This part of 61340 describes the discharge current waveforms used to simulate machine model (MM) electrostatic discharges (ESD) and the basic requirements for equipment used to develop and verify these waveforms.This standard covers MM ESD waveforms for use in general test methods and for application to materials or objects, electronic components and other items for ESD withstand test or performance evaluation purposes. The specific application of these MM ESD waveforms to non-powered semiconductor devices is covered in 60749-27.
