Safety Standared UL 796 covers component safety requirements for printed wiring boards for use as components in devices or applications. Testing analyzes characteristics such as flammability,maximum operating temperature,electrical tracking, heat deflection, and direct support of live electrical parts.
An operating temprature is the temprature at which an electrical or mechanical device operates.The device will operate effectively within a specified temprature range which varies based on the device function and application context,and ranges from the minimum operating temperature to the maximum operating temperature(or peak operating temprature).Outside this range of safe operating temperatures the device may fail.Aerospace and military-grade devices generally operate over a broader temprature range than industrial devices;cinsumer-grade devices generally have the lowest operating temperature range.
It is one component of reliability engineering.
