Life Testing & Reliability
Reed switches and related products are put through accelerated life tests using a wide range of load voltage and current levels. Whenever changes in material supply, design or production process take place, accelerated life tests are conducted before starting any bulk production. All life tests are documented for internal reference and are not handed out to customers as the life of our products in the field depend on various parameters such as type of load (resistive, capacitive or inductive), switching voltage, switching current, and in-rush current, frequency of operation and ambient temperature.

Accelerated life testing is the process of testing a product by subjecting it to conditions (stress, strain, temperatures, voltage, vibration rate, pressure etc.) in excess of its normal service parameters in an effort to uncover faults and potential modes of failure in a short amount of time. By analyzing the product's response to such tests, engineers can make predictions about the service life and maintenance intervals of a product.
In polymers, testing may be done at elevated temperatures to produce a result in a shorter amount of time than it could be produced at ambient temperatures. Many mechanical properties of polymers have an Arrhenius type relationship with respect to time and temperature (for example, creep, stress relaxation, and tensile properties). If one conducts short tests at elevated temperatures, that data can be used to extrapolate the behavior of the polymer at room temperature, avoiding the need to do lengthy, and hence expensive tests.
