口罩EN14683检测,口罩VFE检测,口罩PFE检测
EUROPEANSTANDARD EN 14683
欧盟标准 EN 14683
This standardis intended to help facilitate the choice of surgicalface masks in the European Market by standardizing the information andperformance data required for the masks.
本标准旨在利用标准化的信息和口罩的性能数据来帮助欧盟市场方便的选择口罩。
There are threetest methods used to classify surgical masks:
有三种测试方法用来给口罩进行分类:
1. BacterialFiltration Efficiency in vitro (BFE) (ASTM F2101-07)
体外过滤率(BFE)(ASTM F2101-07)
Classification:
分类
BFE => 95% TYPE I
BFE => 98% TYPE II
2. BreathingResistance (Delta P)
呼吸阻抗 它是指气体在流经呼吸道及呼吸装置时的耗功加总值。
3. SplashResistance (ASTMF1862-07)
防溅阻力 指防止血液\体液等溅撒 物的阻止能力.
Test is used to determine the resistance penetration of potentially contaminated fluid splashes.
我公司是做:
1:新MDR法规和MDD指令的欧盟CE认证,CE*四版评价报告更新/编写
2:欧盟自由销售证书,欧盟授权代表(德国,荷兰,英国),
3:ISO9001/ISO13485认证以及咨询
4:FDA注册,FDA510K,FDA验厂/陪审和翻译
5:MDSAP咨询,国内注册证,生产许可证的申请
口罩EN14683检测含三部分检测:过滤率,呼吸阻抗,防溅阻力。
其中,过滤率就是常说的BFE检测,BFE/PFE/VFE是不同级别的过滤效果检测,PFE是比BFE级别更高的过滤效果检测,VFE是病毒过滤效果检测,检测实验室均为美国NELSON
检测项目(2014年新标准):BFE合并Different Pressure检测、合成血喷溅试验、微生物负载

有三种测试方法用来给口罩进行分类:
1. Bacterial Filtration Efficiency in vitro (BFE) (ASTM F2101-07)
体外过滤率(BFE)(ASTM F2101-07)
• Test is used to determine the amount of infective agent that is retained by the surgical facemask, which is directly related to the amount of bacteria released through the mask into the air of the surgical theatre.
• 这个测试是用来确定口罩上残留的源,此源直接影响到手术室空气中由口罩中释放出的数目。
• To test, a controlled flow of air containing an aerosol with a controlled concentration of Staphylococcus aureas is driven through a sample of the surgical mask containing all layers. The average size of the aerosol droplets is around 3.0 Micron. The number of bacteria that passes the sample is compared to the number that passes without the mask sample.
• 测试方法:使用一个喷雾装置,用来释放出固定流量的空气流,这个空气流包含着一定浓度的金葡萄球菌,让这股空气流穿过包含所有层的口罩。喷雾口的平均尺寸为3微米。通过样品的数目和没有样品时的数目进行比较。
• A higher BFE percentage indicates a better protection level for the patient against infective agents from the OR staff.
• 这个BFE比值越高,说明口罩能更好的保护病人不易因为手术人员而感染。
Classification:
分类
• BFE => 95% TYPE I
• BFE => 98% TYPE II
• A different BFE test called the "Modified Green & Vesley" or BFE in vivo has been used frequently in the past. This test method always provides extremely high values, but does not really differentiate between different quality surgical facemasks. The BFE in vivo test method is therefore not part of the new EU standard.
• 不同的BFE测试可以称为“修改版的Green&Vesley”或者体外BFE,这种方法在过去经常被使用。这种测试方法能提供较高的值,但并不真正的区分出不同质量口罩。这种体外BFE测试方法因此没有成为新的欧盟标准的一部分。
