Soil improvers and growing media - Methods for the determination of PAH16, macroscopic impurities above 2mm, the temperature-time profiles, oxygen uptake rate, self-heating factor and residual biogas potential in compost and digestate when used in fertilizing products

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).

Heating systems in buildings - Design of heat pump heating systems

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)

Systems and software engineering - Systems and software product Quality Requirements and Evaluation (SQuaRE) - Common Industry Format (CIF) for usability: Context of use description (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.

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.

Organic and organo-mineral fertilizers - Determination of the total content of specific elements by ICP-AES after digestion by aqua regia

This document specifies a method for the determination of arsenic (As), cadmium (Cd), copper (Cu), chromium (Cr), lead (Pb), nickel (Ni)), boron (B), cobalt (Co), iron (Fe), manganese (Mn), molybdenum (Mo), zinc (Zn), phosphorus (P), potassium (K), magnesium (Mg), calcium (Ca), sulfur (S) and sodium (Na) in aqua regia digests of organic, organo-mineral fertilizers, and their fertilizing product blends using inductively coupled plasma-atomic emission spectrometry (ICP-AES). It is applicable and validated for several types of matrices as indicated in Annex A. This document is applicable to the component materials “by-products”, when used as components of fertilizing products, as well as the fertilizing products blends where a blend is a mix of at least two of the following components: fertilizers, liming materials, soil improvers, growing media, inhibitors, plant biostimulants, and where the following category: organic fertilizers, organo-mineral fertilizers is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If the organic fertilizer or the organo-mineral 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. This method is applicable to aqua regia digests prepared according to prEN 17768. NOTE Alternatively, inductively coupled plasma mass spectrometry (ICP-MS) can be used for the determination of the elements in the aqua regia digests if the user proves that the method gives the same results.

Road and airfield surface characteristics - Test methods - Part 4: Method for measurement of slip/skid resistance of a surface: The pendulum test

This document describes a method for determining the slip/skid resistance of a surface using a device which remains stationary at the test location. The slip/skid resistance is measured by means of a slider mounted at the end of a pendulum arm. The method provides a measure of the slip/skid resistance properties of a wetted surface either in the field or in the laboratory. This method measures the slip/skid resistance of a small area of a surface (approximately 0,01 m2). It is important to consider this when deciding its applicability to a surface which might have nonhomogeneous surface characteristics, e.g. containing ridges or grooves, or is rough textured (exceeding 1,5 mm mean texture depth).
