规定尺寸、公差、测量载荷和最小断裂载荷，以及适用于散装材料输送和相关应用的相关链轮的齿隙形式和轮缘轮廓。链条设计为在每个连杆的封闭端朝前的情况下运行，以便对要输送的材料进行最大程度的刮擦。给出了五种类型的附件。链条尺寸确保了链条各个链环的完全互换性。

Lays down dimensions, tolerances, measuring loads and minimum breaking loads, together with the tooth gap forms and rim profiles of the associated chain wheels for these chains suitable for the conveying of bulk materials and related applications. The chain is designed to operate with the closed end of each link forward for maximum scraping action against the material to be conveyed. Five types of attachments are given. The chain dimensions ensure complete interchangeability of individual links of chain.
