With the experimental conditions, the mechanical properties of adhesives and sealants, test conditions change, will lead to different test results.
The test environment condition is further divided into the environmental conditions during the sample pretreatment and testing. Pretreatment Environmental conditions refers to the prepared specimen for a certain time at a predetermined temperature and relative humidity environment. Test environmental conditions in which the the samples mechanical properties testing ambient temperature and humidity.
The test conditions are usually referred to herein refers to the environmental conditions, such as temperature and relative humidity of the test chamber, and some adhesives on whether there is in the test chamber air etching gas affecting the quality of the sealant is also required, such as ambient air in the presence of a sulfur compound gas, phosphorus, etc., can lead to the silicone gel platinum catalyst poisoning leaving glue does not vulcanized. In addition to the above, the test conditions are sometimes also includes test equipment, loading speed and loading method.
