This document specifies a semi-static method for determining the effects of contaminants on growth and survival of young snails, usually Helix aspersa aspersa Müller. The animals are exposed via the cutaneous and digestive route using a test substrate (artificial or natural soil according to the objective of the study) to which defined amounts of the following are added: — substances, mixtures or preparations; — soils (contaminated or of unknown quality) or waste materials. This test takes into account the possible changes in the test substance, preparation, soil or waste material because the test mixtures are prepared and renewed every week during the 28-day test period. A static method may be implemented in addition to the semi-static method (optional). This method is described in Annex A. This method does not apply to substances for which the air/soil partition coefficient is greater than one, or to substances with vapour pressure exceeding 300 Pa, at 25 °C.

DIN EN ISO 11508:2018 土壤质量.粒子密度的测定(ISO 11508-2017);德文版本EN ISO 11508-2017

This International Standard describes two methods for the determination of particle density of soils calculated from the mass and the volume of soil particles. The first method is applicable to fine soil (under 2 mm diameter) and the second method is applicable to both porous and nonporous gravel and stones (larger than 2 mm diameter). The particle density may be used for the calculation of the proportion of solids and of the porosity of soil layers in combination with the procedure given in ISO 11272.
