Accredited radio testing of radio characteristics
One of the requirements for being able to append the CE marking to radio equipment is that the essential requirement of "effective use of spectrum" contained in the Radio Equipment Directive be met. One way of meeting this requirement is to test the equipment in accordance with harmonised standards. ETSI is the organisation responsible for developing these standards. If harmonised standards are not available, an EC-type examination certificate issued by a notified body is required. RISE (formerly SP) is a notified body for the Radio Equipment Directive.
RISE offers accredited radio testing according to the commonest European standards (ETSI) for both analogue and digital radio equipment from the low-frequency Hz range up to the microwave range (GHz).
The main purpose of testing radio equipment is to protect the radio spectrum from unnecessary interference. Most regions (including the EU, USA and Asia) have technical requirements that must be met before radio equipment can be sold or used.
Transmitter characteristics such as carrier wave frequency, power and signal purity, as well as certain aspects of receiver performance must be measured and must either be stated in the manufacturer's own declaration of conformity or be approved by an authority. Different countries and regions often have different technical requirements for radio transmitters.
RISE can also help with characterisation of antennas for radio equipment, and can provide services such as antenna diagram measurement, efficiency measurement and antenna gain measurement.
RISE is approved for testing for the North American market
All radio transmitters for use on the US market must be certified or type-approved by the US Federal Communications Commission (FCC).RISE is approved for FCC testing of the commonest types of radio equipment over the frequency range 9 kHz–100 GHz.
RISE is the only organisation in Sweden that has been appointed by the FCC as a Telecommunication Certification Body (TCB). This means that we can carry out the certification of radio transmitters that the FCC requires and therefore also issue approvals for the American market.
We can also perform corresponding tests for Canada (ISED) and help with certification/approval (FCB) for the Canadian market.
Under the terms of the Radio Equipment Directive, radio equipment in Europe must meet requirements in respect of EMC. One way of meeting this requirement is to test the Equipment in accordance with harmonised standards.
ETSI is the organisation responsible for developing these standards for EMC for radio equipment, and its ETSI EN 301 489 standard series prescribes the requirements for various types of radio equipment. Although the series covers most types of radio equipment, there are some exceptions. There may be separate product standards for such equipment.
Accredited EMC testing
EMC testing of radio transmitters consists of two parts: Emission requirements, which specify limits on the generation of undesired emissions via cables and power supplies; and immunity requirements, which specify the required immunity of the radio equipment to interference. Tests are performed for both radiated emissions and those conducted along external cabling.
RISE can offer accredited EMC testing in accordance with the commonest parts of the ETSI EN 301 489 standard series and other international EMC standards. We also have long experience of EMC testing in specific fields, such as military equipment and vehicles.
International EMC requirements outside Europe generally only specify requirements for emission measurements. Most regions and countries tend to use the CISPR standards for their EMC emission requirements. Immunity requirements are often not mandatory, but may be required in certain industries or activities, such as the telecommunications industry, hospitals and public administration.
For the North American market, EMC requirements consist only of emission measurement.
Electrical safety characteristics
The Radio Equipment Directive also includes requirements relating to the health and safety of the user. The Directive has requirements similar to those of the Low Voltage Directive. Under the Low Voltage Directive, certain kinds of equipment are exempt from the requirements if they operate at voltages below a certain level. However, the Radio Equipment Directive removes this exception, and this means that all radio equipment must be evaluated for electrical safety regardless of its voltage level.
The harmonised standards which apply for radio equipment are EN 60 950-1, EN 62368-1 and EN 60 215. RISE is accredited to all of these standards and can provide full electrical safety evaluation for radio equipment.
Electrical safety requirements for the US market
Electrical safety requirements for the US market are specified by the US Occupational Safety and Health Administration (OSHA), among other bodies. Equipment used in workplaces is required to be safe and certified by a body recognised by OSHA. Other bodies that specify safety requirements can include insurance companies and local authorities. There are no voltage limits similar to those specified in the EU's Low Voltage Directive.
We always recommend that our customers also carry out an electrical safety inspection for the US market. If this check is done in conjunction with an inspection for the EU market, the additional cost is minimal. Additional charges are made for certification and manufacturing inspection. The UL 60 950-1 telecommunications product standard is very similar to the EU's EN 60 950-1 standard. The new UL 62368-1 standard is also identical to IEC 62368-1.
