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 TS 62966-3:2021 defines the requirements for operational and personal safety of aisle containments for IT cabinets.
The aim is to provide physical security for the IT equipment installed in the containment using the criteria “availability” and “safety”.
The requirements apply to all operational, working and maintenance procedures.
This document does not apply to ordinary persons, when using installations and equipment.
The requirements described herein are also intended to ensure that it is possible for authorized personnel to enter and remain in the containment (as accessible equipment) and to maintain or upgrade the systems installed in the containment without risk. It should also be possible to evacuate the containment quickly and safely at any time, especially in the event of a fire or any other hazardous situation, whilst reducing the health risk to personnel to a minimum.
Aspects relating to computing, data processing, data storage, building protection or the data centre itself do not fall within the scope of this document. Only those additional aspects arising from the integration of an aisle containment are considered.
The design and positioning of an aisle containment, which is integrated in the data centre, has influence on the following different aspects of operational safety:
a) escape and evacuation plans;
b) escape routes;
c) emergency exits;
d) functional aspects of escape doors;
e) lighting conditions
f) lighting and signposting of escape routes;
g) fire protection.
In this document, these operational safety requirements and recommendations are considered.
To achieve the highest effectiveness, all these requirements are considered as much as possible during the design of an aisle containment.
This document applies to normal operations, not to the initial installation of the containment.

IEC 61076-2-114:2020 describes circular connectors with M8 screw locking typically used for data and power transmissions in industrial applications. These connectors consist of fixed and free connectors that are either rewireable or non-rewireable. Data transmission performance is for Category 5 up to 100 MHz.
Two coded versions, identified as D-coded and P-coded, are provided that differ by their pin size and optionally by number of poles, hence by the function provided for field applications.
Male connectors have round contacts Ø 0,8 mm for D-coded, and Ø 1 mm for P-coded connectors.
The coding provided by this document prevents the mating of accordingly coded male or female connectors to any other similarly sized interfaces covered by other standards.

IEC 61076-2-012:2020 specifies circular connectors with an inner push‑pull locking mechanism of a size derived from and thus being compatible with M12 screw‑locking connectors and with mating interfaces according to IEC 61076‑2‑101, IEC 61076‑2‑109, IEC 61076‑2‑111 and IEC 61076‑2‑113.
A female fixed connector with inner push-pull locking according to this document is intermateable with a correspondingly coded male free connector with M12 screw-locking according to IEC 61076-2-101, IEC 61076-2-109, IEC 61076-2-111 or IEC 61076-2-113.
This document covers both:
a) power connectors with current ratings up to 16 A and voltage ratings up to 630 V, typically used for power supply of electrical equipment used in industrial premises, and
b) connectors for data and signal transmission with frequencies up to 500 MHz.
These connectors consist of both fixed and free connectors, either rewirable or non‑rewirable, with M12 inner push‑pull locking as explained above. Male connectors have round contacts from Ø0,6 mm up to Ø1,5 mm.
This document covers various types of connectors identified by their "codings" with different contact arrangement, not mutually interchangeable.
The design of the inner push‑pull mechanism prevents the unintended mating of the male inner push‑pull free connector with the female connector with M12 screw‑locking even for identical coding.
Some styles of free connectors with female contacts covered in this document are equipped with both inner and outer push-pull locking for intermateability also with correspondingly coded male fixed or free connectors according to IEC 61076-2-010.

IEC 60352-5:2020 s’applique aux connexions press-in sans soudure pour utilisation dans les équipements et composants électriques et électroniques.
