Notice! Which items cannot be detected by the hot and cold shock chamber!

What types of products are prohibited from testing in the hot and cold shock chamber?

In the process of testing and testing, the hot and cold shock chamber should create a sudden change of cold and heat. Such extreme environment can easily lead to drastic changes in products. For safety reasons, some products cannot be tested. What types of products are prohibited from testing in the hot and cold shock chamber?

1. Explosives:

In a high temperature environment, explosives are easy to explode, so they contain nitroglycerin, nitroglycerin, trinitrobenzene, trinitrotoluene, etc., various explosive nitrates and explosive nitro compounds. Testing is strictly prohibited. In addition, some organic oxides such as peracetic acid and benzoyl peroxide cannot be detected.

2. Combustibles:

Some flammable substances cannot be tested because they will spontaneously ignite in a high temperature environment, causing fire hazards. Therefore, natural substances such as lithium, potassium, sodium, phosphorus and other active metals are prohibited from testing, and some such as phosphide lime, magnesium powder, aluminum powder and various combustible oxide properties are strictly prohibited.

3. Flammables:

Such as containing kerosene, gasoline, turpentine, isoamyl alcohol, acid vinegar and other substances whose ignition point is above 30 ℃ and below 65 ℃. Ordinary ethane, ethylene oxide, acetone, benzene, methyl ethyl ketone and other substances whose ignition point is above -30℃ but less than 0℃. Diethyl ether, gasoline, acetaldehyde, propylene oxide, carbon disulfide and other substances whose ignition point is less than -30℃, products containing the above substances are strictly forbidden to be tested.

In addition to the above-mentioned items that are prone to explosion, combustion and other fire hazards, such as samples with radioactive substances, samples of strong electromagnetic emission sources, samples of highly toxic substances, biological samples, etc., are strictly tested and tested, and even these Substances cannot be stored inside the hot and cold shock chamber, otherwise it is easy to cause safety accidents!

Whether it is due to safety concerns or equipment protection considerations, the above substances must be prohibited from testing according to requirements, whether using different equipment such as a hot and cold shock chamber, a high temperature aging room, and a constant temperature and humidity test chamber. In the process of purchasing and using testing equipment, we will also let our technicians give a comprehensive explanation and training, so that customers can be familiar with and better grasp the use of equipment!
