本欧洲标准规定了将样品与实验室样品和实验室样品相结合的方法，用于亚样品和一般分析样品。 本欧洲标准中描述的方法可用于样品制备，例如当待测样品的体积密度，生物量测定，耐久性，粒度分布，含水量，灰分，灰分熔融行为，发热量，化学成分和杂质。该方法不适用于测试桥接性能所需的非常大的样品

This European Standard specifies methods for reducing combined samples to laboratory samples and laboratory samples to sub-samples and general analysis samples. The methods described in this European Standard may be used for sample preparation, for example, when the samples are to be tested for bulk density, biomass determination, durability, particle size distribution, moisture content, ash content, ash melting behaviour, calorific value, chemical composition, and impurities. The methods are not intended to be applied to the very large samples required for the testing of bridging properties.
