包含与矩形截面的工业、刚性、模制、层压管以及矩形和六角形截面的杆相关的定义和名称，以及需要满足的一般要求。 模制型材使用酚醛树脂或环氧树脂作为粘合剂，并使用以下增强材料:纤维素纸、棉布或玻璃布。 本标准涵盖天然颜色的杆和管以及含有色素或其他添加剂的杆和管。 符合本标准的材料符合既定的性能水平。 然而，用户为特定应用选择材料时，应基于该应用中充分性能所需的实际要求，而不是仅基于本标准。

Contains the definitions and designations related to, and the general requirements to be fulfilled by, industrial, rigid, moulded, laminated tubes of rectangular cross-section and rods of rectangular and hexagonal cross-section. The moulded sections are manufactured using either phenolic or epoxy resins as the binder and using the following reinforcements: cellulosic paper, cotton cloth or glass cloth. This standard covers both rods and tubes of natural colour and those containing colouring matter or other additives. Materials which conform to this standard meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this standard alone.
