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 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.

IEC 62443-2:2023 specifies a comprehensive set of requirements for security-related processes that IACS service providers can offer to the asset owner during integration and maintenance activities of an Automation Solution. Because not all requirements apply to all industry groups and organizations, Subclause 4.1.4 provides for the development of "profiles" that allow for the subsetting of these requirements. Profiles are used to adapt this document to specific environments, including environments not based on an IACS. NOTE 1 The term "Automation Solution" is used as a proper noun (and therefore capitalized) in this document to prevent confusion with other uses of this term. Collectively, the security processes offered by an IACS service provider are referred to as its Security Program (SP) for IACS asset owners. In a related specification, IEC 62443-2-1 describes requirements for the Security Management System of the asset owner. NOTE 2 In general, these security capabilities are policy, procedure, practice and personnel related. Figure 1 illustrates the integration and maintenance security processes of the asset owner, service provider(s), and product supplier(s) of an IACS and their relationships to each other and to the Automation Solution. Some of the requirements of this document relating to the safety program are associated with security requirements described in IEC 62443-3-3 and IEC 62443-4-2. NOTE 3 The IACS is a combination of the Automation Solution and the organizational measures necessary for its design, deployment, operation, and maintenance. NOTE 4 Maintenance of legacy system with insufficient security technical capabilities, implementation of policies, processes and procedures can be addressed through risk mitigation.
