IEC 62885-2:2021 is applicable for measurements of the performance of mains-operated dry vacuum cleaners, including water filter vacuum cleaners for household or similar use. The purpose of this document is to specify essential performance characteristics of dry vacuum cleaners which are of interest to users and to describe methods for measuring these characteristics. Due to the influence of environmental conditions, variations in time, origin of test materials and proficiency of the operator, some of the described test methods will give more reliable results when applied for comparative testing of a number of appliances at the same time, in the same laboratory and by the same operator. The methods here can be applied with modifications for surface-cleaning product types or technologies not currently covered within the scope. For safety requirements, reference is made to IEC 60335-1. A recommendation on information for the consumer at the point of sale is given in Annex B. This second edition of IEC 62885-2 cancels and replaces the first edition published in 2016. This edition constitutes a technical revision. This second edition includes the following significant technical changes with respect to the previous edition: a) Inclusion of requirements for water filter vacuum cleaners throughout document b) Clause 4.6 on operation of the dry vacuum cleaner has been revised. c) Add new paragraph 4.11, consolidating test area and stroke length from 5.1.2, 5.3.2, 6.2.2 and 18.104.22.168. Added new 4.12 for stroke speed. d) Added debris pick-up test for hard floor and carpet. Includes new Annex E. e) Clause 6.2.2 – Clarification of the carpet to be used; reference 4.11 for test area. Remove restriction limiting carpets to motion resistance only.

IEC TS 62607-6-6:2021(E) establishes a standardized method to determine the structural key control characteristic • strain uniformity for single-layer graphene by • Raman spectroscopy. The width of the 2D-peak in the Raman spectrum is analysed to calculate the strain uniformity parameter which is a figure of merit to quantify the influence of nano-scale strain variations on the electronic properties of the layer. The classification will help manufacturers to classify their material quality to provide an upper limit of the electronic performance of the characterized graphene, to decide whether or not the graphene material quality is potentially suitable for various applications.
