Approval and Certification 认证

Surgical Masks 外科口罩

需要AS 4381认证,以及TGA注册,主要用来防止病人的唾液、飞沫 

Industrial P2 Respirators and Surgical N95 Respirators 工业P2口罩

需要AS/NZS 1716认证。P2口罩必须通过独立认可实验室的检测并且符合标准要求,比如过滤效率96%,方可申请通过独立的认证机构比如DNV GL Australia进行AS/NZS 1716的认证。  

针对一次性N95口罩AS/NZS 1716 & EN149部分检测项目比较

EN 149 产品类别 Particle filtering half mask EN 149: 2001 FFP2 NR KN95
FFP2 是欧标EN 149根据TIL和过滤效果filtering efficiency来分类;P2是澳标AS/NZS 1716的filtering efficiency
1. TIL 呼入泄露总量 total inward leakage 标准条款 
要求:10个人50个不同的动作,共50次 10 subjects x 5 ‘individual exercise’
   Cl. Limit
EN 149 Cl.7.9.1
Cl.8.5
46 out of 50, < 11% for FFP2 and 8 of 10, < 8%
50次动作的46次测试结果<11%,10个人中8个人的均值<8%
AS/NZS 1716 Cl. 2.2.2 A mean inward leakage / individual exercise < 8%
The mean inward leakage / subject < 8%
2. CO2 的含量
  Cl. Carbon dioxide content of the inhalation (Limit) 限值
EN 149 Cl.7.12& 8.7 no more than 1.0%  不能超过1.0%
AS/NZS 1716 Cl. 3.2.2 no more than 1.0%
  Cl. Test Parameter 测试方法
EN 149 Cl.7.12& 8.7 Breathing machine: 25 cycles /min, 2.0 L/Stroke, 5% CO2 content 呼吸机:25次/分钟;每次2L;5% CO2
AS/NZS 1716 Cl. 3.2.2, E5.3, E4(c) Breathing machine: 20 cycles /min, 2.0 L/Stroke, 5% CO2 content
3.  呼出阻力
  Cl. Breathing resistance – exhalation  
EN 149 Cl.7.16 160 L/min, < 3.0 Mbar
AS/NZS 1716 Cl.3.2.5 85 L/min, < 120 Pa 
GB 2626 Cl.5.5
Cl.6.6
85 L/min, <250 Pa, Test result: 46.3 Pa and 45.9 Pa
  Cl. exhalation Inhalation 呼入阻力
EN 149 Table 2 Tested at 160 L/min
 
1. Test at 30 L/min
2. Test at 95 L/min
AS/NZS 1716 3.2.5 Test at 85+/- 2 L/min
limit: < 120 Pa

5.5 每个样品的总吸气阻力应不大于350Pa,总呼气阻力应不大于250Pa Cl.5.5 The total inhalation resistance of each sample shall be no more than 350Pa and the total exhalation resistance shall be no more than 250 Pa
6.6.4 将被测样品佩戴在匹配的试验头模上,调整面罩的佩戴位置及头带的松紧度,确保面罩与试验头模的密合。再将通气量调节至(85+/-1)L/min,测定并记录呼气阻力。 Cl.6.6.4 Seal the particle filtering half mask on the Sheffield dummy head, and adjust properly the wearing position of the mask with the tightness of the head strap to ensure that the mask is closely closed with the test dummy head. The continuous stream of air is then adjusted to (85+/-1) L/min, and the exhalation resistance is measured and recorded.
