IEC 62885-8:2019 pdf download.Surface cleaning appliances – Part 8: Dry vacuum cleaners for commercial use – Methods for measuring the performance
1 Scope
Replace the scope of IEC 62885-2:2016 by the following: This part of IEC 62885 is applicable for measurements of the performance of mains-operated dry vacuum cleaners, including water filter vacuum cleaners, for commercial use. The requirements for the construction and testing covered by this document are applied in addition to the requirements for commercial vacuum cleaners in IEC 60335-2-69. The purpose of this document is to specify essential performance characteristics of dry vacuum cleaners for commercial use that are of interest to operators and to describe methods for measuring these characteristics. NOTE 1 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. NOTE 2 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 and IEC 60335-2-69.
4 General conditions for testing
This clause of IEC 62885-2:201 6 is applicable with the following modifications: 4.6 Operation of the dry vacuum cleaner 4.6.1 General Replace the content of 4.6.1 by the following: The tube grip of cleaners with suction hose or the handle of other cleaners shall be held at a height of (800 ± 50) mm above the test surface. For nozzles without pivoting connectors, it shall be ensured that the bottom of the cleaning head be made parallel with the test surface by adjusting the handle height within the tolerances. If this is not possible, the length of a telescopic tube may be adjusted. Any adjustment shall be reported. During measurements where the agitation device of an active nozzle is not used as in normal operation, the agitation device shall be running but not in contact with any surface. The following wording regarding declaration and compliance shall also apply to IEC 60335-2-69: “For declaration and compliance purposes, related tests conducted on a surface type (carpet or hard surface with or without crevice) shall be conducted with the same dry vacuum cleaner setting configurations such as power, cleaning head and cleaning head setting.”The dry vacuum cleaner setting configurations, such as cleaning head and cleaning head setting, shall be used and adjusted in accordance with the manufacturer’s instructions for the surface to be cleaned (e.g. carpet or hard floor) for the test to be carried out. Any electrical controls shall be set for maximum continuous airflow for the floor surface setting and, unless the manufacturer’s instructions state otherwise, any manually operated air by-pass opening for reduction of the suction power shall be closed. A boost function on the vacuum cleaner, changing the normal operation mode as stated by the manufacturer, is not activated during any measurement. The maximum operational power including the boost function shall not exceed the result from the rated input power measurement as declared by the manufacturer, in accordance with IEC 60335-2-69. Motion resistance, as determined in 6.2, shall not be larger than 40 N for operating the commercial dry vacuum cleaner to determine its performance. NOTE 1 A motion resistance of maximum 40 N is seen as acceptable for application in a professional environment. Higher motion resistance contradicts continuous duty in a professional environment owing to the large force to be applied by the operator during usage, which contradicts the applicability. In the absence of unambiguous instructions within the manufacturer’s instructions, the product shall be tested with settings that are in accordance with any explicitly clear text, symbol or pictogram that is identifiable on the product.
