Nitrile gloves will be quality tested before packaging and transportation, and gloves that meet customer quality requirements will be transported and loaded. What are the testing items for nitrile gloves? How to test nitrile gloves to meet the requirements? Here are the details.
Nitrile Gloves Testing Items
Nitrile gloves require several indicators to be evaluated during the testing process to ensure that the quality of nitrile gloves arriving at the customer’s hands is satisfactory. The following are the testing items of nitrile gloves.
Physical detection. The instruments used are tensile testing machine and tear testing machine, which is used to test the tensile property and tear strength of nitrile gloves.
Chemical testing. The instruments used are chemical immersion test equipment, which is used to test the chemical resistance of nitrile gloves, such as acid and alkali resistance and oil resistance.
Biocompatibility testing. The instruments used include biocompatibility testing equipment, which is used to perform skin irritation and sensitization tests to assess the biocompatibility of gloves.
Microbial detection. The instrument used is a microbial incubator, which is used to test the antibacterial effect and sterility of gloves to ensure the sterility effect of nitrile gloves used by medical staff.
Watertight testing. The instrument used is a glove watertight test machine, which is used to test the air permeability and water resistance of the gloves to ensure that the gloves meet customer requirements.
Operation Process for Watertight Test System of Nitrile Gloves
Nitrile glove testing machine is used to test the tightness and pinhole size of gloves. The following are the specific steps.
Ready. Before testing nitrile gloves for water, ensure that there is no moisture on the surface of the gloves.
Fill it with water. Use the flush device to inject the appropriate amount of water (1000ml±50ml) into the glove.
Observation gloves. Carefully observe the surface of the glove for water seepage. Observe for 2-4 minutes, if there is water leakage is the place where the gloves leak, if there is no water leakage, it means that the gloves are well sealed. Ignore leaks within 40mm of the sleeve edge.
Record the results. Record the leakage of several gloves accurately and prepare for subsequent handling. Run the test on the next batch of gloves.
Follow-up Procedure After the nitrile gloves are tested, the water in the gloves should be drained in time, because the long-term moisture residue on the surface of the gloves will affect the performance of the gloves and breed bacteria.
In addition, nitrile gloves for different purposes have different requirements for test results, and nitrile gloves for semiconductor clean rooms may have more stringent test requirements.
How to Choose Glove Watertight Testing Machine
High precision testing. Choose a high accuracy glove watertight testing machine to ensure the test results are trustworthy.
High automation. High automation is the development trend of glove machines, which choose automatic or semi-automatic according to customer needs.
High compatibility. Make sure the glove watertight tester is suitable for different types and sizes of gloves.
Meets industry standards. Such as ASTM, ISO, etc.
Glove Watertight Test System Maintenance
The technician of the glove factory must master the maintenance work of the glove production line. The following are the maintenance points of the glove watertight test system.
Keep equipment clean and hygienic. Remove dust on the surface of the machine in time to prevent affecting the test results of the gloves.
Regular maintenance. Check the key components of the glove watertight testing machine regularly and replace the worn parts in time.
Regular commissioning of equipment. The test accuracy of the glove watertight testing machine must be ensured.
