ISO 12308:2017定义了买方和制造商之间交换的滑动轴承样品的类型。 在内燃机和其他系列产品领域，有必要根据用途使用不同类型的样品。 样本类型如下。 -用于在试验阶段和中试批次阶段进行的试验和检查的样品。其中包括拟合样本、原型样本和中间样本。 -用于证明质量符合质量要求（尺寸、材料和性能规范）的样品。其中包括初始样品和参考样品，必要时还包括中间样品。 注:更多信息请参见ISO 3534（所有部分）和ISO 9000。 -提供有关滑动轴承特定质量特性的选择性信息的样品，与它们是否符合规范有关。这些涉及参考和特征修改样本。

ISO 12308:2017 defines the types of plain bearing samples exchanged between purchaser and manufacturer. In the field of internal combustion engines and other series production, it is necessary to work with different types of samples depending on the purpose. Types of samples are as follows. - Samples used for tests and examinations which are carried out in the experimental stage and pilot lot stage. These include fitting samples, prototype samples and intermediate samples. - Samples used to prove that the quality is in accordance with the quality requirements (dimensions, material and performance specification). These include initial samples and reference samples and, if necessary, intermediate samples. NOTE See ISO 3534 (all parts) and ISO 9000 for further information. - Samples which give selective information about particular quality characteristics of a plain bearing, relating to their conformity with the specifications. These involve reference and characteristic modification samples.
