Abstract:

Brief introduction of the test method and testing instrument for the sealing of safety condom package

Safety condom package integrity is an important quality evaluation method to test condom package to ensure lubricant leakage performance. Because the condom package itself has a gap, leading to the possibility of lubricant leakage, so this test is very important. As an international provider of testing instruments and testing services, Jinan Chenchi introduced the testing methods of condom packaging integrity in combination with professional testing instruments, so as to provide relevant units with an understanding of condom packaging integrity testing technology.
1. Executive Standards
GB 7544-2004, ISO 4074:2002 "natural rubber latex rubber condoms - technical requirements and test methods"
2. Instruments and requirements
   MFY-01 Packaging sealing tester The vacuum tank (vacuum box) can withstand an atmospheric pressure difference, and the situation in the tank can be observed during the test. According to the standard requirements, the vacuum tank is directly vacuumized by the vacuum pump, which will affect the control of the vacuum degree due to the pulsation produced by the vacuum pump, which will easily lead to misjudgment. Mfy-01 of Jinan Chenchi Sealing tester The vacuum converter is used to make the vacuum tank form a stable vacuum and ensure the degree of equipment. It is a high-precision instrument for testing the integrity of condom packaging. It does not need to be equipped with a vacuum pump, but only needs to connect the pressure air source of the factory or laboratory.
3. Principle of condom package integrity test
Through vacuumizing the vacuum chamber, the internal and external pressure difference of the sample immersed in water (* good for filling and adding dyes) is produced, and the gas escape situation in the sample is observed to determine the sealing performance of the sample; the internal and external pressure difference of the sample is generated by vacuumizing the vacuum chamber, and whether the sample is immersed in water after the expansion and release of vacuum is observed, so as to determine the sealing performance of the sample.
4. Test method for tightness of condom package
Fill the vacuum tank with water The condom of single package is immersed in the vacuum tank, and the upper pressure plate on the back cover is required to be 25 mm away from the water surface. The excellent vacuum pressure of the vacuum tank is set to 20 ± 5 kPa, and the vacuum holding time is set to 1 min. start the test. When the vacuum degree increases, observe the condom package to show the leakage in the form of continuous bubbles, and pay attention to the inaccuracy of independent bubbles If there is no continuous air bubble after holding for 1 min, open the cover and check whether the condom package enters to further confirm whether there is leakage.
5. Evaluation of results
1) If there are continuous bubbles during the vacuum increase or vacuum holding period, it indicates that the leakage exists and the sample is unqualified
2) If the test liquid appears in the package at the end of the test, the product is unqualified
3) If there are no continuous bubbles and no test fluid is found in the package, the package is qualified.
The above is a brief introduction to condom packaging integrity test methods, for more information.
