ISO 3385:2014规定了用于室内装潢等承重应用的柔性多孔材料厚度损失和硬度损失的测定方法。它提供了一种评估用于承重室内装潢的基于橡胶乳液或聚氨酯的柔性多孔材料使用性能的方法。
该方法既适用于从石板材料上切割的标准尺寸试样,也适用于成型部件。测得的厚度损失和硬度损失与使用中可能发生的损失有关,但不一定相同。
ISO 3385:2014无意作为疲劳设备的详细工程设计规范。
ISO 3385:2014 specifies a method for the determination of loss in thickness and loss in hardness of flexible cellular materials intended for use in load-bearing applications such as upholstery. It provides a means of assessing the service performance of flexible cellular materials based on rubber latex or polyurethane used in load-bearing upholstery.
The method is applicable both to standard size test pieces cut from slabstock material and to shaped components. The measured loss in thickness and loss in hardness are related to, but are not necessarily the same as, the losses likely to occur in service.
ISO 3385:2014 is not intended to function as a detailed engineering design specification for fatigue apparatus.
