This European Standard provides guidance, and where appropriate defines procedures, for variations of certain parameters and factors associated with the design of internal and external loadbearing walls that have been tested in accordance with EN 1365-1. Data from historic standard fire resistance tests may be used as supporting information. Manufactured stone masonry units according to EN 771-5 and natural stone units according to EN 771-6 are not covered. This European Standard is not valid for reinforced masonry.

This document specifies requirements and test methods for the fire safety of candle accessories, as well as safety information ‎and requirements on how safety information will be displayed. The safety requirements and test methods specified in this document are intended to cover the most common risks. This document does not specify requirements or test methods for uncommon risks arising from the unforeseen combination of accessories and candles.

This document defines terms used in documents in the fields of environmental management systems and tools in support of sustainable development. These include management systems, auditing and other types of assessment, communications, footprinting studies, greenhouse gas mitigation and adaptation to climate change.

This document specifies safety and performance requirements for powered rescue tools manufactured after the date of publication. It is applicable to powered rescue tools which are intended for use by the firefighting and rescue services, principally for cutting, crushing, spreading, squeezing, pushing or pulling the structural parts of road vehicles, ships, trains, aircraft and building structures involved in accidents. They consist of tool(s) and the necessary system components (e.g. energy source, drive system and prime mover) and intended accessories, as defined in Clause 3. This document deals with all significant hazards, hazardous situations or hazardous events relevant to the machinery, when it is used as intended and under conditions or misuse which are reasonably foreseeable by the manufacturer. NOTE 1 The aim is to assist while extracting the casualties or to create a working space for paramedical services taking the local conditions into account. This document does not include: — tools with pneumatic drive systems or pneumatic energy sources; — tools which are single acting (for example spring /gravity return jacks, powered struts, etc.). It is not applicable to additional requirements for: a) operation in severe conditions (e.g. extreme environmental conditions such as temperatures outside the range –20 °C and +55 °C, corrosive environment, tropical environment, contaminating environments, strong magnetic fields, potentially explosive atmospheres, underwater use); b) the risk directly arising from the means provided for the portability, transportability, mobility and decommissioning of powered rescue tools during periods of their operation; c) generic tools such as, but not limited to, powered drills, angle grinders, saws, not solely intended for extrication purposes; d) tools intended to lift and/or hoist, not solely intended for extrication purposes. NOTE 2 EN 13731:2007 deals with lifting bag systems for fire and rescue services. NOTE 3 For the EU/EEA other Directives can be applicable to the equipment in the scope, for example the Electro Magnetic Compatibility Directive.

This document gives general guidance for the sampling and analysis of benzene in air by pumped sampling, thermal desorption and capillary gas chromatography. This document is in accordance with the generic methodology selected as the basis of the European Union reference method for the determination of benzene in ambient air [1] for the purpose of comparison of measurement results with limit values with a one-year reference period. This document is valid for the measurement of benzene in a concentration range of approximately 0,5 μg/m3 to 50 μg/m3. Air samples are typically collected over periods ranging from a few hours to 7 days. The upper limit of the useful range is set by the sorptive capacity (the safe sampling volume) of the sorbent and by the linear dynamic range of the gas chromatograph column and detector or by the sample splitting capacity of the analytical instrumentation used. The lower limit of the useful range depends on the noise level of the detector and on blank levels of benzene and/or interfering artefacts on the sorbent. Artefacts are typically sub ng for graphitised carbon sorbents, but higher levels of aromatic hydrocarbons have been noted in other sorbents - e.g. porous polymers. The detection limit will be approximately 1/10 of the lower concentration range. This document provides general guidance for the sampling of benzene using either a single sampler, which is changed manually after every exposure period, or a multi-sampler capable of storing and exposing multiple samples without user intervention.

This document specifies the performance criteria and test procedures for the performance test of stationary automated measuring systems (AMS) that continuously measure gases and particulate matter in, and flow of, the waste gas from stationary sources. This document supports the requirements of particular EU Directives. It provides the detailed procedures covering the QAL1 requirements of EN 14181 and, where required, input data used in QAL3.

This document specifies the general performance criteria and test procedures for the performance test of portable automated measuring systems (P-AMS) used for periodic measurements of stationary source emissions. It applies to the performance test of P-AMS based on measurement techniques specified by the standard reference method (SRM) or an alternative method (AM). The performance test is based on the general performance criteria and test procedures specified in this document and on the specific requirements specified for the SRM or AM. This includes testing of the applicability and correct implementation of the QA/QC procedures specified for the SRM or AM. This document supports the requirements of particular EU Directives.

The proposed document will specify a method for the determination of the sum of selected perfluoroalkyl and polyfluoroalkyl substances (PFAS) in drinking water using liquid chromatography mass spectrometry (LC MS/MS). The method covers at least the substances needed for the calculation of the 'Sum of PFASs ' according to Annex III, part B, point 3 of the new European drinking water directive (draft). Currently the DWD comprises the perfluoralkyl acids C4 to C13 as well as the perfluoralkyl sulfonic acids C4 to C13. Other matrices like groundwater and additional substances like HFPO-DA (GenX) and ADONA or perfluoralkansulfonamides (FASA) will be included if possible. The lower application range of the method can vary depending on the sensitivity of the equipment used and the matrix of the sample. For most compounds to which this document applies ≥0,2 ng/l as limit of quantification can be achieved. Actual levels can depend on the blank levels realized by individual laboratory. The applicability of the method to further substances, not listed in the annex of the DWD, or to further types of water is not excluded, but is intended to be validated separately for each individual case.

This document specifies minimum requirements for life rafts carried on helicopters operating in a hostile sea area or over very rough sea conditions. Life rafts covered by this document are for use by helicopter crew members and passengers in the event of a ditching or water impact. They are intended either for integration into the helicopter, or stowed in the cabin before being manhandled out of the helicopter. This document does not cover air-drop life rafts.
