ISO 8873-1:2006规定了喷涂聚氨酯硬质泡沫塑料的最低要求和试验方法，该泡沫塑料用于建筑工地或预制（制造）设施以及非建筑应用的隔热。这种材料也被称为原位隔热。 当基材的连续使用温度超出-60°C至+80°C范围时，不得使用喷涂聚氨酯硬质泡沫塑料隔热材料。 用于确定材料性能的试验方法提供了一种比较不同多孔塑料隔热材料的方法。它们用于规范、产品评估和质量控制。它们并不是为了预测结局- 使用产品性能。

ISO 8873-1:2006 specifies minimum requirements and test methods for spray-applied polyurethane rigid cellular plastic, used as a thermal insulation for both building, whether applied on a building site or in a prefabrication (manufacturing) facility, and non-building applications. The material is also known as in-situ thermal insulation. The spray-applied polyurethane rigid cellular plastic thermal insulation is not to be used when the continuous service temperature of the substrate is outside the range of -60 °C to +80 °C. The test methods used to determine the material properties provide a means of comparing different cellular plastic thermal insulations. They are intended for use in specifications, product evaluations and quality control. They are not intended to predict end-use product performance.
