Alarm Systems - Hazard Warning Systems - Part 1: Hazard warning systems for use in residential buildings - System requirements

This document applies to the planning, installation, operation, and maintenance of hazard warning systems (HWS) for use in residential buildings, flats, and rooms with flat-like use. It also specifies basic requirements and provisions for reliable interconnection of safety and security technology with smart home systems or active assisted living (AAL) systems and applications. Furthermore, it describes basic requirements for devices and systems or references to respective standards and specifications. This document does not override or in any way limit existing European standards. Hazard warning systems are used for early warning of persons to avoid or reduce personal injury and damage to property, which can result from intrusion, hold-up, fire, dangerous gases, and water ingress as well as technical defects of building services. HWS can also be used in residential properties in the event of duress/harassment and, for communication with persons in emergency situations who are present in the property covered by the HWS or to initiate controls in building services because of the aforementioned events. HWS can be designed in compliance with this standard as a self-contained system, or as HWS with connection of Smart Home components, or as a HWS that is a Smart Home system with integrated security applications. For the purposes of this document, the term “smart home” includes all networked systems and or web-based technical processes or IoT devices that are used in residential properties. This includes also, for example, remotely controllable devices such as cameras, entertainment electronics, household appliances, heating, air conditioning, ventilation (HVAC), electrical control components, door/gate/window openings and others. For the purposes of this document, AAL systems are assistance systems that support everyday life and are usually used in combination with services to provide needs-based support in the home environment for people with special needs. In most cases, AAL systems are web- or IoT-based. AAL systems and components are tailored to the individual needs of their users and their living environment and are networked with the building technology and security technology (in this case the HWS) for safety reasons to provide the user with the best possible support to make sure they react appropriately and in time to the situation in the event of an emergency. The task of AAL systems often includes recognizing critical health conditions of their users and initiating appropriate measures. For the purposes of this document, the term networking also means any integration of systems into the HWS and in many cases the connection to smart devices (e.g. smartphone, tablet, PC) via the Internet in conjunction with a specific application software (app). This standard can also be applied when systems are connected to the HWS and themselves use a connection to the Internet to outsource functional intelligence and utilize opportunities to automate processes across application areas, which can be either local, remote or a combination. Any notification or change in status of the HWS or its components can optionally be sent to other persons present in the building and/or to other locations/systems (e.g. emergency call centres [ERC]).

Food products - Determination of the total nitrogen content by combustion according to the Dumas principle and calculation of the crude protein content -Part 2: Cereals, pulses and cereal coproducts (ISO/DIS 16634-2:2025)

ISO 16634-2:2016 specifies a method for the determination of the total nitrogen content and the calculation of the crude protein content of cereals, pulses and milled cereal products. This method, like the Kjeldahl method (see References [1] and [6]), does not distinguish between protein nitrogen and non-protein nitrogen. For the calculation of the protein content, various conversion factors are used (see 3.2).

Cleanrooms and associated controlled environments - Part 13: Cleaning of surfaces to achieve defined levels of cleanliness in terms of particle and chemical concentration (ISO/FDIS 14644-13:2025)

ISO 14644-13:2017 gives guidelines for cleaning to a specified degree on cleanroom surfaces, surfaces of equipment in a cleanroom and surfaces of materials in a cleanroom. Under consideration are all surfaces (external or internal) that are of interest. It provides guidance on the assessment of cleaning methods for achieving the required surface cleanliness by particle concentration (SCP) and surface cleanliness by chemical concentration (SCC) classes and which techniques should be considered to achieve these specified levels. The appropriateness of cleaning techniques will make reference to the cleanliness classes and associated test methods found in ISO 14644‑9 and ISO 14644‑10. The following matters of general guidance will be provided: - expected surface cleanliness levels; - suitability of cleaning methods; - compatibility of surfaces with the cleaning technique; - assessment of cleaning appropriateness. The following will be excluded from this document: - classification of cleaning methods; - product produced within a cleanroom; - specific surface-related cleaning methods; - detailed description of cleaning mechanisms, methods and procedures of various cleaning methods; - detailed material characteristics; - description of damage mechanisms by cleaning processes and time-dependent effects; - references to interactive bonding forces between contaminants and surfaces or generation processes that are usually time-dependent and process-dependent; - other characteristics of particles such as electrostatic charge, ionic charges, etc.; - chemical reactions between molecular contaminants and surfaces; - microbiological aspects of surface cleanliness; - radioactive aspects of contamination; - health and safety considerations; - environmental aspects such as waste disposal, emissions, etc.; - selection and use of statistical methods.

Testing of hardened concrete - Part 12: Determination of the carbonation resistance of concrete - Accelerated carbonation method

This document describes a method for evaluating the carbonation resistance of concrete using test conditions that accelerate carbonation. After a defined period of curing and a period of preconditioning, the test is carried out under controlled exposure conditions using an increased level of carbon dioxide. NOTE The test performed under reference conditions takes a minimum of 112 days comprising a minimum age of the specimen prior to curing under water of 28 days, a minimum preconditioning period of 14 days and an exposure period to increased carbon dioxide level of 70 days. This procedure is not a method for the determination of carbonation depths in existing concrete structures.
