ISO 3597-3:2003规定了测定由粗纱增强树脂制成的圆形截面复合材料杆抗压强度的方法。试验可在“成型”棒上进行，或在已在沸水（或其他介质）中浸泡一段时间进行预处理的棒上进行。该试验旨在对粗纱进行检查和质量控制，或评估其在树脂系统中的适用性。获得的结果不用于生成设计数据。

ISO 3597-3:2003 specifies a method for determining the compressive strength of composite rods of circular cross-section made of roving-reinforced resin. The test may be carried out on "as-moulded" rods, or on rods that have been pretreated by immersion in boiling water (or another medium) for a specified time. The test is intended for inspection and quality control of rovings or for evaluating their suitability for use in a resin system. The results obtained are not intended for the generation of design data.
