Household and similar electrical appliances - Safety - Particular requirements for commercial electric conveyor dishwashing machines

This clause of Part 1 is replaced with the following. This document deals with the safety of electrically operated commercial conveyor dishwashing machines for washing dishes, glassware, cutlery and similar reusable articles, with or without means for water heating or drying, not intended for household and similar purposes, their rated voltage being not more than 250 V for single-phase appliances connected between one phase and neutral and 480 V for other appliances. These conveyor dishwashing machines are designed to be connected to hot and/or cold water supply. Dishwashing machines making use of steam or hot water for heating purposes are also within the scope of this document. These appliances are used by experts or instructed persons for commercial dishwashing in areas not open to the public, for example in kitchens of restaurants, canteens, hospitals, and in commercial enterprises such as bakeries and butcheries. NOTE 101 Examples of such appliances are: — flight conveyor dishwashing machine; — rack conveyor dishwashing machine. Requirements to avoid backsiphonage of non-potable water into the water mains are specified in Annex BB. This document deals with specific requirements on noise emitted from these appliances because the generated noise can be LpA > 70 dB(A) and is considered to be a relevant hazard. See Clause 7.12.104, 22.115 and Annex CC. The electrical part of appliances making use of other forms of energy is also within the scope of this document. This document deals with the reasonably foreseeable hazards presented by appliances that are encountered by all persons in and around the installation place or workplace. NOTE 102 Attention is drawn to the fact that: — for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements can be necessary; — in many countries, additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities; — in many countries, additional requirements are specified for appliances incorporating pressurized parts; — for scrapping of appliances, additional requirements can be necessary. This document does not apply to: — commercial electric dishwashing machines under EN IEC 60335 2 58; — appliances designed exclusively for industrial purposes, for example machines used in the food industry for cleaning receptacles that serve as packaging for final products (e.g. bottle-cleaning machines) and machines used in manufacturing processes; — gas heated appliances which are part of the conveyor dishwashing machines; — movable appliances; — dishwashing machines that do not form one functional unit, for example where a transportation device transfers the load from one separate unit to another; — separately driven transport devices not confined in the appliance; — appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas); — sterilizers and washer-disinfectors used to treat medical materials (EN IEC 61010 2 040). With this European revision 2.0 of the document, the EN 50416:2005 is superseded. This European revision 2.0 of the document, supplements or modifies the corresponding clauses of the standards below: — EN IEC 60335 1:2023+A11:2023+prA12:2026. Secretary’s note: The above addition has been moved from the Introduction (informative text) to the Scope (normative text) of the standard following discussions with the HAS consultants. According to an EC decision (document GROW.H.3/SM/MH/DT 12/1/2024), Part 1 must be referenced by date in Part 2. Consequently, the standard has been included in Clause 2, “Normative references”.

Water quality - Plutonium and neptunium - Test method using ICP-MS (ISO/DIS 20899:2026)

This document specifies methods to determine the 239Pu, 240Pu, 241Pu and 237Np by inductively coupled plasma mass spectrometry (ICP-MS). The mass concentrations obtained can be converted into activity concentrations. Due to its relatively short half-life and 238U isobaric interference, 238Pu can hardly be measured by this method. To quantify 238Pu isotope by mass spectrometry, other techniques can be used (ICP-MS with collision-reaction cell, ICP-MS/MS with collision-reaction cell or chemical separation). Alpha spectrometry measurement, as described in ISO 13167,[8] is currently used[9]. The method is applicable to test samples of supply/drinking water, rainwater, surface and ground water, marine water, as well as cooling water, industrial water, domestic, and industrial wastewater after proper sampling and handling, and test sample preparation. A chemical separation of Np and Pu, with quantitative removal of all other elements (including uranium, americium, etc.) is mandatory, given all the potential interferences that may bias the measurement or lead to false positives. Chemical separations can eliminate most of the 238U. However, use of reagents, glassware, and atmosphere for the chemical separation, will also add 238U to the samples and prevent measurement of 238Pu. The limit of detection depends on the sample volume, the instrument used, the background count rate, the detection efficiency, the counting time, and the chemical yield. The detection limit of the method described in this document, using currently available ICP-MS apparatus, is approximately 1 mBq·l-1 for 239Pu, 240Pu, 237Np and 1 Bq·l-1 for 241Pu, which is lower or of the same order of magnitude than the WHO criteria for safe consumption of drinking water (1 mBq·l-1 for 239Pu, 240Pu, 237Np and 10 Bq·l-1 for 241Pu[4]).This method covers the measurement of those radionuclides in water at activity concentrations between approximately[10][11]: — 1 mBq·l−1 to 5 Bq·l−1 for 239Pu, 240Pu and 237Np; — 1 Bq·l−1 to 5 Bq·l−1 for 241Pu. Samples with higher activity concentrations than 5 Bq·l−1 can be measured if a dilution is performed. The higher is the concentration factor, the lower are the LD and LQ expressed in Bq/L of water. A preconcentration is especially useful for the quantification of 241Pu that is usually the less abundant isotope of plutonium. The method described in this document is applicable in the event of an emergency situation. Filtration of the test sample is necessary. The analysis of 239Pu, 240Pu, 241Pu and 237Np adsorbed to suspended matter is not covered by this method. The analysis of the insoluble fraction requires a mineralization step that is not covered by this document. In this case, the measurement is performed separately on each phase or the total phase. It is the user’s responsibility to ensure the validity of this test method for the water samples tested.
