Dujų skaitikliai. Šiluminio masės srauto matuoklio principu veikiantys dujų skaitikliai

This document specifies requirements and tests for the construction, performance, safety and production of battery powered class 1,5 Capillary Thermal-Mass Flow sensor gas meters (hereinafter referred to as meter(s)). This applies to meters having co-axial single pipe, or two pipe connections, which are used to measure volumes of fuel gases of the 2nd and/or 3rd family, as given in EN 437:2021. In general, the term "thermal mass flow meters" applies to a flow-measuring device using heat transfer to measure and indicate gas flowrate, as defined in ISO 14511. NOTE Although the word "mass" is present in the definition of the measurement principle, gas meters covered by this document provide measurement of gas at base conditions of temperature and pressure. These meters have a maximum working pressure not exceeding 0,5 bar and a maximum flowrate not exceeding 160 m3/h over a minimum ambient temperature range of −10 °C to +40 °C and a gas temperature range as specified in the marking, with a minimum range of 40 °C. For meters designed for hydrogen measurement, the maximum flowrate is not exceeding 480 m3/h, whilst the other characteristics are as stated above. This document applies to meters indicating volume at base conditions, which are installed in locations with vibration and shocks of low significance. It applies to meters in: - closed locations (indoor or outdoor with protection, as specified in the instruction manual) with condensing humidity or with non-condensing humidity; or, if specified in the marking: - open locations (outdoor without any covering) both with condensing humidity or with non-condensing humidity; and in locations with electromagnetic disturbances likely to be found in residential, commercial and light industrial use. For meters which indicate unconverted volume, reference can be made to Annex C. Unless otherwise stated, all pressures given in this document are gauge pressures. Requirements for electronic indexes, valves and additional requirements for batteries incorporated in the meter and any other additional functionalities are given in EN 16314:2013. Unless otherwise stated in a particular test, the tests are carried out on meters that include additional functionality devices, as indicated in the instruction manual. Clauses 1 to 13 are for design and type testing only. For meters designed for blended gas and/or hydrogen measurement, refer to Annex E. This document refers only to hydrogen as specified in ISO 14687:2025 with a purity of type I grade A or better. Unless otherwise stated, all tests applicable to 2nd and 3rd family gases are applicable also to blended gas and hydrogen. Mixtures with a hydrogen concentration above 20 % and below 98 % by volume are not covered by this document.

Buitiniai ir panašios paskirties elektriniai prietaisai. Sauga. Ypatingieji reikalavimai, keliami komercinėms elektrinėms konvejerinėms indaplovėms

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”.

This document is applicable for internally coated cylindrical and conical aluminium tubes, mainly used for the packing of pharmaceutical, cosmetic, hygiene, food or other household products. The internal coating is used as a barrier to avoid any contact between aluminium and the product. This document defines the sodium chloride method to detect the electrolyte conductivity as one criterion for the quality of the internal coating. NOTE The electrolyte conductivity of the internal coating is only one criterion for evaluation of the quality of an internal coating. It does not give any information on the quantity or size of any pores or uncoated areas, nor any hint on possible reactions between the aluminium tube and the product. The electrolyte conductivity can never be used as the sole criterion for quality evaluation of the internal coating, but always with other parameters e.g. film thickness, acetone and/or ammonia resistance and of course results of enhanced stability studies.
