This document  applies primarily to electro-technical equipments but its application can be extended to other equipments and to components.

Also if some sort of analysis is always performed when making a seismic qualification, e.g. for the choice of the representative sample to be tested or for the extension of the seismic qualification from the tested specimen to similar specimens, the verification of the performance of an equipment by analysis or by a combination of testing and analysis may be acceptable but is outside the scope of this guide, which is restricted to verification based entirely upon data from dynamic testing.

This guide deals solely with the seismic testing of a full-size equipment which can be tested on a vibration table. The seismic testing of an equipment is intended to demonstrate its ability to perform its required function during and/or after the time it is subjected to the stresses and displacements resulting from an earthquake.

The object of this guide is to present a range of methods of testing which, when prescribed by the relevant specification, can be applied to demonstrate the performance of equipments for which seismic testing is required with the main aim of achieving qualification.

NOTE Qualification by so-called “fragility-testing” is not considered to be within the scope of this guide which has been prepared to give generally applicable guidance on seismic testing and specifically on the use of IEC 60068-2 test methods.

The choice of the method of testing can be made according to the criteria described in this guide. The methods themselves are closely based on published IEC test methods.

This guide is intended for use by manufacturers to substantiate, or by users to evaluate and verify, the performance of an equipment.

Class A:       thin wall         shrink ratio 2:1      internal diameter up to 102,0 mm

Class B:       medium wall    shrink ratio 2:1      internal diameter up to 60,0 mm

Class C:       thick wall        shrink ratio 2:1      internal diameter up to 51,0 mm

Class D:       medium wall    shrink ratio 3:1      internal diameter up to 40,0 mm

These sleevings are normally supplied in the following colours: black, red, green, blue, white, yellow and green/yellow.

Sizes or colours other than those listed in this standard may be available as custom items. These items shall be considered to comply with this standard if they comply with the property requirements listed in tables 5, 6, 7 and 8, excluding dimensions and mass.

Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone.

This part of IEC 60050 gives the general terminology used in lighting, as well as general terms pertaining to specific applications and associated technologies. This second edition reviews and complements the previous one. It has the status of a horizontal standard in accordance with IEC Guide 108, Guidelines for ensuring the coherency of IEC publications – Application of horizontal standards.

This terminology is consistent with the terminology developed in the other specialized parts of the IEV.

This horizontal standard is primarily intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 108.

One of the responsibilities of a technical committee is, wherever applicable, to make use of horizontal standards in the preparation of its publications.

This International Standard specifies protocols and test procedures for the reproducible and conservative measurement of the peak spatial average SAR (psSAR) induced inside a simplified model of the head or the body by radio-frequency (RF) transmitting devices, with a defined measurement uncertainty. The protocols and procedures apply to a significant majority of the population including children during the use of hand-held and body-worn wireless communication devices. These devices may include single or multiple transmitters or antennas, and may be operated with their radiating structure(s) at distances up to 200 mm from a human head or body. This standard can be employed to evaluate SAR compliance of different types of wireless communication devices used next to the ear, in front of the face, mounted on the body, operating in conjunction with other RF-transmitting, non-transmitting devices or accessories (e.g. belt-clip), or embedded in garments. The applicable frequency range is from 4 MHz to 10 GHz. Devices operating in the applicable frequency range can be tested using the phantoms and other requirements defined in this standard.

The device categories covered include but are not limited to mobile telephones, cordless microphones, and radio transmitters in personal, desktop and laptop computers for  multi-band operations using single or multiple antenna, including push-to-talk devices. Wireless power transfer devices operating above 4 MHz may also apply this International Standard.

This standard is not intended to apply to implanted medical devices.

This part of IEC 60684 gives the requirements for two types of heat-shrinkable, polyolefin sleeving for bus-bar insulation, with a nominal shrink ratio of 2,5:1.

This sleeving has been found suitable up to temperatures of 100 °C.

< >< >

These sleevings are normally supplied in colour, red or brown.

Since these types of sleevings cover a significantly large range of sizes and wall thicknesses, Tables A.1 and A.2 provide guidance to the range of sizes available. The actual size and wall thickness shall be agreed between the user and supplier depending on the electric strength of the installed tubing offered and the requirements of the user.

Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone.
