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.
There are 2204 pounds in a metric ton. There is one ton in a metric ton. Some books use the convention that a ton is 2,000 pounds (US) and a 'tonne' or 'metric ton' is 1000 kgâ¦ or 2204 pounds. The question 'how many tons are in a metric ton' is ambiguous. The answer could be 1.1 (if we assume the first unit is a US ton) or 1 exactly if we assume the first unit is a metric ton.
