Environmental testing - Part 2-82: Tests - Test XW1: Whisker test methods for components and parts used in electronic assemblies
This part of IEC 60068 specifies tests for the whiskering propensity of surface finishes of electric or electronic components and mechanical parts such as punched/stamped parts (for example, jumpers, electrostatic discharge protection shields, mechanical fixations, press-fit pins and other mechanical parts used in electronic assemblies) representing the finished stage, with tin or tin-alloy finish. Changes of the physical dimensions of mould compounds, plastics and the like during the required test flow are not considered or assessed. The test methods have been developed by using a knowledge-based approach. This document can also be used at sub-suppliers, like plating shops, stamping shops or other service providers to ensure a consistent surface quality within the supply chain. These test methods are employed with defined acceptance criteria by a relevant component or application specification. The tests described in this document are applicable for initial qualification, for periodic monitoring in accordance with Clause 7, and for changes of technology or manufacturing processes of existing surfaces in accordance with Clause 9. The mating area of connectors is not covered by this test method. IEC 60512-16-21 applies for the mating areas of connectors.

Determination of particle density by sedimentation methods -- Part 2: Multi-velocity approach
This document specifies an in situ method for the determination of the density of solid particles or liquid droplets (herein referred to as "particle") dispersed in liquid continuous phase. The method is based on direct experimental determination of particle velocity in these liquids or media in gravitational or centrifugal fields based on Stokes law. The particle density is calculated from experimentally determined particle velocities in different liquids or media, taking into account their dynamic viscosities and densities, respectively. The approach does not require the knowledge of particle size distribution but assumes that sedimentation relevant characteristics (e.g. volume, shape, agglomeration state) do not change. This document does not consider polydispersity with regard to particle density, i.e. all particles are assumed to be of the same material composition.

IEC 61207-3:2019 RLV

Gas Analyzers - Expression of performance - Part 3: Paramagnetic oxygen analysers
IEC 61207-3:2019 RLV contains both the official IEC International Standard and its Redline version. The Redline version is not an official document, it is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.
IEC 61207-3:2019 applies to the three main methods for measuring oxygen by its paramagnetic property, which are outlined in the introduction. It considers essential ancillary units and applies to analyzers installed indoors and outdoors. Safety-critical applications can require additional requirements from system and analyzer specifications not covered in this document. This document is intended: – to specify terminology and definitions related to the functional performance of para¬magnetic gas analyzers for the measurement of oxygen in a source gas; – to unify methods used in making and verifying statements on the functional performance of such analyzers; – to specify what tests are performed to determine the functional performance and how such tests are carried out; – to provide basic documents to support the application of internationally recognized quality management standards. This third edition cancels and replaces the second edition published in 2002. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) all references (normative and informative) have been updated, deleted or added to as appropriate; b) all the terms, descriptions and definitions relating to the document have been updated where appropriate; c) all references to “errors” have been replaced by “uncertainties” and appropriate updated definitions applied.

Environmental testing - Part 2-67: Tests - Test Cy: Damp heat, steady state, accelerated test primarily intended for components
IEC 60068-2-67:1995+A1:2019 provides a standard test procedure for the purpose of evaluating, in an accelerated manner, the resistance of small electrotechnical products, primarily non-hermetically sealed components, to the deteriorative effect of damp heat. The test is not intended to evaluate external effects such as corrosion and deformation. It has the status of a horizontal standard in accordance with IEC Guide 104. This consolidated version consists of the first edition (1995) and its amendment 1 (2019). Therefore, no need to order amendment in addition to this publication.

Environmental testing -- Part 2-82: Tests - Test Tx: Whisker test methods for electronic and electric components
This part of IEC 60068 specifies whisker tests for electric or electronic components representing the finished stage, with tin or tin-alloy finish. However, the standard does not specify tests for whiskers that may grow as a result of external mechanical stress. This test method is employed by a relevant specification (international component or application specification) with transfer of the test severities to be applied and with defined acceptance criteria. Where tests described in this standard are considered for other components, e.g. Mechanical parts as used in electrical or electronic equipment, it should be ensured that the material system and whisker growth mechanisms are comparable.
