Guidelines to standardisers of Collective Transport Systems - Needs of older people and persons with disabilities - Part 1: Basic Guidelines
SIST EN 60728-1-1:2014

IEC 60728-1-1:2014 is applicable to RF cabling for two-way home networks with wired cords or wireless links inside a room and primarily intended for television and sound signals operating between about 5 MHz and 3 000 MHz. The frequency range is extended to 6 000 MHz for distribution techniques that replace wired cords with a wireless two-way communication. This second edition cancels and replaces the first edition published in 2010, and constitutes a technical revision. It includes the following changes: update of performance requirements in Clause 5 to include those for DVB-T2 signals.

Measurement of internal electric field in insulating materials - Pressure wave propagation method
SIST EN IEC 62836:2024

IEC 62836:2024 provides an efficient and reliable procedure to test the internal electric field in the insulating materials used for high-voltage applications, by using the pressure wave propagation (PWP) method. It is suitable for a planar and coaxial geometry sample with homogeneous insulating materials of thickness larger or equal to 0,5 mm and an electric field higher than 1 kV/mm, but it is also dependent on the thickness of the sample and the pressure wave generator. This first edition cancels and replaces IEC TS 62836 published in 2020. This edition includes the following significant technical changes with respect to IEC TS 62836: a) addition of Clause 12 for the measurement of space charge distribution in a planar sample; b) addition of Clause 13 for coaxial geometry samples; c) addition of Annex D with measurement examples for coaxial geometry samples; d) addition of a Bibliography; e) measurement examples for a planar sample have been moved from Clause 12 in IEC TS 62836 to Annex C.

Underwater acoustics - Calibration of acoustic wave vector receivers in the frequency range 5 Hz to 10 kHz
SIST EN IEC 63305:2024

IEC 63305:2024 specifies methods and procedures for calibration of vector receivers in the frequency range 5 Hz to 10 kHz, which are applicable to vector receivers based on the two different principles. In addition, it describes an absolute method of inertial vector receiver calibration in air using optical interferometry. Usually, acoustic wave vector receivers are designed and constructed based on one of two principles. One is the sound pressure difference (gradient) principle. When measuring with this sensor, the vector receiver is rigidly fixed on a mount and supported in water. The other is the co-vibrating (inertial) principle. When measuring with this sensor, the vector receiver is suspended on a mount and supported in water in a non-rigid manner, which allows the vector receiver co-vibrate in the same direction as the sound particle in the sound wave field. Many methods have been used to calibrate vector receivers, such as free-field calibration, calibration in standing wave tube and calibration in a travelling wave tube.

SIST EN IEC 61169-70:2024

IEC 61169-70:2024, which is a sectional specification (SS), provides information and rules for the preparation of detail specifications (DS) of HD-BNC series RF coaxial connectors together with the pro forma blank detail specification. HD-BNC series connectors with characteristic impedance of 75 Ω are used with RF cables or micro-strips in microwave, telecommunication, wireless and other fields. The operating frequency limit is up to 18 GHz. It also prescribes mating face dimensions for general purpose connectors, gauging information and tests selected from IEC 61169-1, applicable to all detail specifications relating to series HD-BNC RF connectors. This specification indicates the recommended performance characteristics to be considered when writing a detail specification and it covers test schedules and inspection requirements for assessment levels M and H.

Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 2-44: Tests - Flexing of the strain relief of fibre optic devices and components
SIST EN IEC 61300-2-44:2024

IEC 61300-2-44:2024 specifies a test to determine the influence of flexing under tensile load of the strain relief of fibre optic interconnecting devices or components. The intention is to simulate the number of flexing cycles which would typically be experienced during service life. This test is applied to both single fibre cable and multiple fibre cable. This fourth edition cancels and replaces the third edition published in 2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) replaced active monitoring with transient loss for measurements during test; b) harmonized recommended severities according to IEC 61753-1.
