This document specifies the fundamental formulae for use in the tooth root stress calculation of straight and helical (skew), Zerol and spiral bevel gears including hypoid gears, with a minimum rim thickness under the root of 3,5 mmn. All load influences on tooth root stress are included, insofar as they are the result of load transmitted by the gearing and able to be evaluated quantitatively. Stresses, such as those caused by the shrink fitting of gear rims, which are superposed on stresses due to tooth loading, are intended to be considered in the calculation of the tooth root stress, sF, or the permissible tooth root stress sFP. This document is not applicable in the assessment of the so-called flank breakage, a tooth internal fatigue fracture (TIFF). The formulae in this document are based on virtual cylindrical gears and restricted to bevel gears whose virtual cylindrical gears have transverse contact ratios of eva < 2. The results are valid within the range of the applied factors as specified in ISO 10300-1 (see also ISO 6336-3[1]). Additionally, the given relationships are valid for bevel gears, of which the sum of profile shift coefficients of pinion and wheel is zero (see ISO 23509). This document does not apply to stress levels above those permitted for 103 cycles, as stresses in that range could exceed the elastic limit of the gear tooth.

This document specifies the methods of calculation of the load capacity of bevel gears, the Formulae and symbols used for calculation, and the general factors influencing load conditions. The Formulae in ISO 10300 (all parts) are intended to establish uniformly accepTable methods for calculating the pitting resistance and bending strength of straight, helical (skew), spiral bevel, Zerol and hypoid gears. They are applicable equally to tapered depth and uniform depth teeth. Hereinafter, the term “bevel gear” refers to all of these gear types; if not the case, the specific forms are identified. The Formulae take into account the known major factors influencing pitting on the tooth flank and fractures in the tooth root. The rating Formulae are not applicable to other types of gear tooth deterioration such as plastic yielding, micropitting, case crushing, welding, and wear. The bending strength Formulae are applicable to fractures at the tooth fillet, but not to those on the active flank surfaces, to failures of the gear rim or of the gear blank through the web and hub. Pitting resistance and bending strength rating systems for a particular type of bevel gears can be established by selecting proper values for the factors used in the general formulae. If necessary, the Formulae allow for the inclusion of new factors at a later date. The rating system of ISO 10300 (all parts) is based on virtual cylindrical gears and restricted to bevel gears whose virtual cylindrical gears have transverse contact ratios of eva < 2. Additionally, the given relations are valid for bevel gears of which the sum of profile shift coefficients of pinion and wheel is zero (see ISO 23509).

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 one method for the desalination by poultices of porous inorganic materials constituting cultural heritage. The desalination methodology can be applied to salt-loaded porous inorganic materials either affected by salt weathering and/or to allow conservation treatments incompatible with soluble salt(s) contamination, or to prevent salt damage where contamination is known to be present. In all cases the desalination aims to decrease salt content.Furthermore, this document gives the fundamental requirements for the desalination operation and guidelines for the choice of the most appropriate poultice components according to the characteristics of the substrate and types/quantities of salt(s) present in order to optimize the desalination process.

This International Standard specifies one of the methods for evaluating the habitat function of soils and determining effects of soil contaminants and substances on the reproduction of Folsomia candida Willem by dermal and alimentary uptake. This chronic test is applicable to soils and soil materials of unknown quality, e.g. from contaminated sites, amended soils, soils after remediation, industrial, agricultural or other sites of concern and waste materials. Effects of substances are assessed using a standard soil, preferably a defined artificial soil substrate. For contaminated soils, the effects are determined in the soil to be tested and in a control soil. According to the objective of the study, the control and dilution substrate (dilution series of contaminated soil) are either an uncontaminated soil comparable to the soil to be tested (reference soil) or a standard soil (e.g. artificial soil). This International Standard provides information on how to use this method for testing substances under temperate conditions. The method is not applicable to volatile substances, i.e. substances for which H (Henry's constant) or the air/water partition coefficient is greater than 1, or for which the vapour pressure exceeds 0.013 3 Pa at 25 °C.

This document is applicable to the system engineering of all bogies and running gear. It specifies the requirements to achieve: — a satisfactory design of bogie or running gear — validation of the design within its operating envelope— a maintenance planto ensure the relevant performance and safety criteria are maintained.No requirements are set for other systems components that are attached to the bogies or running gear, except to establish that a satisfactory interface has been provided.NOTE Specifications that relate to bogies and running gear can only be considered in the context of a specific vehicle application. Therefore, the performance, including safety, can relate only to the bogies and running gear as part of a vehicle configuration and not to the individual elements of the bogies or running gear.
