Guidelines for principal component reliability testing for LED light sources and LED luminaires

Published by: 2017-03-03 / 2017-03-03 / 65 pages
IEC TS 62861:2017(E) This Technical Specification provides guidelines for establishing confidence in product reliability using principal component testing for LED light sources and LED luminaires for general lighting. It includes methods and criteria using initial qualification tests and accelerated stress tests of the principal components. The performance of any principal component will influence the performance of the final product.
Techniques to validate full lifetime claims and lumen maintenance projection are outside the scope of this Technical Specification. The following principal components are included in the testing if they are used as an integral part for the LED light source or LED luminaire:
– LED package and interconnects;
– optical materials;
– electronic subassemblies;
– cooling systems, both active (e.g. fans) and passive (e.g. thermal interface material);
– construction materials.
This Technical Specification is not recommended for use as a normative reference to the LED product performance standards.

Nanomanufacturing – Key control characteristics – Part 4-5: Cathode nanomaterials for nano-enabled electrical energy storage – Electrochemical characterization, 3-electrode cell method<br />

Published by: 2017-01-12 / 2017-01-12 / 22 pages
IEC TS 62607-4-5:2017(E) provides a standardized method for the determination of electrochemical properties of cathode nanomaterials such as lithium iron phosphate (LFP) for electrical energy storage devices. This method will enable the industry to:

  1. decide whether or not a cathode nanomaterial is usable, and
  2. select a cathode nanomaterial suitable for their application.

This document includes:

  • recommendations for sample preparation,
  • outlines of the experimental procedures used to measure cathode nanomaterial properties,
  • methods of interpretation of results and discussion of data analysis, and
  • case studies.

NOTE The very purpose of this method is to arrive at a detailed characterization of the electrodes so that individual contribution of the anode and cathode for performance and degradation could be predicted. The method can be applied for characterization of the electrode working as cathode or/and as anode.
