Environment Specification 5.1 5.2 Operating Temperature - 10 C ~ + 60 C Humidity less than 80% RH Storage Temperature - 40 C ~ + 80 C at Ambient Humidity 6. Reliability Test 6.1 Exposure to high temperature Touch panel is put into a test machine at the condition of 80 for 120 hours. Then it is left at the room temperature for 24 hours or more. The measurement must satisfy the following: - Circuit close resistance: as Sec. 3.3 - Circuit open resistance: as Sec. 3.4 - Contact bounce: as Sec. 3.5 - Linearity test: as Sec. 3.6 6.2 Exposure to low temperature Touch panel is put into a test machine at the condition of -40 for 120 hours. Then it is left at the room temperature for 24 hours or more. The measurement must satisfy the following: - Circuit close resistance: as Sec. 3.3 - Circuit open resistance: as Sec. 3.4 - Contact bounce: as Sec. 3.5 - Linearity test: as Sec. 3.6 6.3 Exposure to constant temperature and humidity Touch panel is put into a test machine at the condition of 60, 90%RH for 120 hours. Then it is left at the room temperature for 24 hours or more. The measurement must satisfy the following: - Circuit close resistance: as Sec. 3.3 - Circuit open resistance: as Sec. 3.4 - Contact bounce: as Sec. 3.5 - Linearity test: as Sec. 3.6 6.4 Thermal Shock Touch panel is put into a test machine at the condition of -40 for 30 minutes, and then 80 for 30 minutes. The process is repeated by 10 cycles. Then it is left at the room temperature for 24 hours or more. The measurement must satisfy the following: - Circuit close resistance: as Sec. 3.3 - Circuit open resistance: as Sec. 3.4 - Contact bounce: as Sec. 3.5 - Linearity test: as Sec. 3.6 Changes that contribute to technical improvement are subject to alternations 2003 Bearb.
