 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.
