1.1本规程涵盖了用于物理和化学试验的石灰和石灰石产品样品的收集和还原程序。 1.2本规程进一步涵盖了可能用于化工、农业和加工行业的石灰和石灰石产品的检查、拒收、重新测试、包装和标记。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 以下做法用于获取代表抽样批次的样品。使用的方法取决于取样材料的尺寸和类型以及测试要求。 以下做法旨在从待售材料中获取样品，而不是用于质量控制目的的抽样程序。 这些做法将用于获取实验室样本，该样本将产生结果，作为验收或拒收抽样材料批次的依据。这并不排除将这些实践用于质量控制目的。 以下做法可用于消除采样中的偏差。负责使用这些做法的人员必须经过培训，他们将认真及时地使用这些做法。 鼓励生产者和消费者就采样地点达成协议，无论是在生产者工厂还是在目的地。粗心的搬运、不当的保护和延迟装运可能会影响产品质量。最好在加载点取样。消费者有权见证所使用的抽样实践。 本规程可用于提供石灰或石灰石产品的代表性样品。由于石灰石和石灰的可变性以及采样设备的多样性，从系统规范和设备采购到设备验收测试以及实际采集最终样本，在采样的所有阶段都必须谨慎。

1.1 This practice covers procedures for the collection and reduction of samples of lime and limestone products to be used for physical and chemical tests. 1.2 This practice further covers inspection, rejection, retesting, packing, and marking of lime and limestone products as it may be used in the chemical, agricultural, and process industries. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== The following practices are to be used in obtaining samples that are representative of the lot being sampled. The methodology used will be dependent upon the size and type of material sampled and testing requirements. The following practices are intended for use in obtaining samples from material that is ready for sale and are not intended as sampling procedures for quality control purposes. These practices are to be used in obtaining a laboratory sample that will yield results serving as a basis for acceptance or rejection of the lot of material sampled. This does not preclude the use of these practices for quality control purposes. The following practices can be used to eliminate bias in sampling. The person or persons responsible for using these practices must be trained and they will be conscientious and timely in their use. An agreement between the producer and the consumer on location of sampling, either at the producer's plant or at the destination, is encouraged. Product quality can be affected through careless handling, improper protection, and delayed shipment. It is preferable to sample at the point of loading. The consumer has the right to witness the sampling practices being used. This practice may be used to provide a representative sample of lime or limestone products. Due to the variability of limestone and lime and the wide variety of sampling equipment, caution must be exercised in all stages of sampling, from system specification and equipment procurement to equipment acceptance testing and actually taking the final sample.
