PAA16, didesnių negu 2 mm makroskopinių priemaišų, temperatūros ir laiko profilių, deguonies vartojimo spartos, savaiminio įkaitimo rodiklio ir likutinio biodujų potencialo nustatymo tręšiamuosiuose produktuose naudojamame komposte ir degazuotajame substrate metodai

This document refers to methods to be used for the determination of specific parameters in compost, fresh crop digestate and digestate other than fresh crop digestate when used as components of fertilizing products, but does not contain the methods themselves. The specific parameters in this document include: — the determination of the PAH16 content; — macroscopic impurities; — the determination of temperature-time profiles during composting and digestion; — oxygen uptake rate; — self-heating factor; — the determination of the residual biogas potential in digestate. This document is applicable to the fertilizing product blends where a blend is a mix of two or more fertilising products belonging to the categories of fertilizers, liming material, soil improvers, growing media, inhibitors and plant biostimulants, and where soil improvers and/or growing media are the components with the highest percentage in the blend by mass or volume, or in the case of products in liquid form by dry mass. If the soil improvers and/or growing media are not the components with the highest percentage in the blend, the European Standard relevant to the component with the highest percentage in the blend applies. In case a blend is composed of fertilising products mixed in equal quantities, the user of the standard decides which standard to apply. NOTE A soil improver or a growing medium consists of a single bulky (volume-building) component or a mix of bulky (volume-building) components (for example peat, wood fibres, coconut coir, compost, expanded perlite).

Pastatų šildymo sistemos. Šildymo sistemų su šilumos siurbliais projektavimas

This document specifies design criteria for heating and cooling systems in buildings using electrically driven heat pumps for heating and cooling alone or in combination with other heat generators. The heat pump systems considered in this document (source system/sink system) are listed in Table 1. For cooling purposes, energy source and energy sink can be reversed. This document also applies to other energy sources such as wastewater, massive absorbers, ice storage systems, as well as heat pump systems using more than one energy source. This document takes into account the heating requirements of attached systems (e.g. domestic hot water) in the design of the heat supply but does not cover the design of these systems. This document covers the aspects dealing with the heat pump, the interface with the heat distribution system and heat emission system, the control of the whole system and the aspects dealing with energy source of the system. Design criteria for reversible heat pump systems for heating and cooling are also included in this document. Table 1 - Heat pump systems used for heating (within the scope)

Sistemų ir programinės įrangos inžinerija. Sistemų ir programinių produktų kokybės reikalavimai ir įvertinimas (SQuaRE). Tinkamumui naudoti skirtas bendras srities formatas (CIF). Naudojimo konteksto aprašas (ISO/DIS 25063:2026)

ISO/IEC 25063:2014 describes the Common Industry Format (CIF) for context of use descriptions and specifies the contents of both high-level and detailed descriptions of the context of use for an existing, intended, implemented or deployed system. A context-of-use description includes information about the users and other stakeholder groups, the characteristics of each user group, the goals of the users, the tasks of the users, and the environment(s) in which the system is used. The context of use description is applicable to software and hardware systems, products or services (excluding generic products, such as a display screen or keyboard). It is important to gather and analyse information on the current context in order to understand and then describe the context that will apply in the future system. The context of use description provides a collection of data relevant for analysis, specification, design and evaluation of an interactive system from the perspective of the various user groups and other stakeholders.

Sveikatos priežiūros gaminių sterilizavimas. Drėgnoji šiluma. Reikalavimai, keliami sterilizatoriams, naudojamiems vandeniniams skysčiams sandariose talpyklose galutinai sterilizuoti (ISO/DIS 19253:2026)

Specifies the requirements and the relevant tests for sterilizers intended to be used for the terminal sterilization of health care products (medical devices or medicinal products) presented as aqueous liquid in sealed containers. The container can be rigid, semi rigid or flexible. The sterilizing agent, moist heat, is created internally from the product, heating being achieved by use of saturated steam, mixtures of steam and a pressure ballasting non-condensing gas such as air or super-heated water in the sterilizer chamber. The sterilizers can be used in both a health care and industrial setting. This standard does not apply to sterilizers using saturated steam for the sterilization of the surfaces of medical devices or sterilizers used in laboratories. NOTE 1 Sterilizers using saturated steam for sterilizing the surfaces of medical devices are covered by EN 285 and EN 13060. Laboratory sterilizers are covered by some national standards. NOTE 2 Sterilizers conforming to NWIP ISO XXXXX can also be used for the sterilization of other aqueous liquid in sealed containers such as veterinary products or some foodstuffs. Note 3 Sterilizers conforming to NWIP ISO XXXXX can also be used for the sterilization of a contained product enclosed within a sterile barrier system conforming to the EN ISO 11607 series of standards.

This document specifies requirements and tests for the construction, performance and safety of class 1,0 and class 1,5 battery powered ultrasonic gas meters (hereinafter referred to as meters), having co-axial single pipe, or two pipe connections, used to measure volumes of distributed fuel gases of the 2nd and/or 3rd family gases as given in EN 437:2021, at maximum working pressures not exceeding 0,5 bar )) and maximum actual flow rates of up to 40 m3/h over a minimum ambient temperature range of −10 °C to +40 °C, and minimum gas temperature span of 40 K. This document applies to meters where the measuring element and the register(s) are enclosed in the same case. This document applies to meters with and without built-in temperature conversion, that are installed in locations with vibration and shocks of low significance and in - closed locations (indoor or outdoor with protection as specified by the manufacturer) with condensing or with non-condensing humidity; or, if specified by the manufacturer; - 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. Unless otherwise stated, all pressures given in this document are gauge pressures. Clauses 1 to 14 are for design and type testing only. Requirements for electronic indexes, batteries, valves incorporated in the meter and 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 intended by the manufacturer. When more than one meter type is submitted for testing, then each meter type needs to be tested against this document.

This document defines the fire resistance test and requirements for landing doors which are intended to provide a barrier to the spread of fire from the landing side and via the lift well in buildings for a period of time classified in this document. The fire resistance requirements are expressed in terms of integrity (E), insulation (EI) and radiation (EW). It is applicable to landing doors installed in the lift well openings at landings and used as means of access to lift car. It also specifies the method of testing and classification of fire resistance of landing doors. The test method is only valid for furnaces where the door is mounted in a vertical position. The test method specifies the measurement of integrity and if required the measurement of radiation and thermal insulation. This document refers to CO2 as means of tracing the propagation of fire. The document does not cover hazards due to emission of gases. This document is not applicable to landing doors which are installed before the date of its publication.
