Chimneys - Thermal and fluid dynamic calculation methods - Part 2: Chimneys serving more than one combustion appliance

This document specifies methods for calculation of the thermal and fluid dynamic characteristics of chimneys serving more than one combustion appliance. This part of prEN 13384 covers the following cases: a) where the chimney is connected with more than one connecting flue pipe from individual or several combustion appliances in a multi-inlet arrangement; b) where the chimney is connected with an individual connecting flue pipe connecting more than one combustion appliance in a cascade arrangement; or c) where the balanced flue chimney consists of a collective air supply duct serving the combustion air to more than one combustion appliance. Each combustion appliance is connected to an individual flue duct located inside the collective air supply duct to the outlet. Every individual flue duct has a temperature class not exceeding T120, a pressure class of P1, M1 or H1 and a sootfire class of O. The case of multiple inlet cascade arrangement is covered by the case a). This part of prEN 13384 deals with chimneys operating under negative pressure conditions (there can be positive pressure condition in the connecting flue pipe) and with chimneys operating under positive pressure conditions and is valid for chimneys serving combustion appliances for liquid, gaseous and solid fuels. For positive pressure chimneys (case a), b) and c)) this part only applies if any combustion appliance which is out of action can be positively isolated to prevent flue gas back flow. This part of EN 13384 does not apply to: - chimneys with different thermal resistance or different cross-section in the various chimney segments. This part does not apply to calculate energy gain; - chimneys with open fire places, e.g. open fire chimneys or chimney inlets which are normally intended to operate open to the room; - chimneys which serve different kinds of combustion appliances regarding natural draught, fan assisted, forced draught or combustion engine. Fan assisted combustion appliances with draught diverter between the fan and the chimney are considered as natural draught combustion appliances; - chimneys with multiple inlets from more than 5 storeys. (This does not apply to balanced flue chimney.); - chimneys serving combustion appliances with open air supply through ventilation openings or air supply ducts, which are not installed in the same air supply pressure region (e.g. same side of building).

Inorganic fertilizers - Determination of the organic carbon content by dry combustion

This document specifies a method for the determination of total organic carbon content by elemental analysis using dry combustion. The method is applicable to inorganic fertilizers containing more than 0,1 % carbon expressed on dry mass. NOTE This method can also be applied to other types of fertilizers, provided the user has verified the applicability. This document is applicable to the fertilizing products blends where a blend is a mix of at least two of the following components: inorganic fertilizers, organic fertilizers, organo-mineral fertilizers, liming materials, soil improvers, growing media, inhibitors, plant biostimulants and where the following category: inorganic fertilizer is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If inorganic fertilizer is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed of components in equal quantity, the user decides which standard to apply. Variations in analytical methods for fertilizing product blends can lead to differing results as some components or matrix interactions can affect the outcome. Validation procedures have shown that developed standard methods are robust and reliable across diverse product compositions, but possible interferences and unexpected results when analysing fertilizing product blends are possible.

Additive manufacturing - Qualification principles - Part 1: Common failure modes used for process risk mapping (ISO/ASTM DIS 52954-1:2026)

This document identifies common failure modes, which can occur within operations across additive manufacturing (AM) process categories defined in ISO/ASTM 52900. It lists state-of-the-art failure modes, which can lead to risks within AM parts and equipment, as well as providing informative examples of corresponding failure effects and mitigation actions. This document can be used to aid manufacturers in their risk management. While doing so it supports the implementation of AM as a production method within critical applications and regulated industries. This document helps to address the requirements for risk management set by regulated industries for part and production method compliance. Technology specific failure modes will be addressed in separate standards, including but not limited to PBF-LB/M, PBF-LB/P, MEX, MJT, BJT, and DED. This document aims to close the existing gap between general risk management standards, such as ISO 31000 or ISO 14971 (medical), and the know-how gap of existing failure modes of the AM process category and their integrated workflow. The standard maps risks according to AM processes defined within ISO/ASTM 52920. This document does not cover environment, health and safety risks and will not measure, assess, or evaluate the risk impact on the AM part to be produced. It does not list the part specific input and output parameters, during the respective process steps. This task is dedicated to the risk management evaluation teams, which usually comprise quality managers and product domain specific experts. The document enables all part owners and manufacturers to use it for the risk mapping activities, to support subsequent risk assessments, continuous improvement, validation planning, estimation of manufacturing efforts, and conformity audits. For risk examples that are relevant only to specific AM machinery brands, manufacturers might consider use of the informative annex.

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.

Plastics — Intrinsic biodegradability — Criteria and test methods

This document defines test methods and criteria for distinguishing intrinsically biodegradable plastic materials from those that are persistent. Biodegradability is inferred from biodegradation tests conducted under aerobic conditions, i.e. under the conditions typically found in most natural habitats. Plastics that undergo ultimate biodegradation under aerobic conditions in a manner similar to natural polymer materials are defined as biodegradable plastics. This document describes a method for distinguishing between non-biodegradable plastics, which do not biodegrade even when environmental conditions are favourable for biodegradation (including aerobic conditions), and biodegradable plastics, i.e. those that biodegrade upon contact with active microorganisms when environmental conditions are favourable for biodegradation. The aim is to demonstrate ultimate aerobic biodegradability of plastic materials, i.e. the intrinsic potential for conversion to carbon dioxide, water and biomass by aerobic microorganisms in an oxygen-rich environment, which is representative of most natural environments. The potential for biodegradation should be verified using alternative tests and criteria, if a deposition in a permanent anaerobic environment (e.g. deep subsurface environments, wetlands and swamps, anoxic zones in oceans and lakes) is expected. NOTE Currently, there are no methodologies or criteria available to verify accumulation due to the lack of biodegradation of plastics in such anaerobic habitats. The plastic materials identified as intrinsically biodegradable following this document can be used in the design of products with a high risk of dispersion whenever the use of biodegradable components is searched by the designer. Intrinsically non-biodegradable components are not susceptible to biodegradation and therefore cannot be removed from the environment by the action of micro-organisms. This factor tends to increase the residence time of products in the environment. In addition, their eventual degradation, mainly due to abiotic factors, results in persistent fragments (microplastics). The test scheme described in this document is not specific to any particular application. Rather, it is a framework methodology that can be used in different industries to identify biodegradable plastics that can be used to make different types of products and for different applications. For the characterisation and environmental assessment of products placed on the market containing plastics identified as biodegradable according to this document, reference is made to the specific product standards, where available. This document only deals with the definition of intrinsic biodegradability of plastic materials, without defining the hazard of the products, which requires a specific assessment that is beyond the scope of this document. The rate of biodegradation of a plastic object as a function of environmental conditions cannot be determined from this document. Therefore, this document is not sufficient to carry out an analysis of the ecological risk associated with the dispersal of products, as this requires an assessment of the intrinsic hazard, of the environmental fate, in addition to the assessment of biodegradability. The methodology described in this document does not apply to applications covered by mandatory regulations.
