This document is applicable to multifactor evaluation of an EIS for applications where the stresses of the application are a combination of the factors identified in IEC 60505. The severe operating conditions are expected to occur during operation at elevated temperatures.

This document establishes the procedure to evaluate the influence of stresses on the performance established following the thermal classification of the EIS. The thermal classification is established in Step 1 where the only ageing factor is thermal. The candidate EIS is first evaluated based on thermal stress only. This evaluation is defined as the baseline of the candidate EIS. In Step 2, the evaluation of the additional factors applied at elevated temperatures provides the measurement needed to establish the influence of the additional factors on the performance of the baseline EIS.

This document is about thermal endurance testing with one or more stress factors added during the thermal ageing process. It provides guidance regarding interpretation of the test results.

The performance of any product designed and constructed using the EIS established in accordance with this document shall be evaluated in accordance with the application requirements set by the appropriate IEC Technical Committee.

This part of IEC 62488 applies to power line carrier terminals and networks used to transmit information over power networks including extra high, high and medium voltage (EHV/HV/MV) power lines using both digital and optionally analogue modulation systems in a frequency range between 16 kHz and 1MHz (see also IEC 62488-1).

 

In many countries, power line carrier (PLC) channels represent a significant part of the utility-owned telecommunication system. A circuit normally routed via a PLC channel can also be routed via a channel using a different transmission medium such as point to point radio, optical fibre or open wire circuit.

 

It is therefore important that the input and output interfaces that are used between terminals in the communication system are standardised.

 

The issues requiring consideration of DPLC and/or APLC devices as parts of a telecommunication network can be found in IEC 62488-1.

Figure 1 shows the correspondence between the elements needed to implement PLC systems and the related International Standards.

This International Standard defines the measurement method for the determination of the durability of radio frequency (RF) surface acoustic wave (SAW) and bulk acoustic wave (BAW) devices, such as filters and duplexers, with respect to high power RF signals, which are used in telecommunications, measuring equipment, radar systems and consumer products.

The IEC 63155 includes basic properties of failure of RF SAW/BAW devices, and guidelines to setup the measurement system and to establish the procedure to estimate their time to failure (TF) of RF SAW/BAW devices. Since TF is mainly governed by the applied RF power in the devices, discussions are focused on the power durability.

It is not the aim of this standard to explain theory, nor to attempt to cover all the eventualities which may arise in practical circumstances. This standard draws attention to some of the more fundamental questions, which shall be considered by the user before he/she places an order for an RF SAW/BAW device for a new application. Such a procedure will be the user's insurance against unsatisfactory performance related to premature device failure resulting from high-power exposure of RF SAW/BAW devices.

This part of IEC 60749 describes a test used to determine whether encapsulated solid state devices used for through-hole mounting can withstand the effects of the temperature to which they are subjected during soldering of their leads by using wave soldering.

In order to establish a standard test procedure for the most reproducible methods, the solder dip method is used because of its more controllable conditions. This procedure determines whether devices are capable of withstanding the soldering temperature encountered in printed wiring board assembly operations, without degrading their electrical characteristics or internal connections.

This test is destructive and may be used for qualification, lot acceptance and as a product monitor.

The heat is conducted through the leads into the device package from solder heat at the reverse side of the board. This procedure does not simulate wave soldering or reflow heat exposure on the same side of the board as the package body.

This International Standard describes methods for establishing seismic qualification procedures that will yield quantitative data to demonstrate that the equipment can meet its performance requirements. This standard is applicable to electrical, mechanical, instrumentation and control equipment/components that are used in nuclear facilities. This standard provides methods and documentation requirements for seismic qualification of equipment to verify the equipment’s ability to perform its specified performance requirements during and/or after specified seismic demands. This standard does not specify seismic demand or performance requirements. Other aspects, relating to quality assurance, selection of equipment, and design and modification of systems, are not part of this standard. As seismic qualification is only a part of equipment qualification, this standard shall be used in conjunction with IEC/IEEE 60780-323.

The seismic qualification shall demonstrate equipment’s ability to perform its safety function(s) during and/or after the time it is subjected to the forces resulting from at least one safe shutdown earthquake (SSE/S2). This ability shall be demonstrated by taking into account, prior to the SSE/S2, the ageing of equipment and the postulated occurrences of a given number of earthquakes of lower intensity operating basis earthquake (OBE/S1). Ageing phenomena to be considered, if specified in the design specification, are those which could increase the vulnerability of equipment to vibrations caused by an SSE/S2.

This International Standard applies to the classification of degrees of protection provided by enclosures for rotating electrical machines. It defines the requirements for protective enclosures that are in all other respects suitable for their intended use and which, from the point of view of materials and workmanship, ensure that the properties dealt with in this standard are maintained under normal conditions of use.

This document does not specify degrees of protection against mechanical damage of the machine, or conditions such as moisture (produced for example by condensation), corrosive dust and vapour, fungus or vermin.

This document is also applicable to explosion proof machines, but it does not specifiy the types of protection for use in a potentially explosive (dust, gas) environment. Those are defined in the IEC 60079 series of standards.

In certain applications (such as agricultural or domestic appliances), more extensive precautions against accidental or deliberate contact may be specified.

This standard gives definitions for standard degrees of protection provided by enclosures applicable to rotating electrical machines as regards the:

a)  protection of persons against contacts with or approach to live parts and against contact with moving parts (other than smooth rotating shafts and the like) inside the enclosure and protection of the machine against ingress of solid foreign objects;

b)  protection of machines against the harmful effects due to ingress of water;

c)  protection of machines against the harmful effects due to ingress of dust.

It gives designations for these protective degrees and tests to be performed to check that the machines meet the requirements of this standard.
