Mechanical testing of medical gloves is conducted to ensure the safety and reliability of the gloves during use, which mainly includes tests such as tensile strength, elongation rate, and puncture resistance. Here are some commonly used testing methods and standards:
1. **Tensile Strength and Elongation Rate Testing**:
- According to the ASTM D412 standard, the glove material is made into a dumbbell-shaped specimen, which is then stretched at a constant speed until it breaks, and the tensile strength and elongation rate are measured.
- The ASTM D3577 and D3578 standards specify the testing methods for the tensile properties of surgical rubber gloves, requiring a minimum tensile strength range of 14¨C24 *** and a minimum elongation rate of 400¨C750%.
- For testing, a tensile and compression testing system is used, such as the Mecmesin MultiTest 0.5-i, equipped with pneumatic flat jaw grips and conical needle tips for puncture resistance fixtures, with software that automatically calculates various strength parameters.
2. **Puncture Resistance Testing**:
- The ISO 374-1 standard analyzes the puncture force of gloves in contact with and without chemical substances.
- During testing, the glove specimen coated with chemical liquid is fixed at the mouth of a bottle, and a conical probe is moved downward at a certain speed to penetrate the specimen, calculating the peak load of the punctured glove.
3. **Waterproofness Test**:
- The glove is fixed on a cylindrical tube, and water is poured in to observe whether the glove leaks within a certain period of time.
4. **Thickness Test**:
- According to the ISO 4648 standard, a contact-type thickness gauge is used to measure the thickness of the glove.
5. **Aging Test**:
- After aging the specimen at 70℃¡À2℃ for 168 hours, the breaking force and breaking elongation rate are tested again.
These tests ensure the strength and durability of medical gloves in actual use, protecting medical staff and patients from infection. Manufacture |
