Fertilizers and liming materials — Sampling and sample preparation — Part 3: Sampling of static heaps 肥料和石灰材料取样和样品制备第3部分:静态堆取样
发布日期: 2020-11-06
本文件适用于向第三方供应或准备供应的矿物肥料和石灰材料的取样,如批量或小批量,此类供应或准备供应须符合法律要求。 本文件规定了大量固体肥料或石灰材料的取样计划和方法(如果无法进行动态取样),以从大量静态堆中获取样品,以确定是否符合法律要求,尤其是与强制性或允许的法定声明的准确性有关的要求。本文件中规定的方法不适用于获取物理尺寸分析或化学分析的样品,这些样品可能会因颗粒粒度分离而改变。 本文件适用于单一营养肥料、均匀复合肥料、研磨或颗粒肥料和石灰材料。 本文件中描述的方法不适用于其他类型肥料的取样,例如混合肥料。 注:除非另有说明,否则本文件正文中使用的术语“肥料”包括石灰材料。
This document is applicable to the sampling of mineral fertilizers and liming materials supplied or ready for supply to third parties, as a lot or in smaller lots, where such supply or readiness for supply is subject to legal requirements. This document specifies plans and methods of sampling of a lot of solid fertilizer or liming material, if sampling in motion is not possible, to obtain samples from bulk static heaps in order to ascertain compliance with legal requirements, in particular in relation to the accuracy of compulsory or permitted statutory declarations. The methods specified in this document are not applicable to obtain samples for physical size analysis or for chemical analysis which may be altered by particle granulometric segregation. This document is applicable to single nutrient fertilizers, to uniform complex fertilizers and to milled or granulated fertilizers and liming materials. The methods described in this document are not suitable for sampling other types of fertilizer, for example blended fertilizers. NOTE The term 'fertilizer' is used throughout the body of this document and includes liming materials unless otherwise indicated.
