Description


Unchangable high humidity&heat experiment

08-012-011 Environment temperature(℃) 28.0~28.1 Relative temperature(%) 68.5~68.9

1.Experiment condition & requirement

Test with unpacked and not flowing current

After keeping 40C(+-2) Leave it for 48 hours meeting 93%(+- 3 ℃) condition again.

If insulation resistance surely has to be less than 5MΩ, this experiment has to be done in 80% permitted frequancy errors of voltage.

2.Experiment result

After getting study results, process nonconductor intensity experiment.

First, products keep in a low temperature box(+70+-2) for 24 hours in a row. and then pick them up from the box and process appearance study after recovering it suitable for room temperature gradually.

First, products keep in a high temperature box(+70+-2) for 24 hours in a row. and then pick them up from the box and process appearance study afterrecovering it suitable for room temperature gradually. The appearance of products definitely dosen't have any deform and air bubble phenomenon.

Proceed a product test keeping in low and high temperature several times as meeting study requirements & conditions. An appearance research is gone ahead adjusting to room temperature. From the study results, this study has to prove that there are not any deforms or bubbling phenomenon on the appearance of the products.
