This document specifies the characteristics of reference measurement standards of radioactive surface contamination, traceable to national measurement standards, for the calibration of surface contamination monitors. This document relates to alpha-emitters, beta-emitters, and photon emitters of maximum photon energy not greater than 1,5 MeV.It does not describe the procedures involved in the use of these reference measurement standards for the calibration of surface contamination monitors. Such procedures are specified in IEC 60325[6], IEC 62363[7], and other documents.NOTE Since some of the proposed photon standards include filters, the photon standards are to be regarded as reference measurement standards of photons of a particular energy range and not as reference measurement standards of a particular radionuclide. For example, a 241Am source with the recommended filtration does not emit from the surface the alpha particles or characteristic low-energy L X-ray photons associated with the decay of the nuclide. It is designed to be a reference measurement standard that emits photons with an average energy of approximately 60 keV.This document also specifies preferred reference radiations for the calibration of surface contamination monitors. These reference radiations are realized in the form of adequately characterized large area sources specified, without exception, in terms of surface emission rate and activity which are traceable to national standards.

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 focuses on automated braking at velocities below 10 km/h (2.78 m/s) and specifically aims to avoid or mitigate collisions with pedestrians, other road users (e. g. vehicles) and stationary objects including infrastructure elements (e. g. walls, pillars). These collisions mainly occur during reversing manoeuvres but this document also addresses collisions in other directions during low speed manoeuvring. ABLS requires information about the position and motion of the object, motion of the subject vehicle and driver actions, and determines if the evaluated situation represents a collision risk. If an imminent collision risk exists ABLS will automatically activate a brake action to avoid or at least mitigate the collision. This standard provides minimum requirements and test procedures. The standard will not define test objects, but will refer to the ISO 19206 series for test objects to be used. Basically, the human driver is assumed to perform or at least supervise all driving manoeuvres because the ABLS application is restricted to support only SAE Level 0 up to level 2 systems. Evasive steering manoeuvres are not part of the standard. This standard applies to light vehicles[1] only. Vehicles equipped with trailers are not within the scope of this document.

This document specifies test procedures for measuring the reference energy consumption and reference range of purely electrically propelled passenger cars and commercial vehicles of a maximum authorized total mass (in accordance with ISO 1176) of 3 500 kg and a maximum speed of 70 km/h or more.

This International Standard is applicable to all types of libraries in all countries. However, not all performance indicators apply to all libraries. Limitations on the applicability of individual performance indicators are listed in the scope clause of the description of each indicator (see Annex A). Performance indicators can be used for comparison over time within the same library. Comparisons between libraries can also be made, but only with caution. Comparisons between libraries will need to consider any differences in the constituencies of the libraries and library attributes, with a good understanding of the indicators used, limitations to comparisons, and careful interpretation of the data. There are other limitations to the performance indicators in this International Standard that depend on local factors, such as the community the library serves, service mandates, and the technological and financial infrastructure. Results from the use of performance indicators in this International Standard are intended to be interpreted with regard to these factors. Performance indicators are not specified for all services, activities, and types of use of the library, either because such indicators have not been proposed and tested at the time of formulation of this International Standard, or because they did not fulfil the criteria specified (see 5.2). The performance indicators included in this International Standard do not reflect all possible measures or evaluation techniques. This International Standard offers accepted, tested, and publicly accessible (i.e. non-proprietary) methodologies and approaches to measuring a range of library service performance. This International Standard is not intended to exclude the use of performance indicators not specified in it.

This International Standard specifies the dimensions of tapered shaft ends and hubs of fuel injection pumps and common-rail high pressure pumps for diesel (compression-ignition) engines. The specified shaft ends and hubs may be used with or without keys.

This document specifies a test method (phase 2/step 2) and the minimum requirements for bactericidal and/or fungicidal or yeasticidal activity of chemical disinfectants that form a homogeneous physically stable preparation in hard water or - in the case of ready-to-use products - with water in food, industrial, domestic and institutional areas, excluding areas and situations where disinfection is medically indicated and excluding products used on living tissues.The scope of this document applies at least to the following:a) processing, distribution and retailing of:1) food of animal origin:i) milk and milk products;ii) meat and meat products;iii) fish, seafood and products;iv) eggs and egg products;v) animal feeds;vi) etc.2) food of vegetable origin:i) beverages;ii) fruits, vegetables and derivatives (including sugar distillery);iii) flour, milling and backing;iv) animal feeds;v) etc.b) institutional and domestic areas:1) catering establishments;2) public areas;3) public transports;4) schools;5) nurseries;6) shops;7) sports rooms;8) waste container (bins);9) hotels;10) dwellings;11) clinically non sensitive areas of hospitals;12) offices;13) etc.c) other industrial areas:1) packaging material;2) biotechnology (yeast, proteins, enzymes...);3) pharmaceutical;4) cosmetics and toiletries;5) textiles;6) space industry, computer industry;7) etc.Using this document, it is possible to determine the bactericidal or fungicidal or yeasticidal activity of the undiluted product. As three concentrations are tested, in the active to non-active range, dilution of the product is required and, therefore, the product forms a homogeneous stable preparation in hard water.EN 14885 specifies in detail the relationship of the various tests to one another and to use recommendations.NOTE 1 The method described is intended to determine the activity of commercial formulations or active substances on bacteria and/or fungi in the conditions in which they are used.NOTE 2 This method cannot be used to evaluate the activity of products against mycobacteria.

This document covers the reporting of uniaxial strength data and the estimation of probability distribution parameters for advanced ceramics which fail in a brittle fashion. The failure strength of advanced ceramics is treated as a continuous random variable. Typically, a number of test specimens with well-defined geometry are brought to failure under well-defined isothermal loading conditions. The load at which each specimen fails is recorded. The resulting failure stresses are used to obtain parameter estimates associated with the underlying population distribution.This document is restricted to the assumption that the distribution underlying the failure strengths is the two-parameter Weibull distribution with size scaling. Furthermore, this document is restricted to test specimens (tensile, flexural, pressurized ring, etc.) that are primarily subjected to uniaxial stress states. Subclauses 6.4 and 6.5 outline methods of correcting for bias errors in the estimated Weibull parameters, and to calculate confidence bounds on those estimates from data sets where all failures originate from a single flaw population (i.e. a single failure mode). In samples where failures originate from multiple independent flaw populations (e.g. competing failure modes), the methods outlined in 6.4 and 6.5 for bias correction and confidence bounds are not applicable.
