It is applicable to the resistance of the protective clothing to the synthetic blood penetration under different levels of test pressure.

Standard:

GB 19082-2003《Medical disposable protective clothing technology requires synthetic blood penetration test method》;

ASTM F1670 / F1670M - 17a Standard Test Method for Resistance of Materials Used in Protective Clothing to Penetration by Synthetic Blood

working principle:

Under constant pressure, the synthetic blood was tested on the protective clothing material, and the penetration of blood was synthesized on the visual inspection material.

Sample preparation:

In the sample of each protective suit, 3 pieces (75*75) mm are randomly selected. When conducting the experiment on the composite or multi-layer materials, the edges should be sealed and the diameter shoud be kepted greater than 57mm for testing.

Instrument characteristics:

1. The instrument adopts the air source which can provide (0.5---30 + 0.1)kPa pressure to continuously pressurize the sample, and is not subject to the space limitation of the test site;

2. The range of air pressure can be set freely and set range (0.5---30)kPa;

3. Color touch screen display, Chinese and English operation menu, user can freely choose the language operation;

4. The sample surface is made of imported special aluminum profiles, with light material, smooth surface and never rust;

5. The instrument adopts imported special aluminum drawing panel with metal buttons;

6. The instrument is equipped with a sample automatic clamping device without manual clamping;

7. The test tank is equipped with special fixed device to facilitate customer operation;

8. The test tank is made of high quality 316 stainless steel, with high transparent and high intensity protective cover.

9. Square metal block: open space is more than 50%; Under 30kPa, the bending is less than 5mm;

10. The precision of instrument time control is less than 0. 1 second;

11. High quality metal baking paint is used for the whole machine shell.

Technical indicators:

1. Pressure range and measurement accuracy: 0 ~ 0.04MPa (4mH2O) (31.4kg) accuracy: + 1kPa.

2. Sample size: 75mm * 75mm, under pressure area: 28.26 square centimeters.

3. Power supply: AC220V, 50Hz, 100W.
