Environmental testing - Part 2-55: Tests - Test Ee and guidance - Loose cargo testing including bounce

IEC 60068-2-55:2013 provides a standard procedure for determining the ability of a specimen to withstand specified severities of bounce, e. g. when transported as loose cargo on wheeled vehicles. This second edition cancels and replaces the first edition, published in 1987, and constitutes a technical revision. The main changes with respect to the previous edition are listed below: This new edition allows for loose cargo testing in a more general sense. The test is no longer aligned with a special testing machine but allows for use of any suitable equipment such as electrodynamic or servo-hydraulic shaker tables. Moreover, sinusoidal and random vibration can be used. The previous rotation table motions are included in Annex A as historical methods.
This publication is to be read in conjunction with IEC 60068-1:1988.

IEC 60068-2-78:2012 is available as IEC Standards+ 60068-2-78:2012 which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 60068-2-78:2012 establishes a test method for determining the ability of components or equipment to withstand transportation, storage and use under conditions of high humidity. The object of this standard is to investigate the effect of high humidity at constant temperature without condensation on a specimen over a prescribed period. It is applicable to small equipment or components as well as large equipment, and can be applied to both heat-dissipating and non-heat-dissipating specimens. This second edition cancels and replaced the first edition, published in 2001 and constitutes a technical revision. This edition includes editorial and format changes with respect to the previous edition:
- The test chamber from IEC 60068-3-6 has been introduced.

IEC 60068-2-80:2005(Main)
Environmental testing - Part 2-80: Tests - Test Fi: Vibration - Mixed mode

IEC 60068-2-80:2005 Intended for general application for testing specimens when simulation is required of vibration excitation of a complex and mixed nature. The purpose of the test is to demonstrate the adequacy of the specimen to resist the specified mixed mode excitation without unacceptable degradation of its functional and/or structural performance. It is particularly useful for tailoring mixed mode environments where measured data are available for the real life environment. The test also helps reveal the accumulated effects of stress induced by random vibration, mixed with sine and/or random, and the resulting mechanical weakness and degradation in specified performances, and to use this information, in conjunction with the relevant specification, to assess the acceptability of specimens. In some cases, this standard may also be used to demonstrate the mechanical robustness of specimens. This standard is applicable to specimens which may be subjected to vibration of a random and/or a combination of random and deterministic nature resulting from transportation or real life environments, for example in aircraft, space vehicles and for items in their transportation container when the latter may be considered as part of the specimen itself. Although primarily intended for electrotechnical specimens, this standard is not restricted to such specimens and may be used in other fields where desired.

Environmental testing - Part 3-8: Supporting documentation and guidance - Selecting amongst vibration tests

Provides guidance for selecting amongst the IEC 60068-2 stationary vibration test methods Fc sinusoidal, Fh random and F(x) Mixed mode vibration. The different steady-state test methods and their aims are briefly described in Clause 4. Transient test methods are not included. For vibration testing, the environmental conditions, especially the dynamic conditions for the specimen, should be known. This standard helps to collect information about the environmental conditions (Clause 5), to estimate or measure the dynamic conditions (Clause 6) and gives examples to enable decisions to be made on the most applicable environmental vibration test method. Starting from the condition, the method of selecting the appropriate test is given. Since real life vibration conditions are dominated by vibration of a random nature, random testing should be the commonly used method, see Table 1, Clause 7. The methods included hereafter may be used to examine the vibration response of a specimen under test before, during and after vibration testing. The selection for the appropriate excitation method is described in Clause 8 and tabulated in Table 2. In this standard specification, writers will find information concerning vibration test methods and guidance for their selection. For guidance on test parameters, or severities of one of the test methods, reference should be made to the normative references.

IEC 60068-3-4:2001 Provides the necessary information to assist in preparing relevant specifications, such as standards for components or equipment, in order to select appropriate tests and test severities for specific products and, in some cases, specific types of application. The object of damp heat tests is to determine the ability of products to withstand the stresses occurring in a high relative humidity environment, with or without condensation, and with special regard to variations of electrical and mechanical characteristics. Damp heat tests may also be utilized to check the resistance of a specimen to some forms of corrosion attack.

Electrostatics - Part 5-1: Protection of electronic devices from electrostatic phenomena - General requirements

IEC 61340-5-1:2016 is available as IEC 61340-5-1:2016 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 61340-5-1:2016 applies to activities that: manufacture, process, assemble, install, package, label, service, test, inspect, transport or otherwise handle electrical or electronic parts, assemblies and equipment with withstand voltages greater than or equal to 100 V HBM, 200 V CDM and 35 V for isolated conductors. ESDS with lower withstand voltages may require additional control elements or adjusted limits. Processes designed to handle items that have lower ESD withstand voltage(s) can still claim compliance to this standard. This standard provides the requirements for an ESD control program. IEC TR 61340-5-2 [9] provides guidance on the implementation of this standard. This standard does not apply to electrically initiated explosive devices, flammable liquids, gases and powders. The purpose of this standard is to provide the administrative and technical requirements for establishing, implementing and maintaining an ESD control program (hereinafter referred to as the "program"). This edition includes the following significant technical changes with respect to the previous edition:
a) Technical requirements were changed to align IEC 61340-5-1 with other industry ESD standards;
b) Reference documents were updated to reflect newly released IEC standards;
c) A section on product qualification was added;
d) Table 4 was deleted and detailed packaging requirements were deferred to IEC 61340-5-3;
e) Clause A.1 was removed and is now included in IEC 61340-4-6.
The contents of the corrigendum of May 2017 have been included in this copy.
