Emergency and danger systems - Part 3: Emergency and danger response systems (EDRS) - Risk management file and examples for applications

This document specifies the structure, construction, content and sequence of a technical risk management process and the technical risk management file in accordance with EN 50726-1. It also describes application examples for technical risk management according to EN 50726-1. An emergency and danger response system (EDRS) is used to minimize risks to life and limb. Its purpose is to report, verify and manage emergencies and dangers in order to prevent or limit personal injury. As already mentioned in the scope of application of EN 50726-1, the implementation of the Occupational Safety and Health Act and the subsequent regulations is intended in order to take particular account of the protection objective defined therein (physical integrity). However, this not only includes a risk assessment (e.g. prevention of acts of violence) for employees, but also for everyone in the property. The requirements of the Occupational Safety and Health Act are therefore intended to be observed when creating a safety concept and as part of the technical risk management process. Consequently, particular attention is drawn to paragraphs 5, 6 and 9 of the Occupational Safety and Health Act. Risks to life and limb can include emergencies and dangerous situations that can cause psychological or physical harm to people. As soon as the top management (e.g. operators, entrepreneurs, companies, approving authorities, building authorities, administrations) of a property has identified such risks to life and limb as part of risk management or similar risk assessments and/or independently became aware of them, this falls within the scope of EN 50726-1.

Inorganic fertilizers - Determination of specific micronutrients

This document specifies references to methods for the determination of the content of the following specific micronutrients in inorganic fertilizers: — the total boron content; — the total cobalt content; — the total copper and zinc content; — the total iron content; — the total manganese content; — total molybdenum content; — the water-soluble boron content; — the water-soluble cobalt content; — the water-soluble copper content; — the water-soluble iron content; — the water-soluble manganese content; — the water-soluble molybdenum content; — the water-soluble zinc content; — the sum of declared micronutrients in compound micronutrient fertilizers. This document is applicable to 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: inorganic fertilizers 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. An overview of the references to methods for the determination of the specific micronutrients is given in Table 1.

Soil quality - Procedure for site-specific ecological risk assessment of soil contamination (soil quality TRIAD approach) (ISO/DIS 19204:2026)

ISO 19204:2017 describes in a general way the application of the soil quality TRIAD approach for the site-specific ecological risk assessment of contaminated soils. In detail, it presents in a transparent way three lines of evidence (chemistry, ecotoxicology and ecology) which together allow an efficient, ecologically robust but also practical risk assessment of contaminated soils. This procedure can also be applicable to other stress factors, such as acidification, soil compaction, salinization, loss of soil organic substance, and erosion. However, so far, no experience has been gained with these other applications. Therefore, this document focuses on soils contaminated by chemicals. NOTE 1 This document focuses on ecological risk assessment. Thus, it does not cover human health end points. In view of the nature of this document, the investigation procedure is described on a general level. It does not contain details of technical procedures for the actual assessment. However, this document includes references relating to technical standards (e.g. ISO 15799, ISO 17616) which are useful for the actual performance of the three lines of evidence. In ecological risk assessment, the effects of soil contamination on the ecosystem are related to the intended land use and the requirements that this use sets for properly functioning soil. This document describes the basic steps relating to a coherent tool for a site-specific risk assessment with opportunities to work out site-specific details. ISO 19204:2017 can also be used for the evaluation of clean-up operations, remediation processes or management measures (i.e. for the evaluation of the environmental quality after having performed such actions). NOTE 2 This document starts when it has already been decided that an ecological risk assessment at a given site needs to be performed. In other words, the practical performance of the soil quality TRIAD and the evaluation of the individual test results will be described. Thus, nothing will be said about decisions whether (and if yes, how) the results of the assessment are included in soil management measures or not. NOTE 3 The TRIAD approach can be used for different parts of the environment, but this document focuses mostly on the soil compartment. Comparable documents for other environmental compartments are intended to be prepared in addition (e.g. the terrestrial aboveground compartment) in order to perform a complete site assessment, based on the same principles and processes.

Plastics - Determination of flexural properties (ISO/DIS 178:2026)

This document specifies a method for determining the flexural properties of rigid and semi-rigid plastics under defined conditions. A preferred test specimen is defined, but parameters are included for alternative specimen sizes for use where appropriate. A range of test speeds is included. The method is used to investigate the flexural behaviour of the test specimens and to determine the flexural strength, flexural modulus and other aspects of the flexural stress/strain relationship under the conditions defined. It applies to a freely supported beam, loaded at midspan (three-point loading test). The method is suitable for use with the following range of materials: — thermoplastic moulding, extrusion and casting materials, including filled and reinforced compounds in addition to unfilled types; rigid thermoplastics sheets; — thermosetting moulding materials, including filled and reinforced compounds; thermosetting sheets. In agreement with ISO 10350-1[5] and ISO 10350-2,[6] this document applies to fibre-reinforced compounds with fibre lengths ≤7,5 mm prior to processing. For long-fibre-reinforced materials (laminates) with fibre lengths >7,5 mm, see ISO 14125[7]. The method is not normally suitable for use with rigid cellular materials or sandwich structures containing cellular material. In such cases, ISO 1209-1[3] and/or ISO 1209-2[4] can be used. NOTE 1 For certain types of textile-fibre-reinforced plastic, a four-point bending test is used. This is described in ISO 14125. The method is performed using specimens which can be either moulded to the specified dimensions, machined from the central section of a standard multipurpose test specimen (see ISO 20753) or machined from finished or semi-finished products, such as mouldings, laminates, or extruded or cast sheet. The method specifies the preferred dimensions for the test specimen. Tests which are carried out on specimens of different dimensions, or on specimens which are prepared under different conditions, can produce results which are not comparable. Other factors, such as the test speed and the conditioning of the specimens, can also influence the results. NOTE 2 Especially for injection moulded semi-crystalline polymers, the thickness of the oriented skin layer, which is dependent on the moulding conditions, also affects the flexural properties. The method is not suitable for the determination of design parameters but can be used in materials testing and as a quality control test.
