标准摘要
[中文适用范围]： 本国际标准描述了一种实验室测试方法，用于测量医用口罩对合成血液飞溅渗透的抵抗力。 该国际标准主要涉及医用口罩中使用的材料或某些材料结构的性能。 该测试方法不涉及医用口罩的设计、结构、接口或其他可能影响医用口罩提供的整体保护及其操作的因素（例如过滤效率和压降）。 该测试方法不评估医用口罩作为防止空气传播途径污染或防止沉积在医用口罩上的雾化体液渗透的性能。 [外文原描述]： ISO 22609:2004 describes a laboratory test method for measuring the resistance of medical face masks to penetration by a splash of synthetic blood. ISO 22609:2004 primarily addresses the performance of materials or certain material constructions used in medical face masks. The test method does not address the performance of the medical face mask's design, construction, interfaces or other factors which may affect the overall protection offered by the medical face mask and its operation (such as filtration efficiency and pressure drop). ISO 22609:2004 does not evaluate the performance of medical face masks as a protection against contamination via airborne exposure pathways or in the prevention of the penetration of aerosolized body fluids deposited on the medical face mask.
