Biological durability of wood and wood-based products - Quantitative determination of pentachlorophenol in wood - Gas chromatographic method

This document specifies a laboratory method of determining the pentachlorophenol content of wood. The method is applicable to all types of pentachlorophenol (PCP) in woods and wood-based materials as well as for the analysis of waste timber with respect to its pentachlorophenol (PCP) content. The method described has a measurement range from 250 µg/kg up to pentachlorophenol (PCP) contents of 5 mg/kg of dry matter. These figures refer to the given example (where an aliquot of 1 ml of the extract is used for acetylation, see 9.3). NOTE 1 If lower quantification limits are required, a higher volume of extract aliquot can be used for derivatisation. NOTE 2 This method could have some modifications with some wood species as hardwoods. In general, in the case of complex matrix, a method using mass spectrometry can be used.

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]).

Energy performance of buildings - Method for calculation of system energy requirements and system efficiencies - Part 7-1: DHW instantaneous heat recovery- Module M8-13

This calculation module applies to instantaneous domestic hot water heat recovery using a counter-flow heat exchanger between the drain water and the incoming domestic cold water. This module calculates the recovered heat, to be taken into account in the overall calculation procedure of the energy performance of the building. The scope of this document is to standardize the: - required inputs; - calculation methods; - required outputs; of the instantaneous heat recovery from domestic hot water drains. This document provides a calculation method for one calculation interval. This calculation is intended to be connected to the whole building calculation model and takes into account the external conditions and system controls that may influence the instantaneous heat recovery from domestic hot water drains. This document does not apply to storage heat recovery or the use of drain water as a source for heat pumps. This document does not apply to sizing or inspection of domestic hot water heat recovery devices. Table 1 shows the relative position of this document within the set of EPB standards in the context of the modular structure as set out in EN ISO 52000-1. NOTE 1 The same Table is found in CEN ISO/TR 52000-2, with, for each module, the numbers of the relevant EPB standards and accompanying technical reports that are published or in preparation. NOTE 2 The modules represent EPB standards, although one EPB standard might cover more than one module and one module might be covered by more than one EPB standard, for instance a simplified and a detailed method respectively. See also Clause 2 and Table A.1 and Table B.1.

Nuclear energy - Determination of neutron fluence and displacement per atom (dpa) in reactor vessel and internals (ISO/DIS 19226:2026)

ISO 19226:2017 provides a procedure for the evaluation of irradiation data in the region between the reactor core and the inside surface of the containment vessel, through the pressure vessel and the reactor cavity, between the ends of active fuel assemblies, given the neutron source in the core. NOTE These irradiation data could be neutron fluence or displacements per atom (dpa), and Helium production. The evaluation employs both neutron flux computations and measurement data from in-vessel and cavity dosimetry, as appropriate. This document applies to pressurized water reactors (PWRs), boiling water reactors (BWRs), and pressurized heavy water reactors (PHWRs). ISO 19226:2017 also provides a procedure for evaluating neutron damage properties at the reactor pressure vessel and internal components of PWRs, BWRs, and PHWRs. Damage properties are focused on atomic displacement damage caused by direct displacements of atoms due to collisions with neutrons and indirect damage caused by gas production, both of which are strongly dependent on the neutron energy spectrum. Therefore, for a given neutron fluence and neutron energy spectrum, calculations of the total accumulated number of atomic displacements are important data to be used for reactor life management.

Sterile single-use syringes, with or without needle, for insulin (ISO/DIS 8537:2025)

ISO 8537:2016 specifies requirements and test methods for empty, sterile, single-use syringes, with or without needles, made of plastic materials and intended solely for the injection of insulin, with which the syringes are filled by the end user. This International Standard covers syringes intended for single-use only in humans and with insulins of various concentrations. The insulin syringes specified in this International Standard are intended for use (i.e. insulin injection) immediately after filling and are not intended to contain insulin for extended periods of time. ISO 8537:2016 excludes single-use syringes made of glass, syringes for use with power-driven syringe pumps, syringes that are pre-filled by the manufacturer, and syringes intended to be stored after filling (e.g. in a kit intended for filling by a pharmacist).
