This document covers hinged and pivoted steel (any kind) and aluminium based framed, glazed doorsets or openable windows. Throughout this document, the term "doorset" will be used to cover both doorsets and door assemblies. It prescribes the methodology for extending the application of test results obtained from fire resistance test(s) conducted in accordance with EN 1634-1. Subject to the completion of the appropriate test or tests selected from those identified in Clause 4, the extended application can cover all or some of the following examples: - integrity (E), integrity & radiation (EW) or integrity & insulation (EI1 or EI2) classification, - glazed elements including vision panels and framed glazed doorsets, - air transfer grilles (louvres and/or vents), - side, transom or over panels, - items of building hardware, - decorative and protective finishes, - intumescent seals and non-intumescent (smoke, draught or acoustic) seals, - alternative supporting construction(s). This document does not cover horizontal doorsets. The effect on the Classification ‘C’ for the doorsets following an extended application process is not addressed in this document.

 This document specifies a method for the photometric determination of dissolved chromium(VI) using manual, e.g., hand photometry, or automated static, e.g., discrete analyser system, or automated dynamic techniques, e.g., flow injection analysis (FIA), continuous flow analysis (CFA), or ion chromatography with post-column derivatization (IC-PCR). The choice of the analytical technique to be used and needs-based sample preparation (e.g., matrix elimination) enables the determination of chromium(VI) in concentrations ≥0,02 µg/l in raw water, drinking water, surface water, aqueous eluates, cooling water and treated wastewater, provided that the Matrix does not contain any reducing substances. Typical areas of application for the static techniques as well as FIA and CFA are samples with chromium(VI) concentrations ≥2 µg/l. When using cuvettes with large optical path lengths, e.g. >100 mm, the range of application can be extended to concentrations <2 µg/l chromium(VI) (Annex A; Annex B; Annex C, Clauses C.1 and C.2). When using coupled techniques (e.g. IC PCR), chromium(VI) concentrations ≥0,02 µg/l can be determined (Annex C, Clause C.3). In some waters with reducing ingredients, chromium(VI) losses can occur just a few hours after sampling. Therefore, the method was not validated for leachate from landfills and raw sewage.

This document specifies the general “design for recycling” guidelines for EPS raw materials. It provides guidance on the impact of specific design characteristics on the recyclability of the product in practice and recommended design options to ensure that the product is recyclable, including target values and performance ranges, where applicable. It also provides a definition of recyclable product and of design for recycling. This document refers to the recycling processes of EPS products. The sorting and collecting steps are not part of this document. This document takes into account all currently known processes that are suitable to enable the circular economy for insulation materials. Particular attention is paid to ensuring that the most energy-efficient processes are given preference, especially mechanical recycling, unless reuse is already ruled out. For some of these processes, practical experience has been gained over many years, so a basic knowledge base for the development of a guideline is already available. At the same time, it is important to also take into account future-oriented processes, for which at the moment little but increasing experience is available or which have so far only been implemented on a small scale.

This document provides guidance on identifying and assessing impacts of climate change on wastewater systems and on developing strategies for the adaptation to these impacts. The assessment of the impacts is based on the assessment principles described in ISO 24566-1 Assessment Principles. This document also provides examples of some of the impacts of climate change on drinking water systems and of the responses that have been implemented by municipal water services or by the relevant jurisdiction (e.g., municipality or region served by the service). The examples of responses illustrate adaptation strategies that have been applied.

This document specifies a method for calculating the expected hearing threshold levels of adult populations due to various levels and durations of noise exposure; it provides the basis for calculating the risk of hearing impairment according to various formulae when the hearing threshold levels at commonly measured audiometric frequencies, or combinations of such frequencies, exceed some certain values. This document is based on statistical data and therefore cannot be applied to the prediction of the hearing loss of individual persons. NOTE 1 This document does not specify frequencies, frequency combinations, or weighted combinations to be used for the evaluation of hearing impairment; nor does it specify a hearing threshold level (fence) which it is necessary to exceed for hearing impairment to exist. Quantitative selection of these parameters is left to the user. All sound pressure levels stated in this document do not consider the effect of hearing protectors which would reduce effective exposure levels and modify the frequency spectrum at the ear. Because there is evidence indicating a transition between metabolic exhaustion and mechanical damage in the inner ear, exposure to sound pressure exceeding 200 Pa (140 dB relative to 20 μPa) is not recommended. The measure of exposure to noise for a population at risk is the equivalent continuous A-weighted sound pressure level normalized to an 8 h working day, or A-weighted noise exposure level, Lp,A,8 h or ' Lp,A h , 8 , for a number of years of exposure. This standard applies to noise at frequencies less than 10 kHz that is steady state, intermittent, fluctuating, irregular, or complex with A-weighted noise exposure levels between 70 and 100 dB (daily A-weighted sound exposures between 0,115 × 103 and 115 × 103 Pa2s). Formulae are presented to calculate the statistical distributions of hearing threshold levels at a range of audiometric frequencies due to exposure to noise as a function of level of noise exposure and duration of exposure (in years). Values of effect of noise, N, do not distinguish between male and female populations. The database for values of N in Table 1 was derived from people who typically started work around age 20 and whose noise exposures continued for many years; thus, this database is most accurate for populations of workers whose age minus years of exposure is about 20. NOTE 2 Although the models of hearing loss are based on data assumed to stem primarily from populations exposed to occupational noise, they may be used, with some caution, for estimating the effects of comparable non occupational exposures. NOTE 3 The prediction method for Lp,A,8 h presented is based primarily on data collected with essentially broadband, steady-state, non-tonal noise. The prediction method for noise environments which include substantial impulsive/impact noise uses a kurtosis-adjusted noise exposure level normalized to an 8 h working day, ' Lp,A h , 8 . To calculate hearing threshold levels and also to calculate the risk of acquiring hearing impairment due to noise exposure, it is necessary to make use of a database for age-associated hearing threshold levels for a comparable population. This document includes a highly screened otologically normal population (in accordance with ISO 7029) and examples of unscreened populations of five typical industrialized societies. The users of this document may choose a comparable population according to their particular requirements. NOTE 4 All data and procedures presented in this document are based on deliberate simplifications of experimental data where the daily sound exposure duration did not exceed 12 h. The resulting approximations restrict the validity to the stated ranges of the variables, percentiles, sound exposure levels and frequency ranges.

Reasons are given for the need for more than one method and advice is given on the choice of method to be used. This document establishes a categorization scheme for dustiness to provide a standardized way to express and communicate the results to users of the bulk materials. Details of the scheme for each method are given in EN 15051-2 and EN 15051-3. This document is applicable to powdered, granular or pelletized bulk materials. This document is not applicable to test the dust released during mechanical reduction of solid bulk materials (e.g. cut, crushed) or to test application procedures for the bulk materials.
