IVAV - Safety of avdio, video and similar electronic equipment

This International Standard defines measurement methods for
– d.c. or a.c. current of sinusoidal or non-sinusoidal waveform, which could flow through the
human body, and
– current flowing through a protective conductor.
The measuring methods recommended for TOUCH CURRENT are based upon the possible
effects of current flowing through a human body. In this standard, measurements of current
through networks representing the impedance of the human body are referred to as
measurements of TOUCH CURRENT. These networks are not necessarily valid for the bodies of
animals.
The specification or implication of specific limit values is not within the scope of this standard.
IEC TS 60479 series provides information regarding the effects of current passing through
the human body from which limit values may be derived.
This standard is applicable to all classes of EQUIPMENT, according to IEC 61140.
The methods of measurement in this standard are not intended to be used for
– TOUCH CURRENTS having less than 1 s duration,
– patient currents as defined in IEC 60601-1,
– a.c. at frequencies below 15 Hz, and
– currents above those chosen for ELECTRIC BURN limits.
This basic safety publication is primarily intended for use by technical committees in the
preparation of standards in accordance with the principles laid down in IEC Guide 104 and
ISO/IEC Guide 51. It is not intended for use by manufacturers or certification bodies
independent of product standards.
One of the responsibilities of a technical committee is, wherever applicable, to make use of
basic safety publications in the preparation of its publications. The requirements, test
methods or test conditions of this basic safety publication only apply when specifically
referred to or included in the relevant publications.

This International Standard defines routine electrical safety test procedures for use during
or after manufacturing of complete equipment, sub-assemblies or components, complying with
IEC 60065, IEC 60950-1 or IEC 62368-1 and powered by an a.c. mains supply or d.c. mains
supply, to detect manufacturing failures and unacceptable tolerances in manufacturing and
materials.
NOTE All the tests defined in this standard do not necessarily have to be performed at the end product
manufacturing location. The optimal location for the routine electrical safety tests can be defined by the
equipment manufacturer and reviewed under the conformity assessment scheme.

EN 50514 defines routine test procedures for use during or after manufacturing of complete equipment, sub-assemblies or components, certified or declared as complying with EN 60065 or EN 60950-1 and powered by an a.c. or d.c. mains supply. It defines the ROUTINE ELECTRICAL SAFETY TEST and their procedures to be applied during or at the end of the manufacturing process of apparatus certified or declared as complying with EN 60065 or EN 60950-1. The application of the tests detailed in this European Standard is design dependent and needs to be defined by the manufacturer.

The scope of this European Standard is to set up a suitable measuring methodology allowing accurate measurement of the maximum sound pressure level produced by consumer's headphones and earphones when associated with personal music players. Requested features: - The method should be reproducible and easily applicable to every type and shape of headphone or earphone available on the market (good mechanical adaptability). - As safety and health are addressed, the method should faithfully reflect the pressure level effective at the user's ear (good correlation with subjective tests) to support protection against excessive sound pressure from personal music players (the limits themselves are found in EN 60950-1:2006/A12:2011 and EN 60065:2002/A12:2011 respectively). - And finally, it is desirable to establish a global measuring procedure, including each component in the chain: Portable set + specific test signal + associated headphone or earphone. The standard is split into two parts: - Part 1 deals with sets provided as a package equipment by the manufacturer. In this case, "Personal music players" means the association of one set (compact cassette player, FM radio receiver, digital media player, streaming audio player…) with supplied headphones or earphones. - Part 2 gives guidelines to associate portable audio sets (FM radio receiver, digital media player, streaming audio player…) with headphones or earphones provided separately by any source. And the package sets with standardised connectors or interfaces between the two allowing to combine components of different manufacturers or different design.

This Part 2 of EN 50332 specifies methods of measuring the matching values for the use of personal music players and headphones/earphones defined for the use with those and with standardised connectors or interfaces allowing to combine components of different manufacturers or different design sold separately in order to avoid possible hearing impairment by excessive sound pressure resulting from them. Compared with “one-package sets“ the sound pressure level at the ear cannot be fixed by only one condition but needs at least two characteristics, one each for player and the headphones/earphones, defined by the matching values for their connection. Requirements for protection against excessive sound pressure from personal music players are given in EN 60950-1:2006/A12:2011 and EN 60065:2002/A12:2011.

This standard is applicable to mains-powered or battery-powered information technology equipment, including electrical business equipment and associated equipment, with a RATED VOLTAGE not exceeding 600 V. This standard is also applicable to such information technology equipment: - designed for use as telecommunication terminal equipment and TELECOMMUNICATION NETWORK infrastructure equipment, regardless of the source of power; - designed and intended to be connected directly to, or used as infrastructure equipment in, a CABLE DISTRIBUTION SYSTEM, regardless of the source of power; - designed to use the AC MAINS SUPPLY as a communication transmission medium (see Clause 6, Note 4 and 7.1, Note 4). This standard is also applicable to components and subassemblies intended for incorporation in information technology equipment. It is not expected that such components and subassemblies comply with every aspect of the standard, provided that the complete information technology equipment, incorporating such components and subassemblies, does comply.

Concepts, safety requirements and tests as  references to EN 60950 are given for equipment to be  connected to telecommunication networks in order to  reconcile the relevant equipment safety standards with  the considerable safety requirements of  telecommunication network operators for the operation  of their networks.

This International Standard applies to all audio/video, information and communication technology equipment marketed as final products, hereafter referred to as products. Although this standard does not explicitly apply to individual components and subassemblies to be incorporated into final products, component manufacturers also need to consider this standard, to enable manufacturers using such components to meet the requirements herein. Only the intended use of products as defined by the manufacturer is within the scope of this standard. This standard specifies requirements and recommendations for the design of environmentally sound products regarding life cycle thinking aspects, material efficiency, energy efficiency, consumables and batteries, chemical and noise emissions, extension of product lifetime, end of life, hazardous substances/preparations, and product packaging. This standard covers only criteria directly related to the environmental performance of the product. Criteria such as safety, ergonomics and electromagnetic compatibility (EMC) are outside the scope of this standard and covered by other standards.
