Condoms Test
Condoms are used as devices to protect against sexually transmitted diseases. These rubber boots are also used to prevent conception after intercourse. Since the spread of HIV, latex condoms have been very helpful in stunting the outbreak of the disease. Like many people still "sphere of mistaken beliefs and prejudices against the condom and its durability, it is important to expose the laborious process of manufacturing and testing Durex condoms go before reaching consumers. This process takes about four stages of manufacturing and testing for durability and multiple resistance.
The first step is strict quality tests for checking the raw materials used in the manufacture of condoms is latex rubber fine before reaching the ground. Once it passes these standards, undergo a process known as the mix? stabilizers, preservatives and vulcanizing agents are added to raw latex, and verified. Latex form Crude may curdle and turn sour over time, so the process is done quickly and efficiently.
The second step consists in a process known as salsa. The latex compound passes through the temperature-controlled tanks, and a power glass formers are dipped into vats of latex. As the first retracted, a thin layer film is formed around the wells of latex. The coating is then left with filtered air-dried to prevent contamination, then soaked and dried again for another time. Latex condoms are then laminated glass mass, then through a curing oven. They are then removed from the glass matrix by water jets, and this after an immersion process that loosens. Then let it dry again. The next step involves rigorous testing of batches of Durex condoms for ensure sustainability and stability. The batches are tested to ensure quality electronics, which involves extending much scrap metal and subjected to plants. If an error occurs in the film, almost invisible or defects are detected, the whole lot put into the container.
The fourth phase of the criterion inflation of the air, where many of the pipelines through the elasticity of condoms and density tests involving lots of explosions fills the air. Ideally, a Durex condom can hold forty liters of air or up to nine liters of water before the COP. After the completion of electronic evidence, samples of each batch for quality control tests, introduced with 300 water and suspended for three minutes. Leak then inspected by material sheets of colored paper. If you reject a large number of samples with defects or leaks, then the whole lot and eliminated. If the lot passes the test, more samples are collected and analyzed for size and thickness. Another example is to test the ability to resist the destruction of durability testing. Some samples are artificially altered to simulate aging, while the temperature increases, allowing all the guarantees of latex condoms in order to comply with their life five years before the expiry of quality.
