ISO 11269-1:2012描述了一种测定污染土壤或污染样品对陆生植物根系伸长影响的方法。 本方法适用于土壤、土壤材料、堆肥、污泥、废物或化学测试。它适用于比较已知和未知质量的土壤，以及测量有意添加到土壤中的材料（堆肥、污泥、废物）或化学品的影响。 该方法不用于测量土壤支持植物持续生长的能力。

ISO 11269-1:2012 describes a method for the determination of the effects of contaminated soils or contaminated samples on the root elongation of terrestrial plants. This method is applicable to soils, soil materials, compost, sludge, waste or chemical testing. It is applicable to the comparison of soils of known and unknown quality and to the measurement of effects of materials (compost, sludge, waste) or chemicals deliberately added to the soil. The method is not intended to be used as a measure of the ability of the soil to support sustained plant growth.
