Mask Tensile Testing Machine

The mask tensile testing machine is suitable for testing non-woven fabrics, industrial masks, medical masks, regular masks, N95 masks, medical protective clothing, protective goggles, and similar products. It can perform various tests including puncture, tensile strength, tension resistance, peeling, and shear. It meets standards such as GB, ISO, JIS, ASTM, DIN, JG, JT, YB, QB, YD, YY, QC, SY, SL, BB, and HG. The testing machine features a powerful digital display system and a microcomputer control system. Parameters such as test settings, curves, displacement, and force values can be dynamically displayed on the LCD screen. Data is collected throughout the entire testing range without segmentation. The machine uses imported servo motors and Taiwan-made reducers to drive ball screws, ensuring smooth and stable movement, thus prolonging the service life and improving the efficiency of the testing machine. Connecting to a computer enables full computer control and allows standard test reports to be printed.

According to 5.4 Mask Strap Testing Method:

5.4.2 Randomly select three samples for testing. Measure with a static tensile force of 10N for 5 seconds; the results shall meet the requirements of 4.4.2.

GB 19083-2010 Technical Requirements for Medical Protective Masks

GB 19083 Mask Tensile Testing Machine

According to GB 19083-2010, Medical Face Mask Technical Requirements, Sections 4.3 Mask Straps and 4.3.2 Test Method, the mask straps must have sufficient strength to secure the mask in place. The breaking strength of each mask strap at its connection point with the mask body shall be no less than 10N.

According to the 5.3 mask strap testing method:

5.3.1 Number of samples: Take 4 masks, open the packaging, of which 2 are subjected to temperature pre-treatment and 2 are not pre-treated.

5.3.2 Temperature pretreatment conditions:

The preprocessing conditions are:

a) Place in an environmental test chamber at 70°C ± 3°C for 24 hours;

b) Place in an environmental test chamber at -30°C ±3°C for 24 hours.

It should be allowed to recover at room temperature for at least 4 hours after temperature pretreatment.

5.3.3 Visual inspection and tensile testing device measurements shall meet the requirements of 4.3. GB/T32610-2016 "Technical Specifications for Daily-Use Protective Masks" GB/T32610 Tensile strength tester (tensile testing machine) for mask and mask strap connections according to GB/T32610-2016 Technical Specifications for Daily-Use Protective Masks

5.3 Inner Quality Table 2 Requirements for inner quality indicators: Mask and mask strap connection breaking strength/N ≥ 20

6.9.1 Extract 5 mask samples.

6.9.2 Conduct as per GB/T 13773.2. Tensile speed: 100 mm/min. The test hook is installed in the upper clamp of the tensile tester. During testing, the mask strap is vertically suspended on the test hook, and the mask body is loosely clamped along the axial direction in the lower clamp.

6.9.3 Test hook: Made of steel material, bar-shaped, with a width of (10±0.1) mm and thickness of (2±0.1) mm. One end is bent into a right-angled hook, with the hooked portion being at least (12±0.1) mm in length. The edge of the hook should be smooth. The test hook should be easily installable in the jaws of a tensile testing machine. See figure below:
