本国际标准规定了使用脉冲核磁共振（NMR）快速测定商品油料种子油和水含量的方法。适用于含水量小于10%的油菜籽、大豆、亚麻籽和葵花籽。对于含水量较高的种子，在通过脉冲核磁共振测定含油量之前，必须进行干燥。注1:该方法已在油菜籽、大豆、亚麻籽和葵花籽中进行了试验。然而，这并不排除其适用于在测量温度下油为液体的其他商业种子。注2:再现性值通常高于通过干燥方法获得的值（ISO 665）

This International Standard specifies a rapid method for the determination of the oil and water contents of commercial oilseeds using pulsed nuclear magnetic resonance (NMR). It is applicable to rapeseeds, soya beans, linseeds and sunflower seeds with a water content less than 10 %. For seeds with higher water contents, drying is necessary before the oil content can be determined by pulsed NMR. NOTE 1 This method has been tested with rapeseeds, soya beans, linseeds and sunflower seeds. This does not, however, preclude its applicability to other commercial seeds whose oil is liquid at the temperature of measurement. NOTE 2 The reproducibility values are generally higher than those obtained by the drying method (ISO 665)
