How does the manufacturer test the quality of gloves
Since there are many application scenarios for disposable gloves, they have to undergo strict review before they are ready for sale. In automobiles, cleaning, and agriculture, workers will deal with some chemical substances. In the medical industry, workers need a preventive tool to resist pathogens. Therefore, manufacturers will conduct extensive testing to ensure which industry is suitable for which disposable gloves。
What is the minimum quality standard?
Glove inspection is carried out based on the sampling standard table (AQL). This test method originated from the American Society for Testing and Materials (ASTM), which is a company founded on the standards of various industries around the world.
AQL is suitable for testing batches of disposable gloves. It is a method of testing glove standards based on percentages. For example: there is an AQL of 3.0 in a batch of 100 gloves, which means that three gloves in this batch are tested as unqualified. The AQL standard for medical gloves is 1.5 or lower. If more than 3 gloves fail the test, then the entire batch of gloves does not meet the inspection standards.
How to test gloves?
The best way to check the quality of gloves is to use the pinhole leak test, which is also widely used in the testing of medical gloves. This is because even if there is a small crack on the surface of the glove, it will make the wearer very easy to come into contact with pathogens. During the test, the manufacturer will fill the glove with one liter of water, close the cuff of the glove, and hang the glove upside down. During the test, the glove is suitable for medical grade gloves if there is no leakage of water.For example, KIEYYUEL disposable medical nitrile gloves have passed SGS and CE-level AQL standard tests, and the quality can be fully guaranteed.
An interesting fact about the AQL standard for disposable gloves is that manufacturers usually produce medical-grade and industrial-grade gloves on the same production line. Industrial-grade gloves will also pass the manufacturer's standard quality tests, but do not need to be tested by the US Food and Drug Administration. But this does not mean that the quality of industrial-grade gloves is unsafe. AQL is a cost-effective testing method. It only provides classification for manufacturers to ensure which industry is suitable for which gloves.
