This document specifies the crucial steps of a quantitative real-time polymerase chain reaction (qPCR) method to quantify the abundance of specific mRNA molecules extracted from Daphnia magna.The method allows the identification of molecular responses to exposures for potentially toxic substances through the analysis of the abundance of specific mRNA molecules. In this document, the central genes involved in reproductive and toxic responses are included.NOTE The selection of genes can be adapted to specific exposure conditions, for example, exposure to known toxic substances, by adding genes known to respond to a specific insult.The present method allows for rapid, robust and sensitive detection of molecular responses and can be used to analyse the toxic effects of water leachates from soil and waste. The method gives information of the concentration of a substance or test-liquid at which toxic effects begin to occur prior to observations of reproductive or toxic effects at higher levels of organization, which reduces the need for the use of safety factors in toxicity assessment.The method is useful in several types of risk assessment. In this document, the genes studied are appropriate for the assessment of the risks when recycling materials and for the classification of waste, but the method can be adapted to other types of risk assessment by including other genes.

This document specifies the basic formulae for use in the determination of the surface load capacity of straight and helical (skew), Zerol and spiral bevel gears including hypoid gears, and comprises all the influences on surface durability for which quantitative assessments can be made. This document is applicable to oil lubricated bevel gears, as long as sufficient lubricant is present in the mesh at all times. The formulae in this part of ISO 10300 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 ISO 6336-2[1]). 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). The formulae in this document are not directly applicable to the assessment of other types of gear tooth surface damage, such as plastic yielding, scratching, scuffing or any other type not specified.

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 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 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.
