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.

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.

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.

IEC 60352-9:2024 provides guidelines for welding and testing of ultrasonically welded connections and includes requirements, tests and practical guidance information. Ultrasonic welding is a form of cold friction welding that is becoming increasingly popular in many industries. This type of welding uses ultrasonic vibration to join materials together, creating a bond that is both strong and reliable. Ultrasonic welding has been identified as a process in ISO 4063-41 by the International Organization for Standardization (ISO). The process of ultrasonic welding relies on high frequency ultrasound waves being used to create frictional heat at the connection point. High temperature is not required for this special method of welding, making it one of the most cost-effective ways to join two materials together. It also requires fewer steps than traditional methods, meaning it can be completed quickly and with minimal resources. Ultrasonic welding has been around for decades but only recently has become more widely utilized due to advances in technology and its availability at lower cost. It can be used on many different materials including plastics, rubbers, metals, textiles, and composites. Due to its precision and strong bonds it creates, it has become extremely popular in manufacturing processes such as automotive industry, electronics industry, furniture production and even medical device production. This document covers ultrasonically welded connections made with stranded or flexible wires (class 2, 5 or 6 per IEC 60228) of copper or copper alloy, as well as of aluminium or aluminium alloy. These welded metal-to-metal connections shall employ wires with cross-sectional area of 0,08 mm2 to 160 mm2 and shall not exceed a total cross-sectional area, in case of wire bundle, of 200 mm2. For aluminium or aluminium alloy wires, the minimum required cross-sectional area is 2,5 mm2. Additionally, information on materials, data from industrial experience and test procedures are included to ensure electrically stable connections under prescribed environmental conditions. Lastly, this document aims to achieve comparable results when using ultrasonic welding equipment with similar performance and specifications as specified by the termination manufacturer.
