Efficiency of domestic electrical storage water heaters and testing methods

This European Standard specifies methods for measuring the performance of electric storage water heaters for the production of sanitary hot water for household and similar use. The object is to state and define the principal performance characteristics of electric storage water heaters and to describe the test methods for measuring these characteristics. NOTE 1 This standard does not apply to; − storage water heaters that use electricity as a secondary source of heating the water; − storage water heaters that do not use a tank to store hot water; − electric storage water heaters that do not meet the minimum (or maximum) output performance of the smallest (or biggest) load profile, as defined in Table 4. NOTE 2 This standard does not specify performance or safety requirements. For safety requirements see EN 60335-1:2020 in conjunction with EN 60335-2-21:2023

Inorganic fertilizers - Titrimetric determination of ammoniacal nitrogen

This document specifies a method for the titrimetric determination of the ammoniacal nitrogen content in inorganic fertilizers (including compound fertilizers), in which nitrogen is found exclusively either in the form of ammonium salts or ammonium salts together with nitrates. 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 fertilizers are 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. In the case of application to ammonium nitrate fertilizers of high nitrogen content, this document is not applicable to fertilizer product blends. This document is not applicable to fertilizers or fertilizer product blends containing urea, cyanamide, nutrient polymers or other organic nitrogenous compounds.

ISO 17879:2017 specifies the design, type testing, marking and manufacturing tests and examinations requirements for self-closing cylinder valves intended to be fitted to refillable transportable gas cylinders which convey compressed, liquefied or dissolved gases. NOTE 1 The main applications for such self-closing cylinder valves are in the calibration gas and beverage industries. ISO 17879:2017 covers the function of a self-closing cylinder valve as a closure. NOTE 2 Requirements for standard cylinder valves are given in ISO 10297. Requirements for quick-release cylinder valves are given in ISO 17871. ISO 17879:2017 is not applicable to self-closing cylinder valves for cryogenic equipment, for portable fire extinguishers, or for liquefied petroleum gas (LPG). NOTE 3 Requirements for valves for cryogenic vessels are specified in ISO 21011 and at a regional level, for example, in EN 1626. Requirements for valves for portable fire extinguishers at a regional level are specified, for example, in EN 3 series. Requirements for self-closing LPG cylinder valves are specified in ISO 14245. NOTE 4 Additional requirements for pressure-relief devices might be specified in international/regional regulations/standards.

ISO 8589 provides general guidance for the design of test rooms intended for the sensory analysis of products. It describes the requirements to set up a test room comprising a testing area, a preparation area, and an office, specifying those that are essential or those that are merely desirable. ISO 8589 is not specific for any product or test type. Although many of the general principles are similar, ISO 8589 does not address test facilities for the specialized examination of products in inspection or in-plant quality-control applications.

Cybersecurity requirements for products with digital elements - Part 1-3: Vulnerability Handling

This standards shall provide specifications applicable to vulnerability handling processes, covering all relevant product categories, to be put in place by manufacturers of the products with digital elements. Those processes shall at least allow to: (a) identify and document vulnerabilities and components contained in the product, including by drawing up a software bill of materials in a commonly used and machinereadable format covering at the very least the top-level dependencies of the product; (b) in relation to the risks posed to the products with digital elements, address and remediate vulnerabilities without delay, including by providing security updates; where technically feasible, new security updates shall be provided separately from functionality updates; (c) apply effective and regular tests and reviews of the security of the product with digital elements; (d) once a security update has been made available, share and publicly disclose information about fixed vulnerabilities, including a description of the vulnerabilities, information allowing users to identify the product with digital elements affected, the impacts of the vulnerabilities, their severity and clear and accessible information helping users to remediate the vulnerabilities; in duly justified cases, where manufacturers consider the security risks of publication to outweigh the security benefits, they may delay making public information regarding a fixed vulnerability until after users have been given the possibility to apply the relevant patch; (e) put in place and enforce a policy on coordinated vulnerability disclosure; (f) take measures to facilitate the sharing of information about potential vulnerabilities in their product with digital elements as well as in third party components contained in that product, including by providing a standardised contact address for the reporting of the vulnerabilities discovered in the product with digital elements; (g) provide for mechanisms to securely distribute updates for products with digital elements to ensure that vulnerabilities are fixed or mitigated in a timely manner, and, where applicable for security updates, in an automatic manner; (h) ensure that, where security updates are available to address identified security issues, they are disseminated without delay and, unless otherwise agreed between manufacturer and business user in relation to a tailor-made product with digital elements, free of charge, accompanied by advisory messages providing users with the relevant information, including on potential action to be taken.
