This part of IEC 62037 defines a radiated passive intermodulation (PIM) test to determine PIM levels generated by a device or object when it is exposed to RF radiation.  This test can be conducted on any material or object and is not limited to devices designed to propagate RF signals.  This test can be conducted as either a near field or far field test as defined by the test specification.

This document specifies the standard measurement conditions and measuring methods for determining optical properties of the virtual image created by 3D display devices such as head-up displays. The virtual image refers to an image in which the 3D visual information is superimposed with the outside world. Eye-wear type displays are however beyond the scope of this standard.

This part of the IEC 61300 series is concerned with the observation and classification of debris (removeable particles on the surface of a fibre/ferrule), scratches and defects (non-removeable features on the surface of a fibre/ferrule). The inspection requirements are based on IEC TR 62627-05. Advice for cleaning of contamination from fibres/ferrule is found in IEC TR 62627-01 and a recommendation is given in Annex E. Visual inspection is in addition to, and does not replace measurement of performance parameters such as attenuation and return loss, or end face parameters. The dimensions specified are chosen such that they can be easily estimated. Not only the zones A and B on the fibre are to be inspected for defects and scratches but the whole contact area (where the two fibres/ ferrules meet when mated) needs to be inspected for contamination (This is up to 250 µm diameter for cylindrical ferrules and the whole ferrule surface for rectangular ferrules).

The objectives of this standard are to:

specify the minimum criteria a microscope is to meet to be compliant to this standard;

specify the procedure and criteria for inspecting fibre-optic end faces for cleanliness to determine if the end faces are fit for use. All connector optical interfaces (IEC 61755 series and IEC 63267 series) are based on physical contact between fibre cores;

provide quantitative criteria for the analysis of end face images.

This International Standard applies to the basic safety and essential performance of me equipment and me systems intended to be used for projection radiography and indirect radioscopy. IEC 60601-2-43 applies to me equipment and me systems intended to be used for interventional applications and refers to applicable requirements in this particular standard.

me equipment and me systems intended to be used for bone or tissue absorption densitometry, computed tomography, mammography or dental or radiotherapy applications are excluded from the scope of this International Standard. The scope of this International Standard also excludes radiotherapy simulators.

If a clause or subclause is specifically intended to be applicable to me equipment only, or to me systems only, the title and content of that clause or subclause will say so. If that is not the case, the clause or subclause applies both to me equipment and to me systems, as relevant.

This part of IEC 63171 covers shielded and unshielded free and fixed multimedia connectors (MMC in the following, see 3.1) for data transmission with frequencies up to and above 3 000 MHz for shielded and up to 600 MHz for unshielded connectors, both with current-carrying capacity with up to 8 ways. It specifies the common dimensions, mechanical, electrical and transmission characteristics and environmental requirements as well as test specifications, respectively.

The form factor of these MMC 1-pair connectors is smaller than a quarter of a connector of the
IEC 60603-7 series (RJ45) or similar connectors and allows to use them for cable sharing with already installed structured cabling. Such a connector, the MMC 4-pair is also described herein.

NOTE – The overall performance of the transmission channel in such case must be evaluated.

For industrial applications, the connector might be used in circular connectors like M12 screw locking as described in IEC 61076-2-101 or other preferred locking.

This part of IEC 63171 covers type 4 connectors. Each part of this series has the associated type of number equal to the number of the part in the series. All connectors in the IEC 63171 series are deemed to provide the same functions as defined in IEC 63171, using different mechanical interfaces.

The shielded and unshielded connectors are interoperable for their internal transmission performance and can be exchanged. The shielded version has improved EMC and coupling properties.

The connectors are intended to be used for Single Pair Ethernet (SPE) according but not restricted to the following IEEE standards: 10Base-T1 (IEEE 802.3cg), 100Base-T1 (IEEE 802.3bw), 1000Base-T1 (IEEE 802.3bp), Multi-Gig Base-T1 (IEEE 802.3ch) and optionally with Power over Data line (PoDL) power supply according to IEEE 802.3bu.
