Household and similar electrical appliances - Safety - Part 2-24: Particular requirements for refrigerating appliances, ice-cream appliances and ice makers

This standard deals with the safety of the following appliances, their rated voltage being not more than 250 V for single-phase appliances, 480 V for other appliances and 24 V DC for appliances when battery-operated: – refrigerating appliances for household and similar use; – ice-makers incorporating a motor-compressor and ice-makers intended to be incorporated in frozen food storage compartments intended for household use; – refrigerating appliances and ice-makers for applications similar to household use such as for camping, in leisure accommodation vehicles, on boats for leisure purposes and on board ships; – mobile refrigerating appliances. These appliances can be operated from the mains, from a separable battery or operated either from the mains or from a separable battery or from other sources of energy (gas, liquid and solid fuel). This standard deals also with refrigerating appliances intended for the use on boats for leisure purposes and on board ships, for which the normative Annex FF is applicable. This standard also deals with the safety of ice-cream appliances intended for household use, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. It also deals with compression-type appliances for household and similar use, which use flammable refrigerants. This standard does not cover features of the construction and operation of those refrigerating appliances which are dealt with in other IEC standards.

Stationary source emissions - Determination of the mass concentration of PCDDs/PCDFs and dioxin-like PCBs - Part 5: Long-term sampling of PCDDs/PCDFs/PCBs

This document specifies the long-term sampling of PCDDs/PCDFs/PCBs. There are three different sampling methods, which are based on the three different principles described in EN 1948-1, but partially modified for long-term sampling requirements: — filter/condenser method; — dilution method; — cooled probe method. Each sampling method is illustrated in detail in Annex D. The sampling methods described in this document are designed for a sampling duration of typically up to four weeks. Additionally, this document specifies a framework of quality control requirements for any long-term sampling method. With the methods described, experiences were gained for a concentration range up to 4,0 ng TEQ/m3 at various stationary sources (e.g. waste incinerators, sinter plants, cement kilns). For complete implementation of the measurement method, the use of EN 1948-2 and EN 1948-3 describing extraction, clean-up, identification, and quantification, respectively, is necessary in order to determine PCDDs/PCDFs. Additionally, EN 1948-4 is necessary for PCBs.

Water quality - Radon-222 - Part 1: General principles (ISO/DIS 13164-1:2026)

This part of ISO 13164 gives general guidelines for sampling, packaging, and transporting of all kinds of water samples, for the measurement of the activity concentration of 222Rn. The test methods fall into two categories: a) direct measurement of the water sample without any transfer of phase (see ISO 13164-2[7]); b) indirect measurement involving the transfer of the 222Rn from the aqueous phase to another phase (see ISO 13164-3[8] and 13164-4[9]). The test methods can be applied either in the laboratory or on-site. The laboratory is responsible for ensuring the suitability of the test method for the water samples tested.

Nuclear fuel technology - Determination of uranium in solutions, uranium hexafluoride and solids - Part 2: Iron(II) reduction/cerium(IV) oxidation titrimetric method (ISO 7097-2:2022)

This document describes an analytical method for the determination of uranium in samples from pure product materials such as U metal, UO2, UO3, U3O8, uranyl nitrate hexahydrate and uranium hexafluoride from the nuclear fuel cycle. This procedure is sufficiently accurate and precise to be used for nuclear materials accountability. This method can be used directly for the analysis of most uranium and uranium oxide nuclear reactor fuels, either irradiated or un-irradiated, and of uranium nitrate product solutions. Fission products equivalent to up to 10 % burn-up of heavy atoms do not interfere, and other elements which could cause interference are not normally present in sufficient quantity to affect the result significantly. The method recommends that an aliquot of sample is weighed and that a mass titration is used, in order to obtain improved precision and accuracy. This does not preclude the use of alternative techniques which could give equivalent performance. The use of automatic device(s) in the performance of some critical steps of the method has some advantages, mainly in the case of routine analysis.

Agricultural and forestry machinery – Combined firewood processors - Safety

This document specifies safety requirements and their verification for the design and construction of firewood processors, designed to be used for making firewood. Firewood processors are combined machinery that cut and then split the wood. This document covers machines where the cutting is done either by a chain blade or a circular saw, and splitting movement is done horizontally or near horizontally by one or more splitting wedges. If cutting or splitting is done by other means, e.g. by guillotine blade or vertical movement splitting, this document is not applicable. This document is not applicable for machinery, where the wood is required to be moved from cutting to the splitting by manual handing by the operator. This document deals with firewood processors that are designed in a way that only one operator carries out the work process, but it is foreseeable that other operators, e.g. for loading or unloading, will work on or close to the machine. This document deals with all significant hazards, hazardous situations and hazardous events relevant to these machines, when they are used as intended and under the conditions foreseen by the manufacturer. See Clause 4 for the list of significant hazards. This document is not applicable to machines which were manufactured before the date of its publication. This document is applicable for manually operated, semi-automatic and automatic firewood processors. This document is applicable to the following possible integral features of the firewood processor: - Integral outfeed conveyors - Integral infeed conveyors - Integral hold to run operated log lifting device Other accessories or added features of firewood processors are not covered by this document. These could be e.g.: - Separate conveyors or tables that are not integral parts of the machine - Other wood lifting equipment (e.g. winch or crane) - Other separate accessories of the machine, e.g. for cleaning the wood or packing the wood.

Fume cupboards — Part 9: Fume cupboards, ducted with filtered internal recirculation

This document specifies characteristics concerning the design and performance requirements together with type testing and on-site testing procedures especially for ducted filtration fume cupboards (DFFCs) not described in the other parts of EN 14175. Filters in DFFCs can be specific filters or a combination of filters dependent on the characteristics of the contaminants to be removed. This part of EN 14175 is related to and refers to other parts of EN 14175 regarding definitions, technologies, testing methodologies, design factors and functional aspects and is read in conjunction with these. This standard covers the specific layout version of ducted fume cupboards with integral filtration. These devices called ducted filtration fume cupboards can be designed to partially reuse filtered air for internal dilution. Therefore, the term “hybrid” fume cupboards is sometimes used. Fume cupboards with associated filters are considered as standard fume cupboards according EN 14175 1 to EN 14175 3. NOTE Their filter requirements, description and testing are listed in Annex A for information. The requirements for fume cupboards and filters for radioactive work are described in detail in EN 14175 8. Recirculatory filtration fume cabinets which return the filtered exhaust air back into the surrounding room are not part of this document but described in prEN 17242. DFFCs are not foreseen for work with pathogens. Appropriate microbiological cabinets are described in the EN 12469 series.
