CISPR 16-1-5:2014/AMD1:2016:

167880_188449177838127_100000191372113_773449_1804246_nThe International Electrotechnical Commission (IEC) has released CISPR 16-1-5:2014/AMD1:2016 . This standard includes Amendment 1 – Specification for radio disturbance and immunity measuring apparatus and methods – Part 1-5: Radio disturbance and immunity measuring apparatus – Antenna calibration sites and reference test sites for 5 MHz to 18 GHz and is now available on the IEC webstore.

Description: “CISPR 16-1-5:2014+A1:2016 specifies the requirements for calibration sites in the frequency range 5 MHz to 18 GHz used to perform antenna calibrations according to CISPR 16-1-6. It also specifies the requirements for reference test sites that are used for the validation of compliance test sites in the frequency range 30 MHz to 1 000 MHz according to CISPR 16-1-4. It has the status of a basic EMC standard in accordance with IEC Guide 107. Measurement instrumentation specifications are given in CISPR 16-1-1 and CISPR 16-1-4. Further information and background on uncertainties in general is given in CISPR 16-4, which can also be helpful in establishing uncertainty estimates for the calibration processes of antennas and site validation measurements. This second edition cancels and replaces the first edition published in 2003, and its Amendment 1 (2012). It constitutes a technical revision which includes the following significant technical changes with respect to the previous edition:

– site validation methods for other sites covered in CISPR 16-1-6 are added;
– smaller step sizes are specified for swept frequency measurements;
– the minimum ground plane size is increased;
– and other miscellaneous technical and editorial refinements are included

VSWR and its Effects on Power Amplifiers

Voltage Standing Wave Ratio results from an impedance mismatch between a source (an amplifier) and a load (test application). This mismatch can influence the performance of the source.

UL has released UL 2272 Ed. 1, the first edition of the standard for Electrical Systems for Personal E-Mobility Devices, UL 2272, has been issued and can now be purchased on the UL website

- From Our Sponsors -

Description: “These requirements cover the electrical drive train system including the battery system, other circuitry and electrical components for electric powered scooters and other devices to be referred to as personal e-mobility devices as defined in this standard.

1.2 This standard is intended for evaluation of the safety of the electrical drive train system and battery and charger combination for energy and electrical shock hazards and does not evaluate the performance or reliability of these devices. In addition, it does not evaluate the physical hazards that may be associated with the use of personal e-mobility devices.”

UL Standard 60730-2-6, Edition 3:

img_35244UL has released UL 60730-2-6, Edition 3, Standard for Automatic Electrical Controls – Part 2-6: Particular Requirements for Automatic Electrical Pressure Sensing Controls Including Mechanical Requirements and can now be purchased on the UL website

Description: “This part of IEC 60730 applies to automatic electrical pressure Sensing Controls with a minimum gauge pressure rating of – 60 kPa and a maximum gauge pressure rating of 4,2 MPa, for use in, on or in association with, equipment. The equipment may use electricity, gas, oil, solid fuel, solar thermal energy, etc. or a combination thereof.

This standard is also applicable to individual pressure Sensing Controls utilized as part of a Control System or pressure Sensing Controls which are mechanically integral with multifunctional controls having non-electrical outputs.

Automatic electrical pressure Sensing Controls for equipment used by the public, such as equipment intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard.”
