Gb19083-2010 technical requirements for medical protective masks

合成血液渗透测试;

2 mL synthetic blood was sprayed into the mask at a pressure of 10.7 千帕 (80 毫米汞柱). 面罩内部不应发生渗透.

YY 0469-2011 synthetic blood penetration test of surgical masks:

2 mL synthetic blood was sprayed into the mask at a pressure of 16.0 千帕 (120 毫米汞柱). 面罩内部不应发生渗透.

YY 0469-2011 synthetic blood penetration test of surgical masks:

Sample quantity: test with 3 samples.

样品前处理: 样品至少经过预处理 4 h at temperature (21)C和相对湿度 (85)%, and the test was carried out within 1 min after being taken out.

测试流程: the sample is fixed on the sample fixture on the instrument, 和 2 mL表置于距样品中心30.5cm处

The surface tension was 0.002n /m with a pressure of 16.0 千帕 (120 毫米汞柱)

The needle tube with a diameter of 0.84mm was sprayed in a horizontal direction to the target area of the sample under test. 目视检查在 10 移除后的s.

Result treatment: check the inner side of the sample for penetration.If visual inspection is suspicious, use a absorbent cotton swab or similar to rub the inside of the target area and determine if there is synthetic blood penetration.The results shall meet the standard requirements.
