BS EN 14984:2016规定了两种测量添加效果的方法（方法A和方法B） 使用相同的基本原理，使用任何声称对土壤有石灰作用的材料。方法A测量因添加任何声称有效的材料而引起的土壤pH值变化 在一个月的时间内对标准土壤进行石灰化处理。方法B使用一系列定义的方法评估声称具有石灰效果的任何材料的效率 在长达2.5年的时间内对土壤和土壤进行测量。这些方法不适用于方法A中粗于6.3 mm或方法A中粗于20 mm的矿物产品 方法B，根据EN 12948测定。注:这些方法允许在受控气候条件下对产品进行比较，但不能替代 现场实验。交叉引用:EN 1482-1EN 1482-3EN 12048ISO 8190:1992EN 12049ISO 8189:1992EN 12945EN 12948EN 13040EN ISO 3696ISO 3696ISO 3310-1ISO 3310-2ISO 10390:2005ISO 11272ISO 11277ISO 11465ISO 14235NF X31-130EN 13971ISO 5725-1:1994ISO 5725-2:1994ISO 11274购买本文件时可提供的所有当前修改件均包含在购买本文件中。

BS EN 14984:2016 specifies two methods (method A and method B) of measuring the effect of the addition of any material claimed to have a liming effect on the soil, using the same basic principles.Method A measures the changes to the soil pH resulting from the addition of any material claimed to have a liming effect on a standard soil, measured over a period of one month.Method B assesses the efficiency of any material claimed to have a liming effect, using a range of defined soils and measured over a period of up to 2,5 years.The methods are not applicable to mineral products coarser than 6,3 mm for method A or 20 mm for method B, determined according to EN 12948.NOTE These methods allow comparison of products under controlled climatic conditions but do not replace field experiments.Cross References:EN 1482-1EN 1482-3EN 12048ISO 8190:1992EN 12049ISO 8189:1992EN 12945EN 12948EN 13040EN ISO 3696ISO 3696ISO 3310-1ISO 3310-2ISO 10390:2005ISO 11272ISO 11277ISO 11465ISO 14235NF X31-130EN 13971ISO 5725-1:1994ISO 5725-2:1994ISO 11274All current amendments available at time of purchase are included with the purchase of this document.
