This part of IEC 60974 specifies safety and performance requirements for gas consoles intended to be used with combustible gases or oxygen. These gas consoles are designed to supply gases for use in arc welding, plasma cutting, gouging and allied processes in non-explosive atmospheres.

The gas console can be external or internal to the power source enclosure. In the latter case, this standard also applies to the power source.

NOTE See Annex A for mechanised plasma system diagram.

This document gives guidance on specifying required dependability requirements and collating these requirements in a specification, together with the means of assuring the achievement of those requirements.

The guidance provided includes:

specifying quantitative and qualitative reliability, maintainability, supportability and availability requirements;

advising purchasers on how to ensure that the requirements will be fulfilled by suppliers;

advising suppliers to help them meet the purchaser’s requirements.

Other obligations, such as legislation and governmental regulation may also place requirements on items and these should be applied in addition to any requirements derived in accordance with this standard.

Whilst mainly addressing system and equipment level dependability, many of the techniques described in the different parts of IEC 60300 can also be applied to products or at the component level. The term item is used throughout this standard.

NOTE 1 This guide does not directly consider safety and environment specifications although much of the guidance in this standard could also be applied to them.

NOTE 2 This guide does not consider the specification of the dependability of a service, including those provided through Public-Private Partnership procurements.

NOTE 3 The guidance in this document may be applied to some aspects of the specification of requirements relating to software but specific guidance may be found in IEC 62628 and the different parts of IEC 61508.

Part 3-3 of IEC 62321 specifies the screening and semi-quantitative analysis of polybrominated biphenyls (PBBs), polybrominated diphenyl ethers (PBDEs), di-isobutyl phthalate (DIBP), di-n-butyl phthalate (DBP), benzylbutyl phthalate (BBP), di-(2-ethylhexyl) phthalate (DEHP), di-n-octyl phthalate (DNOP), di-isononyl phthalate (DINP), and di-isodecyl phthalate (DIDP)  in polymers of electrotechnical products using the analytical technique of gas chromatography-mass spectrometry using a pyrolyzer/thermal desorption accessory. (Py/TD-GC-MS).

This test method has been evaluated by the test of PP (polypropylene), PS (polystyrene), and PVC (polyvinyl chloride) materials containing the analyte in the range of 100 mg/kg to 1 000 mg/kg. Use of the methods described in this document for other polymer types, PBBs (mono-deca), PBDEs (mono-deca) and the phthalates or concentration ranges other than those specified above has not been specifically evaluated.

This International Standard contains limits and procedures for the measurement of radio disturbances in the frequency range of 150 kHz to 5 925 MHz. This standard applies to vehicles, boats, internal combustion engines, trailers, devices and any electronic/electrical component intended for use in vehicles, boats, trailers and devices. Refer to International Telecommunications Union (ITU) publications for details of frequency allocations. The limits are intended to provide protection for on-board receivers installed (per the manufacturer’s guidelines) in a vehicle from disturbances produced by components/modules in the same vehicle.

The receiver types to be protected are, for example, broadcast receivers (sound and television), land mobile radio, radio telephone, amateur, citizens' radio, Satellite Navigation (GPS etc.), Wi-Fi, C2X, and Bluetooth.

This International Standard does not include protection of electronic control systems from radio frequency (RF) emissions or from transient or pulse-type voltage fluctuations. These subjects are included in ISO publications.

The limits in this standard are recommended and subject to modification as agreed between the vehicle manufacturer and the component supplier. This standard is also intended to be applied by manufacturers and suppliers of components and equipment which are to be added and connected to the vehicle harness or to an on-board power connector after delivery of the vehicle.

This standard defines test methods for use by Vehicle Manufacturers and Suppliers, to assist in the design of vehicles and components and ensure controlled levels of on-board radio frequency emissions.
