口罩astm测试，口罩astm报告，口罩astm认证

1.1本规范涵盖用于制造医疗面罩的材料的测试和要求，这些材料用于提供医疗保健服务（如手术和患者护理）.

1.2本规范提供了医疗面罩材料性能的分类。医用口罩材料的性能基于对细菌过滤效率，压差，亚微米颗粒过滤效率，合成血液渗透性和可燃性的测试。

1.3本规范未涵盖医用口罩设计和性能的所有方面。该规范并未具体评估与防护性和透气性有关的医用口罩设计的有效性。本规范也不适用于呼吸防护，这对于某些医疗保健服务可能是必要的。

1.4以si单位或其他单位表示的值应单独视为标准。每个系统中规定的值必须彼此独立使用，而不能以任何方式组合。以下预防性警告仅适用于本规范第9节的测试方法部分：本标准并不旨在解决所有标准问题。与使用有关的安全问题（如果有）。本标准使用者的责任是在使用前建立适当的安全和健康措施，并确定法规限制的适用性。 1.1this specification covers testing and re for materialsused in the construction of medical face masks that are used inproviding health care services such as surgery and patientcare.

1.2 this specification provides for the classification ofmedical face mask material performance. medical face mask materialperformance is based on testing for bacterial filtrationefficiency, differential pressure, sub-micron particulatefiltration efficiency, resistance to penetration by syntheticblood, and flammability.

1.3 this specification does not address all aspects of medicalface mask design and performance. this specification does notspecifically evaluate the effectiveness of medical face maskdesigns as related to the barrier and breathability properties.this specification does not also apply to respiratory protection,which may be necessary for some health care services.

1.4 the values stated in si units or in other units shall beregarded separately as standard. the values stated in each systemmust be used independently of the other, without combining valuesin any way.the following precautionary caveat pertains only to thetest methods portion, section 9, of this specification: thisstandard does not purport to address all of the safety concerns, ifany, associated with its use. it is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limitationsprior to use.

astm测试一个是细菌过滤效率，颗粒物过滤效率，压力表，血液渗透，阻燃，这几项，欢迎致电
