METHOD AND APPARATUS TO STRESS TEST MEDICAMENT INHALATION AEROSOL DEVICE BY INDUCTIVE HEATING

摘要

The invention relates to a method and apparatus for heat stress testing medicament aerosol inhalation devices, such as metered dose inhaler. An electrical induction work coil (24, 26, 28) is used to heat the inhalers to 55 DEG C +/-5C DEG . Heated inhalers are subsequently weighed to detect and reject nonconforming inhalers where a nonconforming amount of propellant has leaked.
