A charged device model (CDM) test is used to define the ESD a device can withstand when the device itself has an electrostatic charge and discharges due to metal contact. This discharge type is the most common type of ESD in electronic devices and causes most of the ESD damages in their manufacturing.
There are 2,000 pounds in one ton. Tons and pounds are both units of measurement that describe mass.
In the United Kingdom the ton is defined as 2,240 avoirdupois pounds (1,016 kg). From 1965 the UK embarked upon a programme of metrication and gradually introduced metric units, including the tonne (metric ton), defined as 1000 kg (2,204.6 lbs).
