Darbo vietos oras. Frakcijų granuliometrinės sudėties apbrėžimai ore esančioms dalelėms matuoti

This document specifies sampling conventions for airborne particle size fractions to assess health-related exposure resulting from the inhalation of particles in workplace atmospheres. Conventions are defined for the inhalable, thoracic and respirable fractions. The sampling conventions only describe the inhalation of particles and their penetration in the respiratory tract as governed by inertia (impaction). Exhaled particles and deposition in the respiratory tract by other mechanisms, e.g. diffusion, are not considered in this document. The sampling conventions defined in this document apply to both indoor and outdoor workplaces. The conventions assume particles penetration and only oral breathing as a worst-case scenario. Nevertheless, the conventions are applicable to both oral and nasal breathing. The conventions are defined based on assumptions given in Clause 6. The choice of convention for a specific application depends on the region of the respiratory tract affected by the health impact of the particle component of interest (see Clause 5). The conventions can be applied to various metrics, including particle number, length, surface area, volume, or mass, depending on the type of particle analysis performed on the sampled aerosol fraction. The health-related fraction concentrations defined in this document are often expressed as the mass of sampled particles per volume of sampled air to allow comparison with mass-based occupational exposure limit values. The conventions primarily apply to the aforementioned metrics, however, they are not applicable to situations involving limit values expressed in a different metric, such as fibre limit values defined by length, diameter, and aspect ratio, unless a measurement procedure explicitly specifies sampling a particular health-related size fraction [11]. The primary objective of this document is to establish standardized conventions for health-related particle size fractions. Sampling is generally carried out using dedicated samplers, for which there is no need to measure the aerodynamic size distribution of the airborne particles to be sampled. Samplers separating airborne particles into one or more relevant fractions are currently available. In general, no assumptions or pre-knowledge are needed on the number of modes, modal diameter(s) or width of the particle aerodynamic size distribution of the airborne particles to be sampled. The conventions in this document are intended to be used for the determination of the exposure of an average worker based on average penetration curves. This document is not intended to determine the deposited dose of an individual worker. The conventions are primarily intended for assessing workers’ exposure to airborne particles by sampling the airborne particles. This document does not apply to large particles emitted at high speed that travel due to their initial momentum, instead of being carried by the air (airborne) and aspirated into humans’ respiratory tract and aerosol samplers by suction (see Annex B). All wind speeds referenced throughout this document are based on the relative speed between the worker and the surrounding air.

Vandens kokybė. Stroncis 90 ir stroncis 89. Tyrimo metodai naudojant blyksnių skystyje skaičiavimą arba proporcinį skaičiavimą (ISO/DIS 13160:2026)

Warning — Persons using this document should be familiar with normal laboratory practice. This document does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to determine the applicability of any other restrictions. Warning — It is absolutely essential that tests conducted according to this document be carried out by suitably trained staff. This document specifies methods to determine 90Sr and 89Sr by liquid scintillation counting (LSC) or proportional counting (PC) in supply water, drinking water, rainwater, surface and ground water, marine water, as well as cooling water, industrial water, domestic, and industrial wastewater after proper sampling, handling and test sample preparation. The detection limit depends on the sample volume, the instrument used, the sample counting time, the background count rate, the detection efficiency and the chemical yield. The method described in this document, using currently available LSC and PC instruments, has a detection limit of approximately 2 mBq·l−1 and 10 mBq·l−1 for 90Sr and 89Sr, respectively, for a volume of 2 l and a measuring time of 60 000 s, which is lower than the WHO criteria for safe consumption of drinking water (100 Bq·l−1 for 89Sr and 10 Bq·l−1 for 90Sr)[4]. The methods described in this document are applicable in the event of an emergency situation. When contamination contains fresh fission products, the contribution of 89Sr to the total amount of radioactive Sr is not negligible. This document provides test methods to determine the activity concentration of 90Sr in presence of 89Sr, and to determine the activity concentration of 90Sr in large volume of water sample (>50 L). The analysis of 90Sr and 89Sr adsorbed to suspended matter is not covered by this method. Filtration of the test sample and a chemical separation are required to separate and purify Sr from a test portion of the sample as the analysis of 90Sr and 89Sr adsorbed to suspended matter is not covered by this method. It is the user’s responsibility to ensure the validity of this test method selected for the water samples tested.

Inžinerinių tinklų įrenginių atsparumo ugniai bandymai. 14 dalis. Viename paviršiuje esančių angų sandarinimo priemonės

This part of the EN 1366 series specifies a method of test and criteria for the evaluation (including field of direct application rules) of the ability of a partial penetration seal to maintain the fire resistance of a separating element at the position at which it has been penetrated by a device or devices that passes through one face of the element only. Partial penetration seals are used to seal apertures for electrical sockets, downlighters, media devices, cables and any item which requires an opening to be made in one face of the element of construction but does not include a device which passes through both faces. Supporting constructions are used in this part of the EN 1366 series to represent separating elements such as walls or floors. The supporting construction shall be a system that has been subject to a fire test in accordance with one of the following standards: EN 13381 1 for horizontal membranes, EN 13381 2 for vertical membranes, EN 1364 1 or EN 1365 1 for walls, EN 1366 3 for walls based on a standard supporting construction, or EN 1364 2 or EN 1365 2 for floors. This is referred to throughout this document as the applicable test standard for the supporting construction. This part of the EN 1366 series is used in conjunction with EN 1363 1. The purpose of a test described in this part of the EN 1366 series is to assess the integrity and insulation performance of the partial penetration seal, of the partially penetrating service(s) or device(s) and of the separating element in the surrounding area of the partial penetration seal. Where partial penetration seals are installed in loadbearing elements, it is possible that the loadbearing capacity is also considered. It is not the intention of this test to provide quantitative information on the rate of leakage of smoke and/or hot gases or on the transmission or generation of fumes. Tests in accordance with this part of the EN 1366 series are not intended to supply any information on the ability of the partial penetration seal to withstand stress caused by movements or displacements of the penetrating devices. The risk of spread of fire downwards cannot be assessed with this test. Tests in accordance with this part of the EN 1366 series do not address any risks associated with leakage of dangerous liquids or gases caused by failure of the device in case of fire.
